This blog posting is dedicated to lesser known layers. One of the challenges of our work here is to make Google Earth users aware of the compelling content we have available in these layers. So here is my contribution to that effort:
Appalachian Mountain Top Removal - Under Global Awareness. This layer brings public attention to the devastating environmental effects of mountain top removal in the eastern United States.
Volcanoes - Under Geographic Features. View information from the Smithsonian Institute about volcanic formations around the world.
Alternative Place Names - Open this folder and check the appropriate language to view names (and spellings) of places around the globe. You can use this layer in conjunction with the Populated Places layer to see interesting contrasts of how place names are spelled (example "Al Qahirah" versus "Cairo".
European Space Agency - Under Featured Content. Check this to view stunning alternate satellite imagery of places around the world, such as active volcanoes, flooding, mountain ranges and more.
