a powerful web-based mapping & visualization tool based on Google Maps, capable of displaying all sorts of geographic data. gCensus is an effort to make geographic data freely and easily accessible to the public, without the need for expensive GIS software packages. users can freely pan, rotate, & zoom into & out of maps, change the ground angle or alter the transparency of different areas to satellite imagery.
update: gCensus & Juice Analytics are 2 separate projects, but very similar. thnkx commenters for catching the confusing mistake.
