It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space.
Here Geospatial Intelligence, or the frequently used term GEOINT, is an intelligence discipline comprising the exploitation and analysis of geospatial data and information to describe, assess, and visually depict physical features (both natural and constructed) and geographically reference activities on the Earth.
Geoinformatics is a scientific field primarily within the domains of Computer Science and technical geography. [1] [2] It focuses on the programming of applications, spatial data structures, and the analysis of objects and space-time phenomena related to the surface and underneath of Earth and other celestial bodies.
