How do you get the country/state/region/city/state/zip/postal from GPS coordinates?

I have GPS coordinates on all of my photos. I want to include tags/IPTC data for the city, state, zip, etc.. However all I have is the GPS coordinates. How can I take these and get 开发者_StackOverflowmeaningful info in an automated fashion (I have thousands upon thousands of photos, so typing each one into google maps would not work).

You can do reverse geocoding with Google Maps API using the following HTTP request:

Simple CSV:

http://maps.google.com/maps/geo?q=40.756041,-73.986939&output=csv&sensor=false

More Complex XML:

http://maps.google.com/maps/geo?q=40.756041,-73.986939&output=xml&sensor=false

Simply change the "q" parameter with your latitude,longitude.

Note that the Google Maps API has a limit of 15,000 request per IP address per day. (Google Maps API FAQ)

What about doing reverse geocoding with the Google Maps API?

Here is a bulk Reverse Geocoder which, internally, uses the Google Maps API to reverse geocode an entire series (in a CSV file) of latitude and longitude pairs.

It would make this fairly easy.
