  1. 2 GIS COMPONENTS

  2. Basic COMPONENTS • Hardware • Software • Data • Institution

  3. GIS COMPONENTS (I) • hardware • computers to run software • software • computer program to process data • custom-written software • generic programs are more popular • data • processed for information retrieval • most costly compared with hardware and software • longer life span

  4. Institution • individual and/or organisation that use or implements GIS • critical component as it decides the success of implementation • need for GIS professional to analyze, research, design complex GIS applications • difficult to change humans to adapt with new technology • easily overlooked

  5. GIS SUB-SYSTEMS / FUNCTIONS(I) • data acquisition/input • define, entry and preliminary processing data • Involves digitizer, scanner, survey equipment, etc. • data management • control existence, update, recall and deletion of data • database management system

  6. GIS SUB-SYSTEMS / FUNCTIONS (II) • analysis of data • generation of information from data archives • spatial analysis software • value of GIS depends on the analytic functions it provides • information output • generated information conveyed to the users • information managed by computers can be plotted, printed or exported into other systems.

  7. Other views on GIS Components and functions • Four major components of GIS (Martin, 1991): • collection, input and correction • storage and retrieval • manipulation and analysis • output and reporting • These components dictate the functions that a GIS can carry out.

  8. …GIS Components and functions • GIS capabilities can also be highlighted according to functions(Martin,1991; Anselin,1998).
