Looks nifty. Probably uses SAR (Synthetic Aperture Radar) or something similar.
Either way, from their own brochure, they don't use satellites, they use aerial platforms (planes)
As far as Colorado Springs goes... there are 4 Air Force bases and 1 giant Army base in town. It's a nearly perfect target for terrorists in that regard, but I'm not sure why roof estimator imagery would be restricted.
