The grid is there so that on most occasions objects align up, but if for example you want to centre two complex objects, you may find that no suitable grid point exists and it is impossible to drag the objects into the correct position. The image above shows the effect of a snap grid. Each diamond is one grid position away from the last.
What3words divides the world into a grid of 57 trillion 3-by-3-metre (10 ft × 10 ft) squares, each of which has a three-word address. The company says they do their best to remove homophones and spelling variations; [25] however, at least 32 pairs of English near-homophones still remain.
Military Grid Reference System is the geocoordinate standard used by NATO militaries for locating points on Earth. Universal Transverse Mercator coordinate system is a map projection system for assigning coordinates to locations on the surface of the Earth. the Maidenhead Locator System, popular with radio operators.
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.
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 ...
Extensions to the above notation allow the GEOREF system to be used to designate an area around a reference point. This is achieved by adding an area designation to a base GEOREF co-ordinate. The area designation can be the letter S, to specify the sides of a rectangle (separated by the letter X); or the letter R, to specify the radius of a circle.
A grid bearing (also known as grid azimuth) is measured in relation to the fixed horizontal reference plane of grid north, that is, using the direction northwards along the grid lines of the map projection as a reference point.
The term is generally applied to any item used to mark a point as an elevation reference. Frequently, bronze or aluminum disks are set in stone or concrete, or on rods driven deeply into the earth to provide a stable elevation point. If an elevation is marked on a map, but there is no physical mark on the ground, it is a spot height.
