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. KML became an international standard of the Open Geospatial ...
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 ...
The first series of CORONA satellites were the Keyhole 1 (KH-1) satellites based on the Agena-A upper stage, which offered housing and an engine that provided attitude control in orbit. The KH-1 payload included the C (for CORONA) single panoramic camera built by Fairchild Camera and Instrument with a f/5.0 aperture and 61 cm (24 in) focal length.
Keyhole's main application suite, Earth Viewer, and Keyhole Markup Language (KML), formed the basis for Google Earth. Under McClendon's tenure, Google Geo products included Google Maps, Google Maps API, Street View, Google Local Search, Panoramio, Sketchup, Waze, Google Earth, and Google Earth Engine.
KML, made popular by Google, complements GML. Whereas GML is a language to encode geographic content for any application, by describing a spectrum of application objects and their properties (e.g. bridges, roads, buoys, vehicles etc.), KML is a language for the visualization of geographic information tailored for Google Earth.
The WorldWind Java version was awarded NASA Software of the Year in November 2009. [3] The program overlays NASA and USGS satellite imagery, aerial photography, topographic maps, Keyhole Markup Language (KML) and Collada files.
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 ).
Wikipedia uses a variety of multimedia files to enhance content and explain concepts that are difficult to convey via text alone. Keyhole Markup Language (KML) files specify a set of features that can be displayed in compatible mapping or geospatial software, including web mapping services. On Wikipedia, KML files commonly accompany articles related to linear features such as roads, train ...
