Reverse Geocode

The module provides reverse geocoding capabilities to Location CCK fields, which means that you can fill all the fields of a location field through a click on a button. It relies on Google Geocoding API.

Comparing to other modules that perform this task, this one stands out for out-of-the-box integration with Location module, as well as for being very lightweight.

To use the module, you need:
A valid google maps api (of course)
'Use a Google Map to set latitude and longitude' checked at /admin/settings/location
'Coordinate Chooser' set to 'Allow' or 'Require' in your Location CCK field's Locative information -> Collection settings

Once you're done with the above:

Just pick a location on the map, click the "Fetch Address" button and it will fill in the available fields for the location you've picked.

PS:
For now, the module stands just as proof-of-concept, in response to a thread open since November 8 2007, which can be seen here.
