1. The AJAX API Property
The AJAX API Property retrieves an approximate location from a user's IP address. Google Blogoscoped has released an example Google Map that uses the AJAX API property to centre the map on the user's location and provide the results of an image search based on the user's location. The map is called Where are You?
2. The Gears Geolocation API
The Gears Geolocation API provides a way to get a more precise estimate of a user's location. On mobile devices with Gears installed, the Geolocation API can triangulate a location on nearby cell-phone masts to get a more accurate position fix.

At the beginning, Google Geolocation API has determined the location for only Americans, for the other it has returned "unknown". Later this service was advanced, but it often does not show results even for developed countries as yet. For such cases, there is a simple javascript extension to the Google API, which gives back the country of user.
