Geolocation provides a Drupal 7 field for storing Longitude/Latitude pairs.
It is a light-weight alternative for the Geofield module, since it does not automatically enables own widgets, but implements the widgets in submodules.
Users of Address field can use Geolocation field to geocode their address using the Geocoder helper module.
Other helper modules:
- Geolocation Views provides a Google Maps Views plugin
- Geolocation Proximity adds Views handlers for proximity searching
