  1. GIS Software

  2. GIS Software • The evolution of GIS software • Architecture of GIS software • GIS software components • GIS software functions • Types of GIS software • Usage of GIS software GIS Software

  3. The evolution of GIS software • Early days: a collection of computer programs • 1970s – 80s: ‘standard’ user interface based on command lines • Late 1980s: GUI and customisation capability • 1990s: Software modules and customisation • Today: Web service GIS Software

  4. Command-line user interface Arcplot: aselect roads arcArcplot: aselect roads nodeArcplot: reselect roads node town = 'ARMIDALE' ~Arcplot: or town = 'FORSTER' ~Arcplot: or town = 'TAMWORTH' or town = 'COFFS HARBOUR' ~Arcplot: or town = 'MURWILLUMBAH' or town = 'TENTERFIELD' ~Arcplot: or town = 'NEWCASTLE'Arcplot: arcs roadsArcplot: nodes roadsArcplot: nodetext roads townArcplot: aselect roads nodeArcplot: netcover roads orderedArcplot: impedance ft-trvltime tf-trvltimeArcplot: path *Arcplot: routeline roads ordered 6 GIS Software

  5. Graphical user interface GIS Software

  6. Software modules GIS Software

  7. Web Service GIS Software

  8. Architecture of GIS software • Project, departmental and enterprise GIS • Project: single database established for the project primarily used by one user • Department: centralised database used by multiple users • Enterprise: distributed database shared by large number of users on the network GIS Software

  9. The three-tier architecture User Interface Tools Data Management Data GIS Software

  10. Client/server architecture “Fat User” “Thin User” Desktop Browser Desktop Network Application Server Data Server Data Server Data Data GIS Software

  11. Project, departmental and enterprise GIS Project Department Enterprise GIS Software

  12. GIS software components • User applications • Tools • Data access GIS Software

  14. Basic GIS functions • Input and verification • Storage and management • Processing and analysis • Output and visualisation GIS Software

  15. Input & Verification Storage & management Query Output & visualisation Processing & analysis GIS GIS software functions (cont.) GIS Software

  16. Input • Data capture • Editing and error correction • Geocoding GIS Software

  17. Storage and management • Data conversion and access • Data integration • Database management • Data retrieval and query • Data updating • Metadata management GIS Software

  18. Processing and analysis • Reclassification • Transformation • Map overlay • Spatial analysis • Modelling • Simulation GIS Software

  19. Output and visualisation • Interactive graphical display (softcopy) • Cartographic output and production (hardcopy) • Data exchange output • Publication and on-line service GIS Software

  20. Types of GIS software • Desktop GIS • Server GIS • Developer GIS • Hand-held • Others (e.g. CAD-based GIS) • Internet GIS GIS Software

  27. Usage of GIS software InternetServerDesktopDeveloper Number ofUsers Cost Functionality GIS Software

  28. Usage of GIS software The estimated regular GIS users (sites) in 2005. If Internet GIS users were included, the total usage of GIS software rose to about 10 million, excluding users of GIS products such as maps, charts and reports. Data source: Longley et al., 2005 GIS Software

  29. Summary • GIS software is a fundamental and critical part of any operational GIS. • Today there are many types of GIS software product to choose from. • There are also a number of ways to configure implementations. • The development of GIS software has now a very rapid rate. GIS Software
