  2. GIS in geospatial intelligence - Wikipedia

    en.wikipedia.org/wiki/GIS_in_geospatial_intelligence

    Geographic information systems (GIS) play a constantly evolving role in geospatial intelligence (GEOINT) and United States national security.These technologies allow a user to efficiently manage, analyze, and produce geospatial data, to combine GEOINT with other forms of intelligence collection, and to perform highly developed analysis and visual production of geospatial data.

  3. National Geospatial-Intelligence Agency - Wikipedia

    en.wikipedia.org/wiki/National_Geospatial...

    NGA is a member of the National System for Geospatial Intelligence (NSG) and the larger Allied System for Geospatial Intelligence (ASG), which includes close allies Canada, the United Kingdom, Australia, and New Zealand. [29] The U.S. and those four nations also form the Five Eyes intelligence alliance. [51]

  4. Geospatial intelligence - Wikipedia

    en.wikipedia.org/wiki/Geospatial_intelligence

    A de facto definition of geospatial intelligence, which is more reflective of the broad international nature of the discipline, is vastly different from the de jure definition expressed in U.S. Code. This de facto definition is: Geospatial Intelligence is a field of knowledge, a process, and a profession.

  5. Geospatial Intelligence Battalion - Wikipedia

    en.wikipedia.org/wiki/Geospatial_Intelligence...

    The United States Army Geospatial Intelligence Battalion (GEOINT Battalion or AGB), previously known as the 3rd Military Intelligence Center, is a military intelligence battalion specializing in the production and exploitation of geospatial intelligence (GEOINT), and the only operational military command at the National Geospatial-Intelligence Agency (NGA). [1]

  6. Location intelligence - Wikipedia

    en.wikipedia.org/wiki/Location_intelligence

    The term "location intelligence" is often used to describe the people, data and technology employed to geographically "map" information. These mapping applications like Polaris Intelligence can transform large amounts of data linked to location (e.g. POIs, demographics, geofences) into color-coded visual representations (heat maps and thematic maps of variables of interest) that make it easy ...

  7. GIS file format - Wikipedia

    en.wikipedia.org/wiki/GIS_file_format

    A GIS file format is a standard for encoding geographical information into a computer file, as a specialized type of file format for use in geographic information systems (GIS) and other geospatial applications.

  8. Data model (GIS) - Wikipedia

    en.wikipedia.org/wiki/Data_model_(GIS)

    Because the world is much more complex than can be represented in a computer, all geospatial data are incomplete approximations of the world. [9] Thus, most geospatial data models encode some form of strategy for collecting a finite sample of an often infinite domain, and a structure to organize the sample in such a way as to enable interpolation of the nature of the unsampled portion.

  9. Earth Gravitational Model - Wikipedia

    en.wikipedia.org/wiki/Earth_Gravitational_Model

    The NGA provides the models in two formats: as the series of numerical coefficients to the spherical harmonics which define the model, or a dataset giving the geoid height at each coordinate at a given resolution.
