Introduction
Geospatial technologies are ultimately dependent upon the georeferencing grid systems used to assign coordinates to locations on or near the surface of the Earth. Cartography and geodesy have devised a multitude of such grid systems over time for various purposes, including the Universal Transverse Mercator (UTM) system, the U.S. Military Grid Reference System (MGRS), the State Plane Coordinate System (SPCS), the British National Grid (BNG), and many others. Regardless of their exact technical specifications, all such grid systems share: 1) a structured terminology and explicit syntax for coordinate references; 2) a specific mechanism for producing ...
