Does google maps conform with the w3c accessibility recommendations(A,AA,AAA)?
You can test by yourself using some online validators :
- a complete list of accessibility validators by the w3c : http://www.w3.org/WAI/ER/tools/complete.html
- a Gmaps accessibility check result http://wave.webaim.org/report?url=http%3A%2F%2Fgoo.gl%2Fmaps%2FIEXW&js=2 (result)
I guess some improvements could be done, but by nature rendering and displaying map has some limitations regarding accessibility.
The embedded Google maps are not accessible to sighted keyboard-only users, nor to non-visual screen reader users (particularly this second group). The actual Google Maps site maps are more accessible. Your best bet is to provide street addresses and zip codes in text to allow Google Map search. You could also create links to the specific search on Google Maps in a span or div and hide them visually with CSS clipping.
Simply running an automated accessibility testing tool won't provide you with the full picture, since only a subset of the WCAG success criteria can be tested with automated tools.
