GIS Data Viewers

If you do not already have a GIS software package, there are a number of Desktop GIS Data Viewers that you can use to visualize the data in this site.  Thanks to John Hickok for putting this together.

These are generally in descending order of usage and ease, with the top 2 (QGIS and ArcExplorer are the most native).

Desktop Viewers

  1. ESRI ArcGIS Desktop (“ArcMap”) – http://www.esri.com/software/arcgis/arcgis-for-desktop
    1. This professional level GIS software is used by the County to build and maintain the data on its site.  While not free, ArcGIS Desktop is the most powerful and widely used GIS software in the world.
  2. QGIS (Formerly “Quantum GIS”) – http://qgis.org/en/site/
    • From its humble beginnings in 2002 as a GIS viewer for Linux, this software is said to have the strongest community support and growth. With a great deal of grass-roots popularity, QGIS is regarded by many as having the greatest combination of powerful functionality and ease of use.
  3. ArcGIS Explorer Desktop – http://www.esri.com/software/arcgis/explorer
    • Esri’s free viewer for the desktop, capable of viewing ArcGIS Online layers in addition to local data.  Does not provide comprehensive GIS tools.
  4. OpenJUMP (Open Java Unified Mapping Platform) – http://www.openjump.org/
    • This open source project is popular amongst JAVA programmers. Its greatest strengths amongst open source GIS enthusiasts are its ease of use and well developed drawing tools.
  5. uDig (User-friendly Desktop Internet GIS) – http://udig.refractions.net/
    • The community that surrounds this software enjoy uDig’s compatibility with open source powered GIS web servers. “If it renders on uDIG, it’ll render on Open Layers”.
  6. gvSIG (Generalitat Valenciana, Sistema d’Informació Geogràfica) – http://www.gvsig.org/web
    • With help from the European Union, the software was developed under a contract from the Spanish government.
  7. Bentley View V8i – http://www.bentley.com/en-US/Products/Bentley+View/
    • This free viewer can be used for DGN and DWG CAD files.
