Geographic data is an important aspect of any location system. Geographic Information Systems (GIS) provide the tools to provision and administer base map data such as manmade structures and terrains. GIS is also used to manage point-of-interest data such as location of gas stations, restaurants, nightclubs etc. Finally GIS information also includes information about the radio frequency characteristics of the mobile network. This allows the system to determine the serving cell site of the user.
