Geomapping with Reilly

 refers to an unmarked and repeatable quest in Fallout 3.

After completeing the quest Reilly's Rangers and offering Reilly your help with their mapping service, she will give you a Geomapper Module. As long as you have the module in your inventory, it will record every new location you discover, for which Reilly will pay you 30 caps per location every time you return to the Ranger Compound and talk to her. Don't forget to speak to her right away, after receiving the Module. She will pay you for the locations which you already have on your map.

Bugs

 * After getting the mapping module from Reilly, sometimes all your notes up to date will disappear.
 * Another possible bug is that you won't get paid for locations you already have the first time you talk to her after she gives you the module. She will say they already know about all of those locations and will give you nothing. If this happens, try immediately talking to her again. If Reilly still won't pay you for the locations you have already discovered, try leaving the Ranger's compound and re-entering before talking to her again.
