Programme

State of the Map 2026 will take place from August 28-30, 2026 in Paris. We created an exciting programme with you—the OpenStreetMap community. For the duration of the conference, there will be rooms set aside for breakout sessions, booked by groups of mutual interest or used without prior planning.

The programme below is still in a preliminary state: talks might still be shifted around by the programme committee and some remaining talks as well as the details of the academic track will be added soon.

Self organized sessions

Besides the main programme of SotM we offer space for self-organized sessions for discussions about topics that well placed in smaller rounds. The only requirement that we have to your topic is that it has to be related to OpenStreetMap. For on-site self-organized sessions, we will set up a white board at the conference venue to reserve a time slot and room. The only requirements we have is that the participants have a conference ticket which grants them access to the conference platform that we use and that they abide to the conference's Code of Conduct.
