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.

The Fédération des pros d’OpenStreetMap (FPOSM) is the French non‑profit organization that unites companies and professionals whose services and tools are built on OpenStreetMap, and who are committed to keeping OpenStreetMap a healthy digital commons.

Launched during State-of-the-Map France 2023, the FPOSM now gathers 28 French companies with expertise in creating, using, enhancing and ensuring the quality of OSM data on topics such as : mobility, routing and accessibility, infrastructures and power grids, urban planning, food and agriculture, tourism, local business, community outreach and more. Members also develop and maintain software around OpenStreetMap, such as Clearance, Podoma, LeBonTag, GridInspector.

The FPOSM is the worldwide most advanced structured federation of OSM professionals directly coming from and complementary to the volunteer community and local chapters.

We will share how and why FPOSM was created, and how we are committed to preserve OpenStreetMap’s ethos and guidelines.

We will also talk about the FPOSM’s collective work:

• OSM advocacy towards public authorities
• The practical booklet « Everything you need to know about the ODbL licence, available in French and English.
• The guide « OpenStreetMap and Territories », which brings together a wide range of testimonials from French public sector stakeholders who have used OSM across their territories.
• The organization of events like « OpenStreetMap & territoires » that connect professionals and public actors.

We’ll wrap up with what we’ve learned, what challenges we are facing, and some ideas for starting similar groups elsewhere, so professional ecosystems grow alongside and actively support local OSM communities.
