Can I find out if a coordinate is inside a city?

Question

Let\'s say I have a LatLng object, is there any way of checking if it represents a possible location within a city? How can I get the limits of a city? I\'m using Google Map

Answer 1

You can use Reverse Geocoding in the Google Geocoder API and check the locality entries and perhaps sublocality entries of results returned. http://code.google.com/apis/maps/documentation/geocoding/#Types

Note that this probably won't work so well if you have addresses all over the world and want to know "What city is this LatLng in?" On the other hand, it will probably work reasonably well if you want to know "Is this LatLng within Chicago?" There are areas of the world where the data is fairly complete and sensible, and areas where it is incomplete and/or organized in ways you might not expect. (Apparently, the UK uses "county" and "state" very differently from the USA, for example. Even if I'm wrong about that, you get the idea.)
