MapIt is a service that maps geographical points to administrative areas. This edition is based on source data from the totally amazing OpenStreetMap project, so add your boundaries there if they’re missing. If you’re in the UK our MapIt UK with open Ordnance Survey data will probably be more useful.

MapIt is useful for anyone who has the co-ordinates of a point on Earth, and who needs to find out what country, region, city, constituency, or state it lies within. It’s also great for looking up the shapes of all those boundaries.

Charitable, low volume use of this service is free – read more.
You can download the source on Github.
