Contact the OpenStreetMap Foundation to start a collaboration
OpenStreetMap is a world project to create and mantain a world Map open and free with the same collaborative principle as Wikipedia.
In the OSM Map everyone can add or update any information (amenities, street names or speed limits)
The Walkscore calculation should be easy if OSM DB will be used ... more

YES! Well, ideally anyway. OSM is not the very best map out there right now for accuracy of points of interest, which is what Walk Score really measures. Google's is definitely pretty great, because it combines supplied POIs with user-updating. But the OSM has the potential to have so much more info, such as bike paths, sidewalks, crosswalks, pedestrian trails, etc, that nearly all online maps lack.
