The Great Firewall just got a little taller. Starting next month, all geo data about China must be stored on servers inside China. This is much more that a snub of Google for moving its data out of the mainland, it is a power play aimed at controlling a type of data about which China is very sensitive, as shown in recent border disputes, and the discovery of secret military installations.

Map enthusiasts might enjoy The Geography Network, a new venture from ESRI, vendor of the most used GIS system. The site includes an in-browser viewer, so you don't need to own any ESRI products to see the free data. If you do, though, the data's yours for the downloading. They've already got the latest TIGER census maps as well as a ton of maps and information from around the globe. They hope to create a central location for GIS data sharing, and they're off to a good start.
