Many cities have started to create open data websites to post their collected geospacial data. These sites usually allow bulk download of their datasets in standard machine-processable file formats, which is key. Some have visualizations of the data too, though this is a secondary feature to open data. These sites are either created by the city, or they use certain vendors to provide easy, out-of-the-box solutions for formatting, opening, and mapping their raw data.
UPDATE – Oct 28, 2013
Since creating this post a number of other organizations have started keeping a list of cities, counties, and states with open data portals. As such I’m not going to update this page any more. Please visit the following 3 pages to see a list and either edit their pages or connact them to have them add new ones.
