Reverse GeoCoding

Google map has APIs to do reverse geocoding which is a process to get latitude and longitude by location address.

There is alternative service to get reverse geocoding call GeoNames. I will show you how to use both of them using geopy A Geocoding Toolbox for Python

Install geopy

svn checkout http://geopy.googlecode.com/svn/branches/reverse-geocode geopy

cd geopy/

sudo python setup.py install

Using Google API

from geopy import geocoders
g = geocoders.Google(GOOGLE_KEY)
(place, point) = g.geocode("562 Kendall Ave, Palo Alto, CA")
(new_place,new_point) = g.reverse(point)

Using GeoNames

from geopy import geocoders
g = geocoders.GeoNames()
(place, point) = g.geocode("Palo Alto, CA 94306")
(new_place,new_point) = g.reverse(point)
