Taken from the Drupal Project Page:

The GMap module is primarily an API packaged with a few modules to give some functionality.

The API allows developers of other modules to include Google Maps in their module. There is also a macro generator and a filter to insert a google map from a macro into any node where the filter is run.

A second module packaged with gmap.module integrates with the location.module and allows users that have lat,long information entered for the user to be displayed on a single map so that you can see where in the world all of your users are coming from. The gmap.module also includes functionality to allow users to set their latitude and longitude on a gmap in an interactive fashion.

This module also adds some functionality to location.module that can allow the node locations to be set in an interactively. Then the location of the current node can be shown in a block if it has lat/long information stored for it in the location.module. All of the nodes that have lat/long location information can be viewed on a common map.
