Creating KML Regions from ArcGIS Data Using Arc2Earth

Posted on January 30, 2008. Filed under: Google Earth, Regions |

Our previous posts on basic and advanced KML Region concepts gave you some background on how this functionality can be used allow you to stream your data in pieces instead of as a whole making it possible to deliver large datasets to the Google Earth viewer.  In this post you will discover how to use Arc2Earth with your existing ArcGIS data to create these powerful features.

 Arc2Earth can be used to create Google Earth Regions through the Regions tab with the Publisher version of Arc2Earth.  The General Options button displays the Region Options dialog which can be used to set the fade effects and level of detail (LOD) for the region.  You must also select a region level which is basically a course grain level similar to the levels of map tiles used in Google Maps or MS Virtual Earth.  Each level represents an approximate map scale.  The Visualize button displays a map window with the grid showing the regions for your export along with your layer data. 

The Visualize window is particularly helpful in allowing you to see the extent of the Regions that will be created along with your data.  The red lines displayed in the viewer indicate how your data will be regionalized.  You can also dynamically reset the region level through this window to see the effect this will have on the size of the Regions.  Map navigations tools are also provided.
