GIS: GEOGRAPHIC INFORMATION SYSTEM • Geographic information made digital and aligned to a common reference system (georeferenced) • GIS layers are by national, state and local sources • Can provide information on a many types of features, both natural resource and societal • Combines geographic layers with descriptive data about those layers UNH Cooperative Extension 2010
What is GIS? GIS = Geographic Information System A system for • capturing • managing • manipulating • displaying • analyzing spatial data UNH Cooperative Extension 2010
