Chapter Outline
– Points 1 What Is GIS? – Points 2 Components of GIS – Points 3 GIS Function components – Points 4 A Brief History of GIS – Points 5 Relationship of GIS to other
Geographically Referenced Also called geDospaattaial data
Describe both locations and characteristics of spatial features
Note: Ability to process geographically referenced data distinguishes GIS from other information systems.
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).
2. Software: Computer System to Support data collection, storage, processing, and answer the users’ question.
3.Spatial Data: The object of analysis and processing, Constitute a basis for the application.
