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. Users can explore the globe by entering ...
NASA WorldWind, an open-source virtual globe with stars and advanced atmosphere & sunlight effects. A virtual globe is a three-dimensional (3D) software model or representation of Earth or another world. A virtual globe provides the user with the ability to freely move around in the virtual environment by changing the viewing angle and position.
World map. A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
Raised-relief map. A raised-relief map, terrain model or embossed map is a three-dimensional representation, usually of terrain, materialized as a physical artifact. When representing terrain, the vertical dimension is usually exaggerated by a factor between five and ten; this facilitates the visual recognition of terrain features.
Website. www.earth3d.org. Earth3D was developed as part of a diploma thesis of Dominique Andre Gunia at Braunschweig University of Technology [1] 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 ...
Equirectangular projection of the world; the standard parallel is the equator (plate carrée projection). Equirectangular projection with Tissot's indicatrix of deformation and with the standard parallels lying on the equator True-colour satellite image of Earth in equirectangular projection Height map of planet Earth at 2km per pixel, including oceanic bathymetry information, normalized as 8 ...
As an atlas software, the 3D World Atlas has many features. These include, but are not limited to, world maps on a 3D globe, thousands of tables and charts, national flags, and a world clock. [2] The software also includes distance measuring and in-depth information on every country, including independence days, government types, and such. [2]
Earth Gravitational Model. The Earth Gravitational Models (EGM) are a series of geopotential models of the Earth published by the National Geospatial-Intelligence Agency (NGA). They are used as the geoid reference in the World Geodetic System. The NGA provides the models in two formats: as the series of numerical coefficients to the spherical ...
