Google Earth Blog has recently described two new freeware applications for Google Earth that extend the functionality of the free program well beyond the Plus version. Now that I’ve downloaded GE Graph, I am delighted to report that it works really well. Simply create a folder of placemarks in Google Earth, then save the folder as .kml. The folder opens in GE Graph; just add the data for the placemarks, configure your choice of graph and see the results in Google Earth. The thumbnail below illustrates my first effort at plotting river velocities downstream.
