GIS, Definition
• GIS is a system of hardware and software used for storage,
retrieval, mapping, and analysis of geographic data, which is
geographically referenced to a map projection in an earth coordinate
system.
• GIS is a special-purpose digital database in which a common spatial
coordinate system is the primary means of reference.
• GIS is a facility for preparing, presenting, and interpreting facts that
pertain to the surface of the earth.
• GIS is an information system that is designed to work with data
referenced by spatial or geographic coordinates.
• GIS is "an organized collection of computer hardware, software,
geographic data, and personnel designed to efficiently capture,
store, update, manipulate, analyze, and display all forms of
geographically referenced information."
• A GIS is a database mixed with a map.
