• MapsOfIndia.com
  A wide variety of static and interactive maps, datasets, and general location-oriented information about India. Substantial advertising matter, and some of the functionality depends upon the user registering at the site. Some of the maps are very nicely organized, though quite a few (e.g. the language maps) are quite superficial and not terribly informative.
