It is free and aims at rendering more features than OpenCycleMap, in order to take into account the diversity of cycling practices. For urban bikers (bike commuting), we decided to render all available types of cycle tracks and lanes, in a lateralized manner, as well as key POIs such as bicycle parkings, parkings shared with motorbikes, specific bike features (elevators / ramps), speed limitations, and surfaces of the highways to avoid paving stones. For bicycle tourers, we also rendered bicycle touring routes as well as a set of essential POIs (emergency services, shelters, tourism, shops) as wel las elevation data to help you design your bike journey. Building on the excellent quality of the OpenStreetMap data in Paris, we are also in touch with some local bicycle organizations to gather feedback and help them have a quick and detailed view of the current state of the cycling road infrastructure in the city. As such, a particular emphasis has been put on well rendering the quality of the infrastructures (clearly differentiating bidirectional cycle ways, dedicated lanes versus shared with public transport, etc) as well as some new elements which were not previously rendered: bike boxes and bumps. Designing a map render for every cyclist is a challenging task: bike infrastructures are usually parcimonious and very tightly bound to the road network, which makes bike-first visualizations not as readable as wished. There are also a wide variety of cyclist profiles, each requiring slightly different emphasis. CyclOSM is our attempt at tackling this challenge. In this talk, we will briefly sum up the main rendered features as well as discuss the design decisions and the difficulties of bicycle-oriented rendering. This talk will also provide a basic "getting started" summary, to help you start contributing and hacking this new render. A demo is already available at https://cyclosm.github.io/cyclosm-cartocss-style/example.html (limited to a few French cities at the moment, soon extended).

We worked with various Mapillary communities and users to test the value of this new form of data. In this presentation, we’ll explore two campaigns. The first was the ***#mapillary2osm*** campaign which made point data available to six communities (Antwerp, Austin, Ballerup, Kyiv, Melbourne, São Paulo) in GeoJSON files and then encouraged map edits to turn each point into nodes on OpenStreetMap. Each location was given a 25 km^2 focus area and encouraged to add these points with the hashtag ***#mapillary2osm***, with the results being shared on a public leaderboard. The second was a project led by undergraduate students from the University of Washington’s Department of Geography. This particular project focused on a suburb of Portland, Oregon with the goal of validating and verifying Mapillary data in order to enrich OpenStreetMap.

Check it out and enjoy mapping buildings! sotm2019-1181-osminedit-a-simple-indoor-editor Mapping Adrien PavieHannes GeißelmannAndreas DirksThomas Sontag en The demand for Indoor Navigation is increasing worldwide. Unlike outdoor GPS navigation, indoor navigation is still rare and expanding at a slow pace. That is in part due to the fragmented landscape for positioning technology and in part due to the absence of indoor maps. Successful mapping starts with good tools. That's why we have developed a tool for mappers to create and edit indoor maps easily. With OSMInEdit we aim to repeat the OSM success story for the indoor space. The foundation for the OSM indoor data model is already laid out. The “Simple Indoor Tagging” schema is the community consensus on how to represent indoor data in OSM. It allows tagging of indoor specific content and is actively used and supported by the community. Popular OSM editors like ID and JOSM lack essential features that are required to map buildings - you need, for example, specific styling to filter data level by level, specific indoor tags, and indoor specific validation rules. OSMInEdit is an easy-to-use use web-based map editor that solves these specific challenges.

So far, field mapping exercises are largely manual, cumbersome, or requires internet connectivity. OpenStreetMap has an active mobile editing ecosystem, but they don't offer the same editing experience as iD for beginners. Most often mapping campaigns need an equally good tool that allows edits from the field to verify existing data and improve data quality. Observe is a cross-platform, offline-first field mapping tool for OpenStreetMap, perhaps the first of its kind. Our primary goal was to build an application that makes field observation easy, and provide comparable experience to iD on Android and iOS — with some success. Observe focuses on browsing OSM data, and allows users to add new points, or verify existing information. The edits made offline are stored on the phone, and uploaded when the mapper goes online. Observe is a product of several iterations of user research and a couple of years of conceptualization. The talk will: - introduce motivations behind building Observe - look at some specific use cases in campaign management - share internals of building the application - discuss challenges around offline editing and our approach to conflict resolution - gather feedback and launch a developer edition of the application false https://pretalx.com/sotm2019/talk/39SBT8/ https://pretalx.com/sotm2019/talk/39SBT8/feedback/ Hörsaal Ost Talk 2019-09-21T16:30:00+02:00 16:30 00:20 Lightning Talks sotm2019-2483-lightning-talks-ii General Ilya ZverevArnalie VicarioAndi TabinasMinh NguyễnChristopher BeddowMarco Minghini en ## OpenStreetMap intrinsic quality assessment using “Is OSM up-to-date?” web application <em>Marco Minghini and Francesco Frassinelli</em> <p>Approaches to analyze OpenStreetMap (OSM) intrinsically, i.e. based on the history of data, have become an established way to achieve a wide range of final goals, most importantly to study its quality. Started in 2017, “Is OSM up-to-date?” is an open source web application licensed under AGPL and mainly written in Python. It can be also run in the command line or inside a Docker container. The target beneficiaries of the software are OSM users and communities, who need to assess the quality of data in a given area to decide whether to use it or not as well as where mapping efforts should be best directed, and OSM researchers and scholars, who can use it as a tool to help in their OSM quality studies. The project has a dedicated wiki page (https://wiki.openstreetmap.org/wiki/Is_OSM_up-to-date), source code is hosted on GitHub (https://github.com/frafra/is-osm-uptodate) and a demo is available at https://is-osm-uptodate.frafra.eu. Using the OSM API, the web application generates history-based, quality-oriented visualizations of OSM nodes and ways having at least one tag for any rectangular user-selected region. Such visualizations (on top of a grayscale OSM basemap) are available for the following criteria: date of creation, date of last edit, number of versions, number of different contributors who edited that node or way, and frequency of update. When an OSM node or way is clicked, a popup shows its values for the previously mentioned criteria as well as the list of currently available tags and the links to the OSM iD editor (in edit mode on that node or way), history and details of that node or way (both linked to the OSM website). A number of additional features to further improve the analysis of quality is currently planned (see https://github.com/frafra/is-osm-uptodate/labels/enhancement).</p> ## Deriviste - Click and Go Photo Mapping <em>Christopher Beddow</em> <p>There are many OSM editing tools, but only one that allows the user to click inside a Mapillary image to add new data to the map. Richard Fairhurst's Deriviste tool was a quick experiment that proved this was possible, but it's important to ask more questions. How useful is the tool? How accurate and precise is it? How can it be improved?</p> ## Fifty states in 12 years and five minutes <em>Minh Nguyễn</em> <p>A whirlwind historical tour of the OpenStreetMap project in the United States.</p> ## "MAPAbabae": Using OSM as a Tool for Mapping with Women and For Women <em>Andi Tabinas, Arnalie Vicario</em> <p>We would like to share how we, as part of the Social Welfare and Development agency of the Philippines (DSWD), have utilized OSM to have a collaborative and gender-inclusive approach of mapping points of interests catering to women.</p> ## Reverse Geocoding Is Not Simple <em>Ilya Zverev</em> <p>Having seen a dozen of different geocoders, I did not expect to find myself writing another one. But here I am, tasked with making a reverse geocoder better than the industry-standard Nominatim. Turns out it is a fun and not so straightforward task.

