One region. 40,000 bus stops. An OSM map at every one.

Producing a single map targeted at public transport users might be straightforward... but what if you had to produce a hundred? Or a thousand? Or 35,000..? All of them adhering to high standards of quality and consistency, while also ensuring they are up-to-date, across Europe's most extensive public transport network?

And what if open data could play a vital role?

Discover how « plans de proximité » (location-specific area maps) are designed, produced and maintained for bus and tram stops across the entire Paris region.


T-Kartor is a Swedish cartographic agency, behind some of the best known pedestrian mapping systems - Legible London, WalkNYC, Toronto TO360. We've been working with Île-de-France Mobilités on a production system for « plans de proximité », a vital, stop-specific, map-based aid to the millions of users of across the Paris region's transport network.

This talk will be a speed-run through this project, from context to build to deployment to maintenance. We'll dive into our process, from editing OSM data to delivering print-ready files to transport operators, touching on dozens of in-between steps, and reflecting on lessons learned and where we may go next.

Throughout this effort, T-Kartor has been accompanied by proud (and local!) OSM stalwarts Jungle Bus.

We still believe in printed maps! And, hopefully, by the end of our talk, so will you!
