What if you could project US Census data on a 3D map of the country? That’s what you get in this Google Earth mashup from Imran Haque, a PhD comp-sci student at Stanford. “gCensus is an effort to make geographic data freely and easily accessible to the public, without the need for expensive GIS software packages. With Google’s excellent free mapping program Google Earth, you can use this site to visualize a wide variety of data best displayed on a map. Currently, only the US Census 2000’s Summary File 1 (displaying population characteristics such as race and age) is available for mapping. I hope to have additional data sets, such as income (Summary File 2) and voting statistics, available soon.”
