distinguishes GIS from other information systems.
Geographically Referenced Data
• 1. Spatial Data • 2. Attribute Data • 3. Joining Spatial and Attribute Data
2. Software
The heart of the system for the implementation of the various operations of GIS functions, including data input, processing, database management, spatial analysis and graphical user interface (GUI).
