Use of standard codes facilitates the interchange of machine-readable data from agency to agency within the federal community and between federal offices and state and local groups. These codes are also used by some companies as a coding standard as well, especially those that must deal with federal, state and local governments for such things ...
So, the most general case is a table of standard names and the corresponding standard codes (and its official geometries). Germany (DE) with each first-level administrative subdivision labelled with the second part of its ISO 3166-2 code. The 21 top-level 2-digit "region" of hydrologic unit boundaries, using the HUC geocode conventions.
1234 5678 (numerical location; easting is 1234 and northing is 5678, in this case specifying a location with 10 m resolution) An MGRS grid reference is a point reference system. When the term 'grid square' is used, it can refer to a square with a side length of 10 km (6 mi), 1 km, 100 m (328 ft), 10 m or 1 m, depending on the precision of the ...

This is a list of heritage NATO country codes. Up to and including the seventh edition of STANAG 1059, these were two-letter codes (digrams). The eighth edition, promulgated 19 February 2004, and effective 1 April 2004, replaced all codes with new ones based on the ISO 3166-1 alpha-2 codes. Additional codes cover gaps in the ISO coverage, deal ...
A geocode is a geographical code to identify a point or area at the surface of the earth. Subcategories This category has the following 14 subcategories, out of 14 total.
The shortness is the key differentiating factor between mapcodes and other location references; [1] more densely populated areas are designated with shorter (4 character) codes. The brevity of mapcodes was achieved through a combination of several ideas: Codes need only be accurate enough for human, everyday use.
Until the adoption of WGS 84 as the official geodetic datum of the Maidenhead locator system in 1999, [2] operators had usually specified their location based on their local national datum. Consequently, stations very near the edges of squares (at denoted precision) may have changed their locators when changing over to the use of WGS 84.
