Go to: Google Earth description. Google Earth website. Developer: Google Inc. Google Earth is a virtual globe, map and geographical information program that was originally called EarthViewer 3D, and was created by Keyhole, Inc. Google Earth maps the Earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe.
It puts a planet's worth of imagery and other geographic information right on your desktop. View exotic locales like Maui and Paris as well as points of interest such as local restaurants, hospitals, schools, and more. Google Earth icon size: px x px. Note: You can click on any file extension link from the list below, to view its detailed information. New touring feature that allows a tour or presentation to be recorded and played back.

They typically are architected to support data layers for various data formats. Most Virtual Globes act as clients to a map server which delivers the map imagery, vector and elevation data. The map servers typically deliver data via HTTP get requests based on the coordinates of the area being zoomed in on and at a resolution and scale based on the user's reference point and view.
Map imagery data for the planet earth is typically too large to be included with the globe application. Some map servers like Microsoft's Bing map server, support even higher imagery resolution from aircraft and is of an unknown but gigantic data footprint size.
Maps vs Virtual Globes: Virtual Globes are 3-D with a true spherical projection mimicking reality with little or no distortion, true distances and continuous. Maps are 2-D and the projection of a 3-D Earth. Various projections are used, each with their own flaws:.
