  Grid reference - Wikipedia, the free encyclopedia
A grid reference is a standard method for the location of a point on a map.
Grids may be arbitrary, or based on specific distances -- for example the United Kingdom Ordnance Survey maps use a 1 kilometre square grid spacing.
The convention is to add these to the 4 figure grid reference after the 2 digits describing the same coordinate axis, and thus our six figure grid reference for the church becomes 696018.

 British national grid reference system - Wikipedia, the free encyclopedia
The Ordnance Survey (OS) devised the national grid reference system, and it is heavily used in their survey data, and in maps (whether published by the Ordnance Survey or commercial map producers) based on those surveys.
For example, the grid reference of the 100 m square containing the summit of Ben Nevis is NN 166 712.
Grid references may also be quoted as a pair of numbers: eastings then northings in metres.

Grids may be arbitrary, or based on specific distances -- for example the 1:50000 Ordnance Survey maps use a 1km square grid spacing.

Grid is a specific Data which is n-dimensional.
It is specified by the number of grid cells, the limits (in some rectangular sense), and the Geometry on which those limits are imposed.
Grids may also be constructed such that they have a different Geometry from their parent region or particle.

 SurvivalIQ Handbook: Land Navigation - Grids - United states army military grid reference system
In the south polar area, the letter A is the grid zone designation for the area west of the 0-180° meridian, and B for the area to the east.
The military grid reference of a point consists of the numbers and letters indicating in which of these areas the point lies, plus the coordinates locating the point to the desired position within the 100,000-meter square.
Therefore, the first grid line east of the south-west corner is labeled 689000m E. The principal digits, 89, identify the line for referencing points in the easterly direction (Figure 4-13).

 Single QIAC
Note that to prevent the grid from crossing each other on a boundary, the locations on the domain boundaries and the points nearest to the boundaries are not changed by the inverse interpolation.
Because we modify the grid point locations only on the four lines, where the edges of quadrilateral lie, and the domain boundaries, the grid we generate after this step is very irregular.
Rather than have the algorithm fail when this occurs, we define the reference vertices sequentially by binding the vertex is closest to a reference point to that point and eliminating it for consideration as a reference point for any other vertices.

 Universal Transverse Mercator (UTM) and Military Grid Reference System (MGRS) – FMNH
In each even-numbered 6° grid zone, the some lettering sequence is advanced five letters to F, continued sequentially through V and followed by A through V. The advancement or staggering of row letters for the even-numbered zones lengthens the distance between 100,000-meter squares of the same identification.
Determination of 100,000-meter grid square identification is further complicated by the use of different ellipsoids.

 Understanding Ordnance Survey Grid References
The British National Grid provides a much simpler way to specify the position of any feature on an OS map, from a city down to the smallest farm or church or stream.
To simplify the system, there is a grid of larger squares, each 100 kilometres by 100 kilometres (roughly 60 miles by 60 miles), which each have a two-letter designation such as TQ, SV, NA or HZ.
A grid reference such as SD4198 specifies the position of a place to the nearest kilometre.

 1-Introducing the United States National Grid
The United States National Grid is a nonproprietary alphanumeric referencing system derived from the Military Grid Reference System (MGRS) that is being promoted to increase the interoperability of location services appliances with printed map products by providing a nationally consistent grid reference system.
The objective of this U.S. National Grid standard is to create a more interoperable environment for developing location-based services within the United States and to increase the interoperability of location services appliances with printed map products by establishing a nationally consistent grid reference system as the preferred grid for NSDI applications.
The U.S. National Grid is based on universally-defined coordinate and grid systems and can, therefore, be easily extended for use world-wide as a universal grid reference system.

 EGA's Reference Model Beckons Enterprises to Grid
The model, downloadable from the EGA's site, includes three vendor-neutral components: a common lexicon of grid terms, a model that classifies the management and life cycles of the components required for enterprise grids, and a set of use cases that demonstrate the requirements for enterprise grid computing in specific enterprise scenarios.
That's where the Reference Model comes in, he said, it being a tool for understanding sets of components that comprise the data center, along with their relationships with each other and what Strong referred to as their life cycles—in other words, how components fit in to existing data center architectures.
Strong said the Reference Model's lexicon is aimed at clearing the haze around the collection of terms used to talk about grid.