The answers are "Yes" and "Yes", and this talk will show how this can be done with relatively simple code, and just inside a web browser! sotm2019-945-vr-map-using-osm-data-in-a-webvr-environment User Experiences Robert Kaiser en Mixed Reality (XR), i.e. Virtual and Augmented Reality, opens up new possibilities for 3D visualizations of OpenStreetMap data. With WebXR and Mozilla's A-Frame library, it's really simple to create cross-device XR experiences running right in the browser with very little code, and scaling well from mobile via laptop/desktop to fully immersive VR headset experiences. VR Map is a demo that brings all that together and allows you to walk or "fly" through a virtual model of the real world courtesy of live OSM data from the Overpass API. The talk will describe WebXR as Mixed Reality APIs for the browser and A-Frame as Mozilla's library to make it really simple to build WebXR scenes. Then, it will dive into how those technologies were used together with live OSM data to create the VR Map demo and show how it enables people to move through virtual models built from that real-world data. This will include a dive into an actual live demo, and into the HTML+JavaScript code used to create this experience. Through all that, it hopefully will show an interesting new perspective on OpenStreetMap - and hopefully inspire developers to build similar experiences. false https://pretalx.com/sotm2019/talk/9TMRYN/ https://pretalx.com/sotm2019/talk/9TMRYN/feedback/ Hörsaal Ost Talk 2019-09-21T17:30:00+02:00 17:30 00:20 Hikar is an OSM-based augmented reality navigation app for walkers and hikers, showing OSM ways overlaid on the camera feed of the device and, in the latest version, virtual signposts pointing the way to nearby points of interest. This technical talk will introduce Hikar, detail the many new developments since it was last presented at SOTM Birmingham 2013, and describe how it works in technical detail. sotm2019-1284-hikar-osm-augmented-reality-for-walkers-across-europe Software Development /media/sotm2019/images/DETEML/hikar1.png Nick Whitelegg en Augmented reality (AR) has gained a great deal of media attention in recent years, helped in no small measure by the massive mainstream success of Pokemon Go. However, AR has a great deal of potential for real-world applications too, particularly for outdoor users, which has only partly been realised to date. A number of geospatial AR apps have been available for some years, including Layar and Wikitude, primarily focusing on points of interest (POIs), but many are proprietary and closed-source. One potential but little-explored application of AR is to provide navigation tools for hikers and other outdoor users, by overlaying paths and hiking trails on the camera feed of the device. An early version of the app discussed here, Hikar, was presented at SOTM Birmingham 2013, with the footpaths and trails sourced from OSM; however this version was difficult to use and was restricted in coverage to England and Wales. After a hiatus, development on Hikar has restarted in the past year, partly inspired by increased mainstream interest in AR and helped a great deal by the availability of global Terrarium elevation tiles and increasingly-affordable web hosting. The app (available on Google Play) now covers the whole of Europe and shows not only OSM ways but also virtual signposts, showing the distance and direction to nearby OSM POIs at path junctions, helping people navigate in the field. Virtual signposts support Greek and Cyrillic as well as Roman alphabets. The talk will include an in-depth technical discussion on how the virtual signposts feature has been implemented. Problems and issues with the app as it stands (such as the realism of the path and signpost placement, and inaccuracies with GPS and mapping data) will be discussed, along with strategies for resolving those problems, and future work (which may have already started by SOTM) will be outlined, including the use of computer vision and surface detection to more accurately place the virtual data within the real world. false https://pretalx.com/sotm2019/talk/DETEML/ https://pretalx.com/sotm2019/talk/DETEML/feedback/ Hörsaal West Extended Talk 2019-09-21T11:30:00+02:00 11:30 01:30 This session provides an entertaining yet informative introduction into everything you need to know about OpenStreetMap. sotm2019-1289-introduction-to-osm-how-it-s-made-and-how-it-s-used OSM Basics Frederik RammThomas Skowron en If you're new to OpenStreetMap, or maybe just know a little, then this session will fill you in on everything you need to know about OpenStreetMap.

This is the purpose of Overpass API and Overpass Turbo. sotm2019-1235-share-edits-and-insights-with-the-overpass-tools OSM Basics Roland Olbricht en Our aim is to create special interest maps like this one for [historic street lamps](http://osmstreetlight.bplaced.net/#16/51.2339/6.7829), this one for [vehicle restrictions](http://maxheight.bplaced.net/overpass/map.html?zoom=14&lat=49.4&lon=8.68&layers=B0000000TFFTFFFFFFFF), or simply [all restaurants by cuisine](https://overpass-turbo.eu/s/I6z). An introduction to the Overpass API, to Overpass Turbo and the query language will be given. The aims are that the participants are afterwards able to filter for one for more tags, variants of tags, one or more keys, geographical regions, and combinations of such criteria. The Overpass API also supports to count objects, to dump them to GeoJSON, to retreive them in QGIS, in uMap, or a couple of [other downstream tools](https://dev.overpass-api.de/overpass-doc/en/targets/index.html).

It will probably see further development this summer. During this workshop, you can learn how PT_Assistant can help you to map itineraries for public transport, cycling and hiking. Interactively if you bring a computer with Java installed on it. sotm2019-921-mapping-public-transport-and-cycling-itineraries-using-josm-s-ptassistant-plugin Mapping Polyglot en Mapping public transport is considered as hard to do. Cycling itineraries aren' t entirely trivial either. PT_Assistant is meant to help to make mapping these more efficient. Firstly it visualises the itineraries, focusing on what matters for public transport, i.e. numbered stop sequences. highlighted ways, so the itinerary you are currently working on stands out. Secondly, warnings are reported in the validator about 'gaps', vehicles traveling against oneway traffic, or not heeding turn restrictions and several more that are next to impossible to achieve without some extra programming. Last summer a routing helper was added, which means a lot less manual splitting of ways. Also, if an itinerary is mapped once and (parts of it) are used by other lines, the helper will propose larger sequences of ways to add in one go. It is already possible to use PT_Assistant for mapping walking and cycling routes, but that functionality will be extended further this summer. The reason to integrate it in the same plugin, even if the underlying principles differ, is that it fixing the public transport lines, but leaving other route relations in a "broken" state is not very nice either. Last year a "wizard" was added to help set up your JOSM environenment with MapCSS styles, Overpass Queries, Oneclick settings and accompanying toolbar buttons. So, if you want to learn more about how it can help you map route relations, come and join us, preferably with a laptop with JOSM installed on it. false https://pretalx.com/sotm2019/talk/Z9VBKM/ https://pretalx.com/sotm2019/talk/Z9VBKM/feedback/ Kleiner Hörsaal Workshop 2019-09-21T14:00:00+02:00 14:00 01:00 OSMBC is the Content Management System to produce weeklyOSM in recently nine languages sotm2019-1344-how-to-contribute-to-weeklyosm-via-the-cms-osmbc OSM Basics Manfred Reiter en weeklyOSM is the sister project of the German OSM blog (also well known as Wochennotiz). The infrastructure of weeklyOSM was created within the Comenius project "My community and my history in OpenStreetMap" by an international team from five countries and is being consigned, little by little, into the hands of the community. The aim is to share OSM news in a range of languages in addition to German and English. OSMBC "theFive" wrote a dedicated content-management system: OSMBC (OSM Blog Collector) back in mid 2015, especially designed for the needs of Wochennotiz and weeklyOSM. This system has been in use since WN #272. OSMBC allows news articles to be "collected" by the weeklyOSM team. This process previously was done entirely by the German Wochennotiz team. Later English and Spanish translations of Wochennotiz were managed within the tool, but these days increasingly articles are collected in different languages and cross-translated in a flexible workflow enabled by the OSMBC software. Despite the name, it is not limited to blogs. The team also checks international mailing lists and other channels to include any news that is relevant. The system supports "markdown" formatted text, for each article, and groups them into categories. These are ultimately converted to HTML and put into the wordpress blog each week. OSMBC is free and open source software and available on github. OSMBC is continuously adapted to the needs of the editorial team. For some time now, a guest mode has been available, the use of which will initially be discussed. The aim of the workshop is to familiarize beginners with the system. In addition, useful functions that can be used for translation will be shown using concrete examples. true https://pretalx.com/sotm2019/talk/JJUFQT/ https://pretalx.com/sotm2019/talk/JJUFQT/feedback/ Kleiner Hörsaal Workshop 2019-09-21T16:30:00+02:00 16:30 01:00 We create an individualized map based on OSM using uMap sotm2019-1341-umap-for-newbies OSM Basics Manfred Reiter en uMap lets you create a map with OpenStreetMap layers and embed it in your site.

