It’s also referred as 10-digit coordinates. An example of an MGRS coordinate, or grid reference, would be 4QFJ12345678, which consists of three parts: 4Q (grid zone designator, GZD) FJ (the 100,000-meter square identifier) 1234 5678 (numerical location; easting is 1234 and northing is 5678, in this case specifying a location with 10 m resolution)
For example, in the Military Grid Reference System, the above coordinate is in grid 11U (representing UTM Zone 11 5xxxxxx mN), and grid cell NS within that (representing the second digit 5xxxxxmE x6xxxxxm N), and as many remaining digits as are needed are reported, yielding an MGRS grid reference of 11U NS 949 361 (or 11U NS 9493 3617 or 11U NS ...
The Global Area Reference System (GARS) is a standardized geospatial reference system developed by the National Geospatial-Intelligence Agency (NGA) for use across the United States Department of Defense.
[10] [11] Grid Coordinates; for local areas. This part consists of an even number of digits, in this example, 23371 06519, and specifies a location within the 100 km grid square, relative to its lower-left corner. Split in half, the first part (here 23371), called the "easting", gives the displacement east of the left edge of the square; the ...
The GJ local grid. For example, on a GEOREF chart, Naval Air Station Patuxent River (38°17′10″N 76°24′42″W) / (38.286108, -76.4291704) is located (to the nearest minute) at position GJPJ3417. To locate the position from the coordinates, proceed as follows: Right from 180° longitude to longitude zone G
To reduce the number of figures needed to give a grid reference, the grid is divided into 100 km squares, which each have a two-letter code. National Grid positions can be given with this code followed by an easting and a northing both in the range 0 and 99999m. The projection formulae differ slightly from the Redfearn formulae presented here.
Given that every projection gives deformations, each country's needs are different in order to reduce these distortions. These national projections, or national Coordinate Reference Systems are officially announced by the relevant national agencies. The list below is a collection of available official national projected Coordinate Reference ...
