GIS leverages new technologies to dynamically create maps providing value added service. In addition to creating maps, GIS allows for descriptive information (known as attributes) to be stored in a database that is linked to its associated map feature. For example, information such as the owner of a property, the length of a road, or the name of a park are recorded.

Queries such as, "List the addresses and show the properties that are located within the 20-year flood plain" are now within the realm of GIS.
