The original ROS user map [1][2] worked well initially, but succumbed to a bit of vandalism. As it turns out, University of Arizona is not off the shore of Puerto Rico. I have engineered a new solution with tools ROS users are more familiar with, which you can view here:

The map is generated from code and data in a open source repository[3]. The map is far from complete. I cleaned up some of the data, but had to work with the information I had at hand. I encourage *all* members of the community to add/edit their location on the map. Requests for features, additional information, pull requests should all be handled in the normal githubby way. 

Cheers,
David!!

P.S. Have you updated the map yet?
