Wheelmap

"Wheelmap is an open and free online map for wheelchair-accessible places. It empowers users to share and access information on the wheelchair-accessibility of public places. Like with Wikipedia, everyone can participate by tagging places. Places that are not yet marked have a grey tag and can be quickly and easily marked by everyone. The crowd sourced information is free, easy to understand and can be shared with everyone. Moreover, logged in users can upload photos to places or write comments to further describe the wheelchair accessibility of a place. This additional information makes it easy for mobility-impaired users to determine whether they can access the place or not. Wheelmap.org is a global tool that can be used by everyone everywhere. It is available on the internet and as an app for iPhone and Android"
