MapIt is an open source project to help people run a web service that maps geographical points to administrative areas. It 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.
It was created in 2003 by mySociety, a UK charity, for use by their various tools needing admin area lookup.
MapIt can be installed as a Django app, or as a standalone server. For full details, please see our site at http://code.mapit.mysociety.org/ for help and documentation.
