If you're in the UK you might want to check out https://wheelmap.org

It is also crowd sourced, so coverage varies. Where I am in Bath, there has been a big push to get much of the city mapped (it's a pretty wheelchair-innacessible city), and apparantly it's been quite sucessful. The mapping project is run by the Bath:Hacked group, they have a project page at https://accessiblebath.org/

I'm happy to put you in touch with some of the people involved if you wanted to try and get something like that going where yoou live. I'm sure they'd be happy to help.
