About geographic information systems (GIS):

Definition: Computer program and associated databases that store, integrate, analyze, and process geospatial data. Data is usually organized in layers containing distinct classes of geographic entities, such as hydrologic, cultural, and topographic features. [Adapted from Glossary of Geology, 4th ed.]

Scope note: Use this term only for information that is about GIS and not for the use of GIS in applications and projects.
