Since, in the UK at least, a 6-figure grid reference identifies a square of 100-metre sides, an 8-figure reference would identify a 10-metre square, and a 10-digit reference a 1-metre square. In order to give a standard 6-figure grid reference from a 10-figure GPS readout, the 4th, 5th, 9th and 10th digits must be omitted, so it is important ...
The most common usage is the six figure grid reference, employing three digits in each coordinate to determine a 100 m square. For example, the grid reference of the 100 m square containing the summit of Ben Nevis is . (Grid references may be written with or without spaces; e.g., also NN166712.)
The intersection of a UTM zone and a latitude band is (normally) a 6° × 8° polygon called a grid zone, whose designation in MGRS is formed by the zone number (one or two digits – the number for zones 1 to 9 is just a single digit, according to the example in DMA TM 8358.1, Section 3-2, [1] Figure 7), followed by the latitude band letter ...
A location can be indicated to varying resolutions numerically, usually from two digits in each coordinate (for a 1 km (0.62 mi) square) through to five (for a 1 m (3 ft 3 in)) square; the most common usage is the six figure grid reference, employing three digits in each coordinate to determine a 100 m (330 ft) square.
The first three parameters are all required, and must be in the order given: OS Grid ref: in the form AB123456 (for example).Degree of accuracy is flexible, but for most purposes a six figure reference is good, identifying a 100m square. 8 figures identifies a 10-metre square.
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
Full "ten figure" grid reference Ireland: i888_999: Letter 'i' followed by two decimal numbers - eastings then northings in metres separated by an underscore R: Standard grid references. In each of these cases, the actual coordinates passed to the map sources page will be the centre of the square that the grid ref defines R16 R1267 R123678 ...
The equivalent Irish Grid co-ordinate for the same location is: 315904, 234671 or O1590434671. The Spire of Dublin example provides a fix for a location that is accurate to 1 metre. With ITM it is possible to give a more accurate co-ordinate for a given location by using a decimal point after the initial six figure easting and northing.
