"Google Earth for ArcGIS Users "
In this course students learn how to integrate existing ESRI format data including shapefiles and geodatabases into a Google Earth format for display and manipulation. Students will master the use of various ArcGIS tools for directly converting both vector and raster data into Google Earth KML files. In addition, we will cover a number of other important topics including the ability to add a fourth dimension to your data (time), use Google Earth in an offline mode without the use of an Internet connection, create KML files through the use of a text editor, and integrate your existing imagery data into the display.  Finally, we'll also explore the various navigational, display, and search tools for optimizing your visualization experience with Google Earth.

"Arc2Earth for ArcGIS Users "
As an ArcGIS extension, Arc2Earth was initially built as a highly efficient tool for exporting ArcGIS data including the geometric representations of the data, labels, renderers, graphics, and layouts into a format that Google Earth understands.  However, as you’ll see, Arc2Earth has evolved into more than just an ArcGIS data export tool for Google Earth.  In addition to all the great export functionality you can also import KML/KMZ files directly to ArcGIS in geodatabase format, view raster tiles (aerial and hybrid imagery) provided by Microsoft, Yahoo, and Ask.com from within ArcMap, export your data as map tiles to Google Maps and Virtual Earth, publish data to web enabled viewers, automate exports through the scheduler process, and much more.
