The Wheelmap is based on geodata from OpenStreetMap (OSM). OpenStreetMap is a free worldwide map, created by people like you. It's like Wikipedia for maps. To be able to edit places or to create new ones you need an OpenStreetMap account and must be logged in with it.
With your knowledge about wheelchair accessible places you can help people with physical impairments to plan their daily lives better. Furthermore, this will help make OpenStreetMap more detailed.
Thank you very much for your support!
