SimpleGeo

Simply the easiest way to use location. SimpleGeo was built with developers in mind. Why spend months building and scaling location infrastructure when you can be up and running in minutes? Store and scale your own location data with our Storage Engine, perform complex geospatial and temporal queries via a single HTTP request; the technology was built using proprietary, scalable grid technology based on Google's BigTable and Amazon's Dynamo. Multi-homed and fully redundant across three data centers on two continents!