Since then many things have changed and improved in version 0.12 and beyond more data can be stored even without knowing Java or GraphHopper internals, but still the storage of those properties is done efficiently. A world wide graph with some basic useful road properties like highway, toll, tunnel, bridge, ferry, width, height, surface, maxspeed and access fits into a routable graph of under 25GB, i.e. just 60% of the planet PBF. GraphHopper allows you to keep this either in memory if you need high speed or serve the graph from the hard drive (incl. cache) to keep the costs low or use your development laptop. Developers and data analysts are enabled to store more features while preserving fast data access. The advantage of the graph-based storage of GraphHopper over a usual database is that the road connectivity can be directly exploited. This is a work in progress and we'll show what is already possible to provide a more flexible routing, data analysis and in-browser visualization with Leaflet. E.g. for routing purposes so called "what if" scenarios can be done to show the impact of a bridge construction via isochrones or reachable areas and also potential problems for HGV vehicles can be outlined. false https://pretalx.com/sotm2019/talk/P8AG7K/ https://pretalx.com/sotm2019/talk/P8AG7K/feedback/ Großer Hörsaal Talk 2019-09-22T10:00:00+02:00 10:00 00:20 Satellite imagery has materially enhanced OpenStreetMap and improved editing and validation.

We want to do this to clear up any confusion or future questions the community might have. We will further demonstrate how we have integrated Maxar imagery into the OpenStreetMap ecosystem. In both iD and JOSM, we have developed a custom plugin that connects to the commercial satellite imagery service and provides a carousel view of available imagery in the visual extent of the editor. Images are arranged temporally providing opportunities to compare areas against different time periods. The plugin also applies the metadata from the image as tags on the feature, including source:imagery, source:imagery:layerName, source:imagery:sensor, and source:imagery:date. Leveraging these services and applying the metadata of the imagery enhances the mapping experience, enriches OSM data, and improves the end-user benefits. false https://pretalx.com/sotm2019/talk/TVSA9F/ https://pretalx.com/sotm2019/talk/TVSA9F/feedback/ Großer Hörsaal Talk 2019-09-22T10:30:00+02:00 10:30 00:20 Lightning Talks sotm2019-2484-lightning-talks-iii General Alina NegreanuSibabrata ChoudhuryBeata Tautan-JancsoIlya ZverevSaid Turksever en ## Human in the Loop: Verifying Machine-Generated Data for Better Maps <em>Said Turksever</em> <p>Machine-generated map data has the potential to considerably accelerate mapping at scale.

As a result quite a few open-source geocoders using OpenStreetMap data have been developed and have matured in the last years. Nominatim, Pelias, Photon, Carmen, there are many to choose from. They all have in common that they offer a general purpose search for addresses, places and, to a more limited extent, places of interest. OpenStreetMap has inspired the creation of many domain-specific maps. Be it maps for specific features like brew pubs, camping or power infrastructure or for activities like cycling, hiking or child entertainment. A general purpose search on these maps is often not satisfying. The special features might simply not be available in the generic geocoders. And when they exist, they do not get the prominence appropriate for the map. This talk explores ways to improve the search experience for such special-interest maps. We start with simple approaches to boost results using existing web APIs and then look into different ways for creating a small custom domain-specific search engine. We discuss advantages and disadvantages of the different approaches and show common pitfalls for implementations.

