[5] Google is the most common recipient of geo-fence warrants and the main provider of such data, [ 4 ] [ 6 ] although companies including Apple , Snapchat , Lyft , and Uber have also received such warrants.
The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.
A location-based firearm is a gun that uses electronic technologies such as geofencing to restrict its firing to authorized locations, thereby allowing its use for protecting life and property in those locations while preventing its use in other locations for crimes such as robberies, drive-by shootings, assassinations, and massacres.
Georeferencing or georegistration is a type of coordinate transformation that binds a digital raster image or vector database that represents a geographic space (usually a scanned map or aerial photograph) to a spatial reference system, thus locating the digital data in the real world.
Geographic data and information is defined in the ISO/TC 211 series of standards as data and information having an implicit or explicit association with a location relative to Earth (a geographic location or geographic position).
