Expanded Features - Geographic information systems

According to the U.S. Census Bureau, a geographic information system (GIS) is "a computer system for the input, storage, processing, applications development, retrieval, and maintenance of information about the points, lines, and areas that represent the streets and roads, rivers, railroads, geographic entities, and other features on the surface of the Earth—information that previously was available only on paper maps." As an education LDS tool, a GIS offers unique functionalities such as providing landscape views of student population characteristics and growth, achievement data, and graduation rates. Policymakers, researchers, and parents are often especially interested in this type of information.