So, it can be valuable to know the exact location and characteristics of each solar PV installation - large solar farms, and small domestic installations. In this talk we'll discuss how this all fits together. We'll talk about solar power tagging/mapping in OSM, for both large and small, to make it easy for people to map but also useful for the power network analysis. We'll also share our explorations of crowdsourcing and automation machine vision, and the use of other data sources such as government open data to guide the mapping process. We have already mapped a significant portion of the UK's solar capacity, and trialled some crowdsourcing and machine vision tools. We will show visualisations and analyses of the work that's been done so far, and consider how to scale this worldwide. false https://pretalx.com/sotm2019/talk/EBHGTW/ https://pretalx.com/sotm2019/talk/EBHGTW/feedback/ Großer Hörsaal Talk 2019-09-22T15:00:00+02:00 15:00 00:20 The talk describes the use of OSM as part of an asset management process using a crowd of National Trust staff, volunteers and the public to maintain an network inventory of an estimated 20,000 km of paths (both Public Rights of Way and permissive paths). The process pro-actively notifies local staff of changes to enable on-ground validation.  The process required the definition, and consistent application of, a UK standard for path tagging. sotm2019-1381-national-trust-managing-a-path-inventory-in-osm-towards-an-open-paths-standard-in-osm-for-the-uk Data Analysis & Data Model Huw Davies en The National Trust (NT) is a charity set up to look after special places in England, Wales and Northern Ireland. Now the largest land owner in the UK, NT cares for more than 250,000 hectares of land including 775 miles of coastline, 100,000 hectares of statutory wildlife sites, 28,000 buildings and structures, 300 historic mansions and gardens. The NT operates a membership business model which provides members with complimentary access to our pay-for-entry visitor attractions, but also seeks to provide extensive free access to the countryside. The pay-for-entry visitor attractions welcomed 2.5 million visitors in 2018, and an estimated 300 million visits to countryside sites. Recent internal analysis estimates that NT look after a network of 20,000km of footpaths which comprises both legally designated ‘Public Rights of Way’ (25%) and permissive paths (75%). Permissive paths are those where access to members and/or the public is provided, and the condition of the path is monitored. Currently there is no single digital inventory of Public Rights of Way or permissive paths in the UK. The Paths Project is capturing a digital inventory of paths on National Trust in order to: • Demonstrate how NT are fulfilling our core purpose of providing access to special places. • Improve asset management including maintenance and enhancement of the path network, • Provide a digital base for trail curation and enhanced visitor experiences. A review of options concluded that the OpenStreetMap would be the best system for management of the National Trust Paths Inventory. This enables the capture of a digital path data to a defined standard to be carried out by the Trust’s extensive local staff, volunteer network and also any citizens with an interest in paths.  The data is then available royalty-free to anybody for the development of products to encourage appropriate access to our special places. This approach is not without challenges. The constancy of path tagging in OSM is not currently suitable for describing the access to the path network. In order to ensure the paths data met the NT needs we worked with OSM UK, and other partners to apply consistent data standards for tagging paths in OSM. This standard is specific to the UK context and enables to differentiation between legal rights of way and permissive paths. In working with local staff to review the current representation a number of challenges were identified relating to the official register of paths and the reality on the ground. This is an evolving area and as the project progresses it is expected that other challenges will emerge. The project set-up an automated process for notifying local staff to changes in their area of knowledge so that changes could can be validated against the reality on the ground.  This work provided an interesting technical and organisational challenge and is a somewhat novel approach for large asset owning organisations seeking to utilise OSM and the power of the crowd to manage asset data. The initial focus of the project is on the existence of paths and the legal basis for access. Once this is captured additional attributes relating to accessibility, condition will be considered. Whilst this project is still to be completed, other potential asset types that could be managed in OSM in this way have been identified. The true value of a UK wide paths inventory will only be realised by having a comprehensive, authoritative and trusted dataset. This cannot be achieved by NT alone. When the project is suitable mature NT will make available any parts of the process to other organisations to encourage adopt a similar approach. false https://pretalx.com/sotm2019/talk/VDUV9A/ https://pretalx.com/sotm2019/talk/VDUV9A/feedback/ Großer Hörsaal Talk 2019-09-22T15:30:00+02:00 15:30 00:20 The project created from the cooperation between GeoLab (Universidad de Antioquia), and SiCLas (group of cyclists), both present in Aburrá Valley (Colombia), proposes a collaborative mapping by bicycle users as an urban transport mode. The data generation from existing cycling infrastructure will allow an improvement of OSM database, and an optimization in route calculation. In addition, the incorporation of surveys will allow the generation of thematic maps, such as the association of gender with mobility. sotm2019-1330-collaborative-cartography-of-cycling-infrastructure-for-route-and-thematic-maps-in-medellin-colombia Mapping Carolina Ortega Espinosa en The cities of the Aburrá Valley, with Medellín as a core city, present a network of bike paths, and the theme of sustainable and non-motorized mobility is gaining increasing importance in public policies in the region. Meanwhile, everyday cyclists, who use the bicycle on a daily basis as a mode of transport, know that this cycling infrastructure has lacks in several aspects, such as a fragmented presence in the territory, non-direct routes, among others. In addition, the cycling infrastructure in OpenStreetMap is not completely mapped or has erroneous information, this represents a problem for cyclists who wish to transport themselves through the city and identify the most appropriate route to their destination. It does not have accurate and relevant information for users such as the location of bicycle parking, bike-share stations and multimodal stations, among others. These reasons represent a disincentive for more people to choose the bicycle as a mode of transport. For these reasons, this project aims to map the existing formal cycling infrastructure, urban transport routes used by cyclists, to optimize route calculation, and aims to create a platform that allows the visualization of safety data, infrastructure, environmental problems (air quality) and gender mobility, among others, in which the information of shared eventualities can be collected and uploaded by the users. From the cooperation created between the GeoLab research group of the University of Antioquia – YouthMappers chapter, and the SiClas group of cyclists, both entities present in the Aburrá Valley, a considerable number of cycling activists will be mapping the cities of the valley with the OSM platform and tools open. The discussion of the existing tags in OSM for the mapping of cycling infrastructures is a topic of interest in the project, and can contribute to a discussion of the creation of new tags in OSM. The status of current information will be verified and corrected and the missing routes mapped. The tools to generate the thematic maps will be KoBo Collect, Mappillary, among others. false https://pretalx.com/sotm2019/talk/KATR7E/ https://pretalx.com/sotm2019/talk/KATR7E/feedback/ Großer Hörsaal Talk 2019-09-22T16:30:00+02:00 16:30 00:20 An analysis of Notes, based on local experience of managing notes. sotm2019-1256-notes-can-we-do-better-experiences-and-ideas-from-the-frontline- Data Analysis & Data Model /media/sotm2019/images/SKVRRL/osm_notes.png Chris Fleming en Over 1 735 319 notes have been added to OSM, currently 416 224 notes are still open. Even looking at a small area such as Edinburgh, the city I live in, we have around 10 new notes added every day. It's interesting to note the motivation of people adding notes, many are added by regular experienced mappers for changes that need to happen in the future, some are added by local businesses or anonymous users altering us to problems on the map and some by non technical users for changes that are required. These note encapsulate a few different categories: Things that can be fixed quickly and the note closed straightaway. We then have short to medium term notes, such as shops closing or road closures that may be for issues for between days and months. Then finally then some of the very long term items, such as the construction of the Forth Crossing, New Hospitals or Housing Estates that may be tracking developments for years. But with so many notes remaining open, issues can very easily be missed. I will briefly review some of the tools available for tracking notes, and talk about how we deal with notes including some of our local tests with using github issues to track some of the longer term issues.

But as more accuracy is needed in routing, cartography, and other uses, is this data model good enough? We are trying to represent spaces as flows, which result in fundamental compromises and inaccuracies. This talk will discuss real-world cases where this compromise is increasingly problematic. sotm2019-1038-is-the-osm-data-model-creaking- Data Analysis & Data Model Martin Lucas-Smith en OpenStreetMap was designed to enable ordinary people to create open geodata that anyone can use and maintain easily. Traditional GIS concepts such as layers are dispensed with in order to make editing simple and accessible. In the same way that the web would never have taken off if HTML were not so accessible and tolerant of mistakes, this simplicity in OSM has meant a low barrier to involvement. However, as OSM is becoming more widely used in the mainstream, the need for accuracy and quality is becoming more and more important. Cyclists need detailed turn data to enable high-quality routing that takes full account of safety. Satnav companies, need lane data, which is difficult to represent accurately. Pedestrian routing is barely in its infancy and high quality routing for people walking or using wheelchairs is hard to achieve. At its root, OSM tries to represent spaces as flows (lines). This results in fundamental compromises and inaccuracies. What is good for routing is not always good for cartography, and vice-versa. For instance, a street containing cycleways with pavements either side is usually represented as a single line with attributes. However, it is extremely challenging to represent properly all the parts of the street, and in general people simply don't bother: a single line with large numbers of attributes is unwieldy to edit (even when hidden by editor GUIs), and just as challenging for a router to interpret. Continual changes in the width of a street cannot be easily represented without segmenting the street heavily and creating a mess. Temporary disappearance of lanes makes editing complex. Routing ultimately ends up as a lowest common denominator result. The alternative method of representing this same street is as a series of individual lines. But this is equally problematic. In this model, the street loses its coherence as a single entity - humans think of it as a street with multiple uses (walking, cycling, driving, trees). Where people have done this, attributes such as street names need to be kept in sync, and in practice separate pavements often fail to have names attached. Concepts such as the ability to cross from one side of the road to the other (or even switch lanes) are not modelled, with the result that a router may take the user to the end of the street then back down. And cartography ends up showing a series of parallel lines which looks messy and does not match the human perception of a street. The bicycle tagging page on OSM provides a perfect demonstration of the current problem: https://wiki.openstreetmap.org/wiki/Bicycle It shows the complexity of representing many common scenarios, with increasingly incomprehensible tagging combinations. No router implements anything like all of this, and even expert OSM contributors would shy away at bothering to add this data. Cycleways indeed are a good general example of inconsistent tagging. Cycleways separate to a road are sometimes tagged as an attribute of the street and sometimes as a separate geometry. What about a hybrid/stepped cycle lane of the kind seen in Copenhagen - is that a cycle lane or a cycleway? Do lane counts include cycle lanes or not? How is obstructive car parking represented? Is the one-way indication applicable to the cycle lane on the road? And so on. Another example is junctions. Should traffic signals be treated spatially (i.e. represent the location of the traffic heads), or should they be treated linearly so that routing works properly? How should the linear model work accurately when there is only a single geometry for multiple directions? Have a look at the roads around the Arc De Triomphe in Paris - it is completely impossible for a routing engine to work out exactly how many signal delays should actually be attributed based on the presence of the marking of traffic signals in the data: https://www.openstreetmap.org/#map=17/48.87391/2.29536 This talk will discuss these cases, and provide a starting point for discussion on what should be done to improve the situation. As people are ever keener to add more detail to the map, and as more and more mainstream users look to OSM, we have to ask whether the current model is arguably creaking too heavily. Is there a way that we can represent spaces as a set of interconnected flows in some way? The speaker, Martin Lucas-Smith, is one of the developers of CycleStreets, one of the earliest and most established dedicated cycle routing engines. As such, he has spent many years considering the kinds of tradeoffs represented by the current OSM data model. false https://pretalx.com/sotm2019/talk/DW7WW8/ https://pretalx.com/sotm2019/talk/DW7WW8/feedback/ Großer Hörsaal Talk 2019-09-22T17:30:00+02:00 17:30 00:20 Our data model is impractical.

