10 Amazing Google Earth Add-Ons

Not content with photographing, filming, or otherwise recording every nook and cranny of our planet, some people choose to spend their spare time creating virtual 3D models of real-life buildings to further enhance the immersive nature of Google Earth. Google encourages local governments and colleges to produce 3D models of their cities, towns, and campuses--and for those of us who don't have the resources available to institutions, it provides SketchUp, software with which anyone can fairly easily create a 3D model of a house, school, office, shed, or treehouse. The Google Earth 3D Warehouse displays the models, and your models may be selected to become part of the 3D Warehouse layer within Google Earth.
