. . "Earth3D was developed as part of a diploma thesis of Dominique Andre Gunia at Braunschweig University of Technology to display a virtual globe of the earth. It was developed before Google bought Keyhole, Inc and changed their product into Google Earth. Earth3D downloads its data (satellite imagery and height data) from a server while the user navigates around. The data itself is saved in a Quadtree."@en . . . . . . . . "1.0.5" . "Earth3D"@en .