Let's see what went wrong and what we can improve. sotm2019-1345-broken-promises-and-technical-difficulties Data Analysis & Data Model Ilya Zverev en People often come to me saying, changesets with huge bounding boxes are impossible to validate. Come on. You know changesets were not meant to group edits by any criteria. Developers look at the data model and derive user experience from it — and it obviously does not work. Every instance of OSM data needs to be preprocessed, converted, filtered, layered, postprocessed and thrown away. We need to stop looking at OSM as a database and start treating it like a map. In this talk I will highlight what's wrong with the current state of API, including both the actual REST API and the server side. Things like topology, notes, GPX traces and stuff: they were coded when the project was small, but the model starts to show its age — and few people know what to do, besides adding more mappers. How come Overpass API became the better API, and what can we learn from it? Changesets should be abandoned by user-facing tools: let's imagine how the mapping, the validation, the undoing of changes would work if we didn't rely on changesets or actually anything API provides. Can we do something to improve data quality right now? Or can we work towards API 0.7, that would help keep the map not only the most complete, but also the most recent? Let's take a step back and imagine how OpenStreetMap should have been working, to make it more fun to work with, while keeping its versatility and simplicity. I have been involved in a couple API 0.7 discussions, made a few tagging proposals and wrote an editor and a change rollback script. That doesn't make me an expert — there are no experts in OpenStreetMap — but it gave me some ideas on how things could be better. Maybe together we will have a clearer path towards the better OpenStreetMap. false https://pretalx.com/sotm2019/talk/V7NUWP/ https://pretalx.com/sotm2019/talk/V7NUWP/feedback/ Hörsaal Ost Talk 2019-09-22T09:30:00+02:00 09:30 00:20 Who benefits from the mapathons: between (over)communication and (over)attribution, critical feedback on the inflation of a form of action oversold in the field of humanitarian action and development aid.

As well as using Overpass queries to retrieve features with data quality issues. sotm2019-1334-bringing-validation-to-users-integrating-quality-assurance-checks-into-map-editors Software Development Clarisse AbalosMatthew Gibb en There is a need for validation in crowdsourced mapping to ensure that the quality of created data meets the community’s agreed upon standards and best practices. The OpenStreetMap community has created many Quality Control (QC) tools (Osmose, KeepRight, OSMLint, etc.) to identify existing errors within OpenStreetMap data, but there has not been as much emphasis on Quality Assurance (QA) tools to prevent issues from being created during the editing process. We are developing methods to introduce these data quality checks in both the iD and JOSM editors to educate mappers and provide immediate feedback while they are mapping. In order to introduce these new tools, we first need to recognize the methods a user typically uses to learn how to contribute to the map properly: - Peruse the many pages on OSM Wiki; - Reach out to community members on mailing lists, forums, or Slack groups; or, - Follow detailed instructions and receive feedback (sometimes untimely) on tasks completed in a focused project (via Tasking Manager or MapRoulette) This process is accepted and works for those who are resourceful and careful, but we wanted to reduce the barrier to entry for new mappers by creating MapRules. MapRules is an interface to create instructions which generate custom presets and validation rules that are then integrated into the existing validation frameworks in JOSM and iD. Contributors are directed on how to map features according to the generated rules and are provided instant feedback if their changeset does not meet the set specification. In addition to using MapRules to create specifications for collecting features, we are creating validation checks specifically for JOSM using MapCSS based on rules found in QC tools like Osmose, KeepRight, and OSMLint. This approach follows the paradigm of checking data before it is committed to the map. This approach is truly for all contributors and users of OSM. It clearly shows its worth to the mappers who are creating new edits, but it also aids validators to quickly identify problems where they may have had to visually and manually inspect each feature or rely on numerous QC tools outside of the editing environment. To further assist in validation and clean up, we have created a series of corresponding Overpass queries that download only the features with identified data issues. Within JOSM, these issues can potentially be resolved by applying automatic fixes on a feature or in bulk. By bringing more validation into the regular mapping workflow, we can help create a better map. false https://pretalx.com/sotm2019/talk/9SSZQH/ https://pretalx.com/sotm2019/talk/9SSZQH/feedback/ Hörsaal Ost Talk 2019-09-22T14:00:00+02:00 14:00 00:20 Indexing OSM data in your PostGIS database for fast spatial queires is not as straight foreward as one migth hope.

