  2. Military Grid Reference System - Wikipedia

    en.wikipedia.org/wiki/Military_Grid_Reference_System

    The Military Grid Reference System (MGRS) [1] is the geocoordinate standard used by NATO militaries for locating points on Earth. The MGRS is derived from the Universal Transverse Mercator (UTM) grid system and the Universal Polar Stereographic (UPS) grid system, but uses a different labeling convention.

  3. The World Geographic Reference System (GEOREF) is a geocode, a grid-based method of specifying locations on the surface of the Earth. GEOREF is essentially based on the geographic system of latitude and longitude , but using a simpler and more flexible notation .

    The Ordnance Survey National Grid (United Kingdom) and other national grid systems use similar approaches. In Ordnance Survey maps, each Easting and Northing grid line is given a two-digit code, based on the British national grid reference system with an origin point just off the southwest coast of the United Kingdom. The area is divided into ...

    The United States National Grid (USNG) is a multi-purpose location system of grid references used in the United States. It provides a nationally consistent "language of location", optimized for local applications, in a compact, user friendly format. It is similar in design to the national grid reference systems used in other

  7. Kill box - Wikipedia

    en.wikipedia.org/wiki/Kill_box

    A type of fire support coordinating measure (FSCM), a kill box is often defined by a grid reference system based on lines of latitude and longitude, superimposed upon a map of an area of operation. Each square of the grid may be sub-divided into smaller boxes, each of which may carry its own level of permission or restriction on the use of air ...

  8. Spatial reference system - Wikipedia

    en.wikipedia.org/wiki/Spatial_reference_system

    A spatial reference system (SRS) or coordinate reference system (CRS) is a framework used to precisely measure locations on the surface of Earth as coordinates. It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space.

  9. Ordnance Survey National Grid - Wikipedia

    en.wikipedia.org/wiki/Ordnance_Survey_National_Grid

    The Ordnance Survey National Grid reference system (OSGB), also known as British National Grid (BNG), [1] [2] is a system of geographic grid references, distinct from latitude and longitude, whereby any location in Great Britain can be described in terms of its distance from the origin (0, 0), which lies to the west of the Isles of Scilly.
