Unlike outdoor GPS navigation, indoor navigation is still rare and expanding at a slow pace.

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 \u201cSimple Indoor Tagging\u201d 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.

Started in 2017, \u201cIs OSM up-to-date?\u201d 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).
\n\n## Deriviste - Click and Go Photo Mapping\nChristopher Beddow\nThere 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?

You can change it for the better: start a blog, record a podcast, tweet something. Here I will share my experience at keeping OSM community informed.
\n\n## Enhancing OSM with missing roads\nBeata Tautan-Jancso\nImproveOSM is a powerful tool that detects and highlights areas in OSM where roads, one-way attributes, and turn restrictions are missing from the map. The first version of the JOSM plugin was released in 2015. Since then, the community has improved almost 200.000 areas with missing roads.

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.\nThe 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.\nRecent internal analysis estimates that NT look after a network of 20,000km of footpaths which comprises both legally designated \u2018Public Rights of Way\u2019 (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.\nThe Paths Project is capturing a digital inventory of paths on National Trust in order to:\n \u2022 Demonstrate how NT are fulfilling our core purpose of providing access to special places.\n \u2022 Improve asset management including maintenance and enhancement of the path network,\n \u2022 Provide a digital base for trail curation and enhanced visitor experiences.\nA review of options concluded that the OpenStreetMap would be the best system for management of the National Trust Paths Inventory.

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.\nIn 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.\nThe 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.\u00a0 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.\nThe 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.\nWhilst this project is still to be completed, other potential asset types that could be managed in OSM in this way have been identified.\nThe true value of a UK wide paths inventory will only be realised by having a comprehensive, authoritative and trusted dataset.

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.", "description": "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.\n\nHowever, 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.\n\nAt 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.\n\nFor 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.\n\nThe 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.\n\nThe bicycle tagging page on OSM provides a perfect demonstration of the current problem:\nhttps://wiki.openstreetmap.org/wiki/Bicycle\nIt 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.\n\nCycleways 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.\n\nAnother 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:\nhttps://www.openstreetmap.org/#map=17/48.87391/2.29536\n\nThis 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.

As well as using Overpass queries to retrieve features with data quality issues.", "description": "There is a need for validation in crowdsourced mapping to ensure that the quality of created data meets the community\u2019s 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.\n\nIn 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:\n- Peruse the many pages on OSM Wiki;\n- Reach out to community members on mailing lists, forums, or Slack groups; or,\n- Follow detailed instructions and receive feedback (sometimes untimely) on tasks completed in a focused project (via Tasking Manager or MapRoulette)\n\nThis 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.\n\nIn 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.\n\nThis approach is truly for all contributors and users of OSM.

\n\n## Using OpenStreetMap Building Footprints Data for Population Distribution Model: A Case Study in Cavite, Philippines\nDinnah Feye H. Andal\nSpatially 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. The model can be best used when the quality of OSM data such as its completeness, consistency, accuracy, validity, and timeliness is high.

\nDuring the work we faced various difficulties, so we will explain what these difficulties were and how we tried to build at least something. We will also cover how OSM users can help us, and whether it is possible and how long it will take to improve the data.
\nLastly, we will present our results and plans, namely, what was our most significant success and how we want to build an editor for public transport..
\nWe launched the function at the beginning of the year, and throughout the year we tested it, supplemented it with new conditions for building a route and tried to take into account all possible conditions for building routes. Although the data in the OSM have not proved to be always correct, everything can be fixed by the community.

Data modeling discussions on the OSM tagging mailing list are often as passionate as similar discussions on the Wikidata project chat page.

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\u2014the software that powers Wikidata\u2014to the OSM Wiki in order to provide structured data for OSM keys and tags.\n\nThis 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.