This talks explains the basics of working with the SQL database and how it handles geographic data. We'll look at getting OSM data in and out of such a database and what we can do with the data once it is in there. sotm2019-1328-osm-data-processing-with-postgresql-postgis Data Analysis & Data Model Jochen Topf en The PostgreSQL database with the PostGIS extension has always played an important role in the OpenStreetMap project. The main OSM database is a PostgreSQL database, tile rendering is most often done from a PostgreSQL database, data analysis and data transformations using current or historical OSM data can be done with PostgreSQL. But understanding what the database can and can not do isn't always easy. And there are a ton of tools, from osm2pgsql to Imposm to Osmosis to Osmium and beyond that "do things" with OSM and PostgreSQL databases. It can be daunting to understand what they all do and where their place in the larger OSM ecosystem is. This talk is an introduction into some of the concepts of SQL and geographical data in an SQL database as well as a whirlwind tour about uses of PostgreSQL in the OSM context. We'll talk about use cases from rendering, to data analysis to routing. We'll talk about the data models that enable those use cases and the software that implements them. And we'll also talk about where the limits are and what things can better be done outside the database. The audience will walk a way with an idea of how things fit together and how to approach their own projects using PostgreSQL. false https://pretalx.com/sotm2019/talk/K8N3XY/ https://pretalx.com/sotm2019/talk/K8N3XY/feedback/ Hörsaal Ost Talk 2019-09-22T16:30:00+02:00 16:30 00:20 OpenStreetMap's processes are carefully designed to minimize the privacy footprint of the mappers. Nonetheless, the principle that any edit shall be attributable means that some data is still recorded. An overview is given which data is recorded at all and which of it gets available to whom. sotm2019-1234-mapper-s-privacy OSM Basics Roland Olbricht en OpenStreetMap surveys data about places, not about persons. Thus privacy sensitive data in the geodata is very rare and always unwanted. Likewise, the principle of distributing the data allows data consumers of the geodata to stay as anonymous as they want. Mappers can contribute with pseudonyms, although not completely anonymous. However, for both the social features of OpenStreetMap and the purpose of attribution for the edited data it is necessary to collect some privacy related data. A useful starting point to see your own data footprint is the tool HDYC. All the edits you make are grouped into changesets, and the editing software will urge you to add a comment per changeset. As both the edits and the changesets carry dates it is possible to track your activity times. The nature of some edits may suggest local knowledge thus that you actually have been at the mapped places. The kind of edited objects and the mapping standards can be checked by every other contributor as well. Most often, this is simply a reason to be proud of the achievements, but you should know and check before it might get a matter of concern. Using separated accounts for different mapping tasks is often an appropriate solution and well-accepted in the community. OpenStreetMap offers additional ways to interact: you can leave comments on changesets and notes on the map, you can discuss on mailing lists or the forum, or you can answer questions on help. You can write documentation on the wiki. All of these channels have their own rules with regard to how long the data is stored, how it is searchable, and whether you can hide or delete your contributions. The talk presents the data traces of each channel and discusses strategies to get the desired degree of privacy. false https://pretalx.com/sotm2019/talk/XRL7VK/ https://pretalx.com/sotm2019/talk/XRL7VK/feedback/ Hörsaal Ost Talk 2019-09-22T17:00:00+02:00 17:00 00:20 OSM Teams is a software framework for building team-based applications on top of OpenStreetMap. We will present how the software is built, why we think it's a good tool for communities, and how you can integrate your application with the framework. sotm2019-1339-teams-for-openstreetmap Software Development Marc Farra en OpenStreetMap is first and foremost a community platform. A lot of OSM mapping emerges from grassroots collaborations, from local neighborhood communities to large-scale mapping initiatives. These collectives need tools to communicate, collaborate and sustain their combined motivation around mapping, and to that end we present OSM Teams. OSM Teams is a software framework for building team-based applications on top of OpenStreetMap. Development Seed built Teams internally to coordinate mapping projects, and to share tasks and statistics across mapping applications built on top of OSM. By building an authentication and authorization framework on top of the OSM login, we enable a second identity layer for teams that can be shared throughout apps. If adopted by the wider community, OSM Teams would bring structure to organizational editing. Teams would also support individual mappers by empowering them to discover new communities and causes, and to better understand who else is editing the map. With this presentation, I would like to start a technical and community focused conversation about running organizations, teams, and communities using this framework. Specifically the questions I would like to bring to the community are: how does this fit with existing community patterns? How do we reduce complexity for new mappers?

Andal</em> <p>Spatially accurate population distribution maps are essential for disaster risk assessment. Philippines has undergone rapid urbanization and population growth but existing spatial population distribution data across the country is still lacking, thus the dependence for exposure data on Volunteered Geographic Information (VGI) is high. In this study, we explored the use of OpenStreetMap (OSM) data, with the census data of Cavite, Philippines in 2015 from the Philippine Statistics Authority (PSA), in generating population distribution maps for Cavite. The results showed that OSM database can be used to produce population distribution model using GIS. However, using OSM data might have some limitations as completeness and positional accuracy of the data can vary across different study areas. Previous studies have found that the completeness of data in populated or urban areas are better compared to rural areas.

Even if you are not on a Chapter but are a local organizer, feel free to join! Local Chapters are not-for-profit legal entities to be established within different territories around the world which can act as official local representatives of the Foundation when dealing with local government, business and media. OSMF is an organisation is incorporated in Great Britain. It wants to support the OpenStreetMap project (and other free mapping projects, where applicable) in the whole world. But it can't be everywhere and reach everybody, especially people speaking languages other than English. Local chapters can extend the reach of OSMF, foster local communities, help with legal and financial matters in their respective countries and generally promote OSM in their local areas. Some of these goals (such as handling financial matters or providing a point of contact for government or media) can also be handled by totally independent organisations supporting OSM but not associated with OSMF in any way.

Nowadays, popularity of OSM has been spread all over the world. Moreover, based on development of OSM itself, many parties has been used it in any sectors including routing services. However, road mapping is not as popular as POI Mapping eventhough road data is also important as polygon or buildings in OpenStreetMap. So far, OSM mappers mostly focus on mapping public facilities and POI to complete their area in OpenStreetMap. Thus, this workshop will be focused on road mapping in JOSM using turn restriction where the participants can learn more about mapping road in advanced way. Moreover, this workshop goal is to improve more knowledge around OSM mappers community that can lead to improving Data Quality in OSM especially roads.

First talk part is about the new support of MapCSS rules in Osmose-QA. MapCSS language was primarily designed as way to style map objects, it look like the web styling language CSS. The base of MapCSS is to use selectors to filter objects. JOSM already use it for map styling and validator. This new implementation of MapCSS in Osmose-QA allows to write rules more easily. It also allow to reuse JOSM validator rules set. Next step would be to run Osmose rules in JOSM. It’s a great opportunity to share rules across tools and projects. But come the question on how to share and manage this rules while considering tools particularities. Second talk part is on external data comparison (aka conflation) with OpenStreetMap. It permits to point issues and evaluate the coverage, lastly it allows fixing and integration into OpenStreetMap. The more we wait, the more there is OpenData sets available.

Furthermore, specific needs of various person groups will also have to be considered facing variable data quality. sotm2019-1265-routing-for-humans Software Development Sebastian Ritterbusch en People primarily move on sidewalks, but this is hardly taken into account in generally available routing solutions. The OpenStreetMap provides probably the most comprehensive digital path network for pedestrians, which had been largely unused in its actual depth of detail so far. Through an efficient and transparent topological extension of the path network, more accurate routes for pedestrians and other means of transportation can now be determined, revealing hitherto unnoticed mapping problems and an undesirable previous focus on automotive mobility. As part of the TERRAIN project, an exemplary publicly available navigation system for blind persons was developed that demonstrates the special challenges of human locomotion based on the OpenStreetMap. Challenges and robust solutions concerning data quality, micro-mapping and transition areas, regional OSM semantics versus mapper interpretations, and path bundling are presented. A large part of the footpaths in the OpenStreetMap are listed in the form of annotations as sidewalks. This well-proven procedure enables a low-maintenance, robust and high coverage of the footpath network. However, a presentation with many paths inevitably leads to contradictions due to path bundling, which requires a more elaborate micro mapping, which is often not noticed by mappers up to now, and can now be shown clearly. But also regional micro mapping can lead to unexpected complications in addition to the increased effort, since a multitude of connection problems can occur which have to be considered. In addition, there are a large number of requirement profiles for children, adults, the disabled or the elderly who travel on foot, in wheelchairs or on scooters.

