1 HARDWARE COMPONENTS OF A GIS

 

The general hardware components of a GIS are shown in the figure

 

CPU -Central processing unit is linked to disk drive, which provides space for storing data and programs.

 

Digitizer -It is a device used to convert data from maps and documents into digital form (Raster to Vector).

 

Plotter -Plotter is used to present the results of the data processing on a paper.

 

Tape drive -It is used to store data or programs on magnetic tape for communicating with other systems.

 

VDU (Visual Display Unit)-It is used to control the computer and the otherperipherals. It is otherwise known as terminal or workstation.
