Meet an OpenStreetMapper

Gregory Marler

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.

Spatial indexes for OSM in PostGIS

Felix Kunde

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.

Using OSMCha to understand bad edits

Andrey Golovin, Wille Marcel Lima Malheiro

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!

Updating our attribution guidelines

16:30

Simon Poole

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.

17:00

Is the OSM data model creaking?

Martin Lucas-Smith

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.

David Garcia, Martin Dittus

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?
