The folks at BrightGIS have created a geo-biography of Sen. John McCain’s early life and military service which you can view in Google Earth. You simply download their McCain KML file , and follow the instructions you’ll see inside GE. I like they way they have used placemarks to view the content and navigate between the different locations of McCain’s life. There are other techniques for navigating content, but this one works pretty well I think. The file is designed as a political promotion, but is informative and useful and the links for “getting involved” and contributing are not too obtrusive. BrightGIS offers services to build Google Earth/Maps content. You can also view their McCain file in Google Maps, but the GE version is more entertaining.
