Google Earth is a web and 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.
To acquire topographic data, the SRTM payload was outfitted with two radar antennas. [2] One antenna was located in the Shuttle's payload bay, the other – a critical change from the SIR-C/X-SAR, allowing single-pass interferometry – on the end of a 60-meter (200-foot) mast that extended from the payload bay once the Shuttle was in space.

The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
With a topographic prominence of 20,194 feet (6,155 m) [3] and a topographic isolation (the distance to the nearest peak of equal or greater height) of 4,621.1 miles (7,436.9 km), [3] Denali is the third most prominent and third-most isolated peak on Earth, after Mount Everest and Aconcagua.
A topographic map of Stowe, Vermont with contour lines This false-color satellite image illustrates topography of the urban core of the New York metropolitan area, with Manhattan at its center. Topography is the study of the forms and features of land surfaces .
3D rendering of a DTM of Tithonium Chasma on Mars. A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid.
Topographic maps are also commonly called contour maps or topo maps. In the United States, where the primary national series is organized by a strict 7.5-minute grid, they are often called or quads or quadrangles. Topographic maps conventionally show topography, or land contours, by means of contour lines.
