All KH-11 Keyhole satellites on orbit, orbital constellation status of September 2013. Nine KH-11 satellites were launched between 1976 and 1990 aboard Titan-3D and Titan-34D launch vehicles, with one launch failure. For the following five satellite launches between 1992 and 2005, a Titan IV launch vehicle was used.
Google Earth. Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering ...

Keyhole Markup Language ( KML) is an XML notation for expressing geographic annotation and visualization within two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer. It was created by Keyhole, Inc, which was acquired by Google in 2004.
Terravision (computer program) Terravision is a 3D mapping software developed in 1993 by the German company ART+COM in Berlin as a "networked virtual representation of the Earth based on satellite images, aerial shots, altitude data and architectural data". [1] Development of the project was supported by the Deutsche Post (now Deutsche Telekom ).
