Currently, new mapping being conducted takes full advantage of state of the art geographic information system (GIS) technology. A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. It allows the end-user to view a map with as much or as little detail as needed. From the GPS in your car to MapQuest to the Census Bureau Tigerline maps, GIS is the basis for all of these products. Even many historical maps are being scanned and converted to formats that can be manipulated by GIS systems.
