This session provides an entertaining yet informative introduction into everything you need to know about OpenStreetMap.

The PT_Assistant plugin has been developed over the past 3 summers as a GSoC project. 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.

How useful are map features automatically extracted from street-level images? Can they be trusted? These are some of the questions we tried to answer through community campaigns and student-led research in 2019. We will share some of these lessons and elicit a broader discussion on the methods that can be used to turn automatically extracted features into useful OpenStreetMap data.

Building forward from our work presented last year at State of the Map, we have created a system to assist mappers via machine learned models. In addition, we have built an automated ingestion framework for OSM data at scale that allows us to selectively update parts of the map instead of doing a full snapshot change.

Deep learning methods for feature extraction using computer vision are giving concrete results. This talk provides an overview of feature detection from satellite imagery and how machine learning can provide a seamless mapping experience for mappers, allowing them to utilize their knowledge to enrich maps further.

It’s been more than a year since we at Grab incorporated OpenStreetMap into our ecosystem and we have come a long way since then. This talk will focus on our learning journey, our tools, the challenges and our experiences working in the South East Asia region and the vibrant OpenStreetMap communities here.

Over the last few months, we’ve been building an offline first field mapping tool for the OpenStreetMap ecosystem called Observe. Observe makes field surveying, and verification easy for mappers, and works on iOS and Android. My talk will cover how Observe integrates with mapping workflows and helps improve OSM data from the field. I'll also touch upon fundamentals of building Observe and our assumptions on field mapping.

What is an OSMF working group, what does the membership working group in particular do, and how can you improve the experience of an OSMF membership.

Get to know the Board and the Working Groups. Together, we run the OSMF. Let's use the SotM to have a real face to face meeting. The public is invited to join the conversation too.

During this session I’ll share some tips & tools for new comers to start making their first edits on OpenStreetMap. I’ll do so by explaining the mapping concepts, process, the use of editors, and will continue with the practicing part. By explaining this process , I aim to make it easier for new contributors to get started with editing and will show some daily life examples to illustrate the importance of even the smallest contributions.

We've learnt about many projects and clever systems that run OpenStreetMap possible, but it's the individuals that are most valuable in what we do. Settle down in your seats as Gregory introduces you to a selection of OSMers and informally chats to them about their involvement. When, how, and why did they join OSM? What do they do in the project? Has that changed? What's their favourite map tag? All these questions and more will potentially be asked.

Services that provide money advice, access to food provision, digital access and community support are key to supporting those facing poverty. “Our Falkirk” is a simple mapping platform for service discovery that allows enriched OSM data to be easily described, mapped and shared through the concept of data ‘themes’.

Indexing OSM data in your PostGIS database for fast spatial queires is not as straight foreward as one migth hope. And with each release of PostgreSQL / PostGIS there are more options to try out. This talk will explain different spatial indexing concepts and best practices in PostGIS and present some benchmarking results.

Protecting OpenStreetMap is a continuous process performed by Mapbox to secure maps from displaying erroneous edits. Any edits that raise suspicion are flagged in OSMCha, an open service that allows to check low-quality changes that are made by the members of the OSM project in a shared database. This not only helps to report our findings to the community but examine them in aggregate and draw conclusions to improve our data quality processes.

JOSM is almost as old as OSM but few people really know what it takes to maintain your preferred editor.
We'll present the development model of JOSM and who's part of its active community: developers, translators, testers, plugin authors, end users, sponsors, etc.
We'll talk about the project difficulties, the major achievements made in the past years, what work is currently in progress and what will happen in the near future!

We are working to map all the solar panels (photovoltaic, "PV") in the world. Why? The data can be used directly to reduce carbon emissions from power generation. We will share our experiences of surveying, aerial mapping and machine vision to find all the hundreds of thousands of solar panels in our countries.

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.

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.

Using JOSM Plugin to mapping road in advanced way and improving data quality in OpenStreetMap.

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.

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 there have been relevant discussions and rulings by the OSMF LWG (Licence Working Group) since then, there is no easy way to find it in one document. The LWG has undertaken to review the existing guidance and update it where necessary and is now asking for community input.

The OSM data model has facilitated rapid growth of community-created geodata which third parties can build on. 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.

In early 2019, Open Data Manchester teamed up with Stockport council, Disability Stockport
and Age UK Stockport to crowdsource data around mobility and accessibility in the town centre. This talk will cover the mapping methodology, findings, difficulties and solutions, as well as suggesting ways in which we can better map for these communities, making the data collected for OSM more inclusive and accessible for all.

State of OpenStreetMap in Croatia. Community that builds the data, and community that uses the data.

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?
