What is GIS?
Geography is a science that deals with the earth's surface and the objects found on it. Geographic Information Systems use technology to help manage, analyze and share geographic knowledge.
Geographic Information Systems use detailed computer files that allow users to visualize information as multiple layers of data overlaid on a map. For example, a GIS file might begin with a background layer that shows detailed aerial photographs of the region. Subsequent layers could include street maps, utility lines, population and demographic data, land uses, the location of fire and police stations, transit routes or any other information with a geographic component.
Local governments increasingly use GIS to plan future development, track road maintenance and other public works projects, and plan emergency response. Working through MARC, local GIS managers formed the KC Metro GIS committee to develop policies and technical standards for sharing GIS information at the regional level.
Sharing GIS files will allow, for the first time, the creation of a regional map that can seamlessly zoom all the way from the broad, eight-county “big picture” down to individual parcels, the smallest units of land ownership. MARC and KC Metro GIS are working with local governments to develop a system for sharing GIS files to maximize their usefulness to public decision-making.