Working with Age UK and Disability Stockport, the project crowdsourced data about accessibility issues in Stockport, drawing on the lived experiences of people with mobility impairments to supplement data already available to the council. The municipal environment often includes barriers that exclude people with restricted mobility. These barriers may be the result of natural topography, historic planning, deterioration of the urban environment or planned and unplanned maintenance. Some of the barriers may not be known to the local authority. People with mobility impairments are on the frontline when it comes to negotiating these obstacles, and often have their own knowledge and strategies in negotiating and circumventing them. This is a resource that could be invaluable in helping others who face similar challenges, as well as helping local authorities identify where interventions need to be made. One of the aims of Mapping Mobility Stockport was to begin to map and find ways to continue to share these strategies. Using our Joy Diversion format as a basis, Open Data Manchester co-designed and ran a series of workshops with Age UK and Disability Stockport, which brought together different techniques and mobility strategies contained within the local community to enable people of all abilities to explore and map their environment. We used large, hi-resolution maps of Stockport to scribble on and sketch out routes, before taking to the streets to document, photograph and map the kind of things that these communities come up against on a daily basis. This information was then added to Stockport Council’s mapping system and Open Street Map, helping create a mobility map of Stockport. This talk will explore how we collected this data, sharing some of the findings and insights from the project, such as how what is useful for one disability can be problematic for another (such as tactile paving, which is useful for those with visual impairments but can be problematic for a wheelchair user). The talk will also explore the difficulties that arose out of this when categorising and tagging these features, and question whether more needs to be done in terms of mapping the streets and sidewalk. false https://pretalx.com/sotm2019/talk/9FQVUT/ https://pretalx.com/sotm2019/talk/9FQVUT/feedback/ Großer Hörsaal Extended Talk 2019-09-23T11:30:00+02:00 11:30 00:40 We map because we care to represent the world. Yet maps are never "true", they are shaped by their creators and their circumstances. Map-making is world-making: maps by different authors can give access to different worlds. So how can we make, share, and use maps that are created _by_ these worlds, and not just by a privileged few? How can vulnerable communities influence how they’re represented and affected by our maps? sotm2019-1287-caretography-mapping-difficult-issues-with-openstreetmap-during-difficult-times Community and Foundation /media/sotm2019/images/F9D8QG/caretography_thumbnail.jpg David GarciaMartin Dittus en The popular view is that mapping the world is just an act of reflecting reality and reflecting nature. People rely on map-makers like us to show them the “true” spatial arrangement of the world. And yet, making a map also involves making assumptions, omissions, additions, and generalisations, and it feeds on our training, experiences, and personal perspectives as map-makers. A map is never really “true”, it is shaped by the hands of its creators, and it is always also a product of chance and its circumstances of making, sharing, and use. It can be said that map-making is world-making: maps shape our understanding of the world, and inform our actions in the world, and a map by a different author can give access to a different world. So how do we create a map of the world that is created _by_ the world, and not just by a privileged few? To fully appreciate the complexity of this challenge we need to extend our understanding of what counts as maps and mapping, and why. In order to understand our responsibility as map-makers, we need to become both _critical_ and _caring_ cartographers. This shift in perspectives and attitudes can help us understand better what can happen when our everyday mapping practice connects with real-world circumstances. It may also help us become more responsible as the volunteer workers of OSM. David and Martin will guide you through a careful and caring consideration of OSM based on personal experiences, and talk about the responsibilities we carry as we map and make the world during difficult times. For example, we may encounter circumstances where the OpenStreetMap approach to openness brings complications. Can the communities represented on the platform make decisions about how they’re being written about? Indigenous communities around the world regard their land as sacred and don’t want it to be mapped. Should we as a global community know when not to map? There are circumstances where the act of mapping itself can bring danger to the mapper. Do we have the right methods to assess such risks? What support can we offer those who take them? If we don’t, whose hand gets to shape the map instead? And what does all of this this mean for a do-ocracy, where decisions emerge slowly and can often contradict each other? Or to put it even more broadly, how can we diversify, democratise, denaturalise, and decolonise open mapping? Who cares, you ask? David and Martin have participated in the OSM ecosystem as mappers, researchers, and organisers, and have been involved in the Humanitarian OpenStreetMap Team and other global mapping initiatives. Based on their personal experiences they will introduce you to a careful and caring consideration of OpenStreetMap cartography, and talk about the responsibilities we carry as we map the world. They ask you to consider that maps are not _universal_, and that even in OpenStreetMap many different maps and mappings are possible. They propose that a better map may be a _pluriversal_ one, where many different perspectives can coexist. Can OpenStreetMap accommodate this? Which practices can help us produce maps that represent the world more equitably? More importantly, if we think that mapping can make a difference in a time of global precarity, inequalities, climate catastrophe, and mass extinction, then they ask _you_ to care. false https://pretalx.com/sotm2019/talk/F9D8QG/ https://pretalx.com/sotm2019/talk/F9D8QG/feedback/ Großer Hörsaal Talk 2019-09-23T12:30:00+02:00 12:30 00:20 In many regions of the world, a population’s access to essential services is unduly constrained by a lack of proper infrastructure. By performing accessibility analysis using OSM data, we can understand how route infrastructure impacts access to essential services and use that information to inform an intervention. This talk explores accessibility analysis performed to understand the impact of footbridge construction in eSwatini and introduces a python framework enabling users to perform similar analysis. sotm2019-1364-access-to-prosperity-quantifying-infrastructure-impact-with-osm Software Development /media/sotm2019/images/7FBMMM/access.png Davey Lovin en Bridges over rivers are fundamental pieces of human infrastructure which enable safe crossings for the populations who use them. However, many rural regions of the world lack these critical bridges, and as a result, access to essential services is restricted for millions of people. In pursuit of tackling poverty caused by rural isolation, we have begun experimenting using remote analysis techniques to quantify bridge need and impact. To these ends, accessibility analyses using OSM and other data have proven to be extremely valuable. By comparing a population’s baseline accessibility to its access in scenarios such as a flood or post bridge construction, one can better understand the transportation dynamics of a region and even estimate the number of people that would be impacted with a bridge construction, for example. During the course of running various accessibility models, a python framework tebetebe was built around OSRM [Open Source Routing Machine] which simplifies the process of running different scenarios. This framework is built with footbridges in mind but is generalized so it may be applied to other applications. This talk explores the accessibility analysis process, its caveats and results achieved in the Kingdom of eSwatini.

Since 2016, travelers can explore all 380 railway stations of the Greater Paris area through interactive maps deployed on their web site and on a mobile app. Browsing a map is good, but not good enough when you are lost inside a complex, multilevel, indoor (and/or outdoor) environment. It gets worse for someone in a wheelchair, elderly people, or anyone coming back from a family trip with more luggage than your hands could carry. What if we could bring pedestrian routing and navigation services to help travelers find their way inside and around railway stations? Could we do it using OSM data? This is the challenge SNCF has been trying to tackle for the past few months. Together with Jawg Maps and Carto’Cité, they held a detailed mapping campaign on 83 stations and developed a dedicated routing engine. This engine can seamlessly navigate indoors and outdoors, and achieves routing through open spaces such as pedestrian areas and station halls. This talk exposes the challenges we faced. It focuses on the data structure and the algorithmic strategies that have been defined to provide a robust navigation service, and its ability to handle the great diversity of railway stations.

Some of it, such as buildings mapped using the [Simple 3D Buildings](https://wiki.openstreetmap.org/wiki/Simple_3D_Buildings) tagging convention, is intended primarily for 3D use cases. Other feature classes, such as roads and railways, urban infrastructure, or landuse information, aren't usually mapped with 3D in mind, but are nevertheless essential ingredients of a 3D world. In either case, unlocking the full potential of OSM data and converting it into a representation that's suitable for typical use cases in the domain of 3D rendering requires specialized software tools. [OSM2World](http://osm2world.org/) is one of these tools. Fully open source, it can be used to export 3D data for modelling software, animations, and games, as a library in other programs, and as an interactive map on the web. Until recently, however, the lack of a powerful 3d rendering solution for the web put constraints on the features available without a local installation of the software. Today, the WebGL standard allows real-time 3D rendering in all major browsers. A new web frontend for OSM2World builds on these capabilities to allow users to explore the world in 3D, based entirely on open data.

