Google Earth
  • Provides free access to a rich resource of satellite imagery and geographic data
  • Excellent for visualization
  • On-screen digitizing capabilities allow mapping of features
    • Features can be saved as kml files
    • kml files cannot be directly loaded into a GIS
the convert kml to shp tool
The “Convert KML to SHP” tool
  • Converts kml features to shapefile features
    • Names and descriptions of kml features are retained in the shapefile
  • Easy to use - run as a tool in ArcToolbox
  • Runs on ArcView 9.2 – no extensions required.
  • Works with kml files created by Google 4.2
    • May not work with older versions

Using Google Earth Imagery in a GIS
  • Google Earth imagery cannot be downloaded.
  • Screen captures can be georeferenced and used in a GIS.
  • Reference points are needed to geo-reference a screen capture.
  • Features digitized in Google Earth can be used as references.
