Locations
Geographic information is such a wide ield that it probably deserves its own guide, but here I'm
going to focus on the most useful and accessible data sources I've found. All of these take some
kind of geographic location, either a place name, an address, or latitude/longitude coordinates,
and return additional information about that area.
SimpleGeo
This is a compendium of useful geographic data, with a simple REST interface to access it. You
can use the Context API to get additional information about a location and Places to ind points
of interest nearby. There are no rate limits , but you do have to get an API key and use OAuth to
authenticate your calls:
