GIS Software Categories

Often it is distinguished between the following types of GIS software:

  • Desktop GIS are used to create, edit, manage, analyse and display geographic data. They are sometimes classified into three functionality categories: GIS Editor, GIS Analyst and GIS Viewer.
  • Spatial database management systems (Spatial DBMS) are used to store the data, but often also provide analysis and data manipulation functionality.
  • WebMap Servers are used to distribute maps over the Internet (see also for the Open Geospatial Consortium standards: WFS and WMS).
  • Server GIS provide basically the same functionality as desktop GIS but allow to access this functionality via networks (so-called geoprocessing).
  • WebGIS Clients are used for data display and to access analysis and query functionality from Server GIS over the internet or intranet. Usually One distinguishes between Thin and Thick client. Thin clients (e.g. a web browser used to display google maps) provide only display and query functionality while Thick clients (e.g. Google Earth or a Desktop GIS) provide often additional tools for data editing, analysis and display.
  • Libraries and Extensions provide additional functionality that is not part of the basic GIS software because it may be not needed by the average user. Such additional functions can cover tools for terrain analysis (e.g. SEXTANTE), tools to read specific data formats (e.g. GDAL and OGR), or tools for the cartographic display of geographic data (e.g. PROJ4).
  • Mobile GIS are used for data collection in the field.

Famous quotes containing the word categories:

    All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.
    Georg Wilhelm Friedrich Hegel (1770–1831)