The purpose of OpenDatathon's activities is different for each organizing group. Among the purposes, cases aimed at local information distribution are worth noting. It edits information on OSM and Wikipedia and uses it for the development of the local community. Because Civic Tech communities and local government organizations are often interested in it. For example, the library is collecting material about the history of the area. Writing on Wikipedia using them is important to them. The number of OpenDatathon hosted by the library is increasing. We also frequently support events organized by other organizations. That way, they can manage the event without having direct contact with OSM and Wikipedia experts. In addition, it is possible for people of various motivations to participate by incorporating the fun of walking around town. In order to edit OSM and Wikipedia, We are looking for historical or important topics in the local area. In addition, we may hold multiple events as a series of historical themes. We are planning a story in mapping, and creating a motivation for people to participate by incorporating a specific feature.

Until recently there was a lot of goverment data but it was not available for use, after few requests for the right of data reuse now we have data available for OpenStreetMap use. With goverment institutions starting to grant us the rights to use their aerial imagery, there are privat companies starting to do so too. We acquired not only raster data but started to acquire goverment vector data which is great news. There are a lot of plans, we are moving forward every day one step at a time, but there is not enough of us to do it all ... false https://pretalx.com/sotm2019/talk/ADYMVF/ https://pretalx.com/sotm2019/talk/ADYMVF/feedback/ Kleiner Hörsaal Panel 2019-09-23T11:30:00+02:00 11:30 01:00 New processes to agree on tagging suggestions and their interaction with the editing software available on openstreetmap.org sotm2019-2578-new-processes-to-agree-on-tagging-suggestions-and-their-interaction-with-the-editing-software-available-on-openstreetmap-org Community and Foundation Roland Olbricht en I instead suggest to collect ideas with deadline 1st of September. I commit to present my ideas then and invite everyone to do so as well (on this list, the wiki, or the forum, other channels if known and openly available). This gives people not attending the conference better chances to get involved. That preparation ensures that we end up with one (or more) deliverables that can be worked on. This is also the reason to prefer the BoF over a panel discussion. I am unable to organize a panel discussion in a way such that it produces a deliverable. Some keywords to foster hope that there is a way forward: - Changeset discussions as a social feature have widespread acclaim - The "Any-Tag-You-Like" principle accompanies and serves OpenStreetMap since more than a decade - IETF's "Rough consensus" (RFC7282) has built the internet - many tools already facilitate to make evidence based decisions, e.g. Taginfo in general and Taginfo's [list of tag usage](https://taginfo.openstreetmap.org/keys/highway#projects) false https://pretalx.com/sotm2019/talk/PPTHFQ/ https://pretalx.com/sotm2019/talk/PPTHFQ/feedback/ Kleiner Hörsaal Panel 2019-09-23T14:00:00+02:00 14:00 01:30 Most of the existing attribution guidance for OSM derived works dates back to 2012 and was written before or around the change of the OSM licence to the ODbL.

While OSM and Wikipedia, the more well-known sister project of Wikidata, are often compared with each other (e.g., “OSM is like Wikipedia for maps”), OSM and Wikidata are actually even more similar. OSM has things like nodes, ways, relations, tags, keys, and values, while Wikidata has similar concepts like items, statements, properties, values, and qualifiers. Data modeling discussions on the OSM tagging mailing list are often as passionate as similar discussions on the Wikidata project chat page. Since Wikidata was created in 2012, there have been plenty of links, projects, and collaborations between the two volunteer communities. This includes data links (such as OSM's `wikidata=*` tag and Wikidata's P402 or "OSM relation ID" property), to projects like Sophox which is a SPARQL endpoint that provides access to OSM and Wikidata, and to things like installing the Wikibase extension—the software that powers Wikidata—to the OSM Wiki in order to provide structured data for OSM keys and tags. This workshop is intended to provide participants with an introduction to Wikidata and how to contribute to it, how OSM and Wikidata compare and contrast with each other, and examples of projects or initiatives that combine OSM and Wikidata. The workshop will also teach participants how to use an online tool that lets mappers generate a list of candidate matches between OSM and Wikidata within a specified a place or region, which are then reviewed by the mapper and saved to OSM as wikidata=* tags. The final part of the workshop is intended to be a discussion of ways the two open communities can collaborate with each other including tackling the issues that prevent further collaborations (such as license compatibility). false https://pretalx.com/sotm2019/talk/GUUUYW/ https://pretalx.com/sotm2019/talk/GUUUYW/feedback/ Mathematikon C Workshop 2019-09-23T11:30:00+02:00 11:30 01:00 **Experience Mapper Only**. Creating presets sometimes become a hassle if you don't have experience reading XML language. There is a simple method to create presets in a simple way using JOSM plugin. This workshop will teach about how to create a presets using JOSM. Note: **This workshop for experience mapper only** sotm2019-1360-custom-presets-creation-using-josm Mapping Harry Mahardhika Machmud en Presets is the most important part when creating an object in OpenStreetMap. Without presets, all the objects will not be rendered in OpenStreetMap site because it doesn't have any attribute on it. Adding presets is one way to add more information in JOSM. Sometimes JOSM only has predefined presets which might give us challenges if we want to add another additional information, such as building structures or building level, because we need to add the key and value through *add* button in the right side of JOSM attribute panel. The solution for this problem is we can create a custom presets by using the text editor in XML language. But, this can become a hassle if you don't have experience reading XML language. There is a simple method to create presets in a simple way using JOSM plugin. This workshop will teach about how to create a presets using JOSM. This workshop will talk about things you need to know before creating a presets, exploring Wiki Map Features, and create a simple presets in JOSM. If you want to attend this talks, please make sure that you already have an experience to contribute in OpenStreetMap. Experience in key and value also good if you want to join the workshop. false https://pretalx.com/sotm2019/talk/QHTNEY/ https://pretalx.com/sotm2019/talk/QHTNEY/feedback/ Mathematikon C Workshop 2019-09-23T14:00:00+02:00 14:00 01:00 In this workshop, OSM mappers and software developers Beata and Laura will help you get started adding the more than 2 million roads that are missing from OSM according to ImproveOSM, the global open dataset that compares actual car trips with OSM data. sotm2019-1308-improveosm-missingroads-workshop Mapping Beata Tautan-JancsoDeleted User en In this workshop, OSM mappers and software developers Beata and Laura will help you get started adding the more than 2 million roads that are missing from OSM according to ImproveOSM, the global open dataset that compares actual car trips with OSM data. In the first part, we will show you what ImproveOSM is, how it is made, what the data looks like and how you can use it. In the second part, we will get our laptops out and do some mapping using the JOSM ImproveOSM plugin. We will have a leaderboard for the event and mapping prizes as well! The workshop assumes you have some experience using JOSM. Bring a laptop! Beata Tautan-Jancso is a java developer and leads the Telenav JOSM team. She works on implementing different tools that expose the results of the Telenav OSM data analysis team. Laura Dumitru is a java developer that works on services and JOSM plugins that aid in the process of visualizing and validating the results of the data analysis. Telenav has been a user of and contributor to OpenStreetMap since 2013, when we launched the Scout mobile navigation app powered by OSM data. Even before that, Skobbler, now part of Telenav, has been part of the OSM community for much longer. Our contributions to OSM include tools like OpenStreetCam, MapRoulette, MapDust, a number of JOSM plugins to help mappers, as well as ImproveOSM open data to help mappers find missing roads, one-ways and turn restrictions. Since 2015, The Telenav map team has improved OSM by adding thousands of new roads, turn restrictions, and detectable road signs in the U.S. and Canada. false https://pretalx.com/sotm2019/talk/RUJWP8/ https://pretalx.com/sotm2019/talk/RUJWP8/feedback/
