Summary
Geospatial information is data referenced to a place—a set of geographic coordinates—which can often be gathered, manipulated, and displayed in real time. A Geographic Information System (GIS) is a computer system capable of capturing, storing, analyzing, and displaying geographically referenced information. In recent years consumer demand has skyrocketed for geospatial information and for tools like GIS to manipulate and display geospatial information. Global Positioning System (GPS) data and their integration with digital maps has led to the popular handheld or dashboard navigation devices used daily by millions. The federal government and policy makers increasingly use geospatial information and tools like GIS for
producing floodplain maps, conducting the Census, mapping foreclosures, and responding to natural hazards such as wildfires and hurricanes. For policy makers, this type of analysis can greatly assist in clarifying complex problems that may involve local, state, and federal government, and affect businesses, residential areas, and federal installations.
