A DGGS is designed as a framework for information as distinct from conventional coordinate reference systems originally designed for navigation. For a grid-based global spatial information framework to operate effectively as an analytical system it should be constructed using cells that represent the surface of the Earth uniformly. [24]
Grid MORAs provide an obstacle clearance altitude within a latitude and longitude grid block, usually of one degree by one degree. [1] MORAs were created by Jeppesen and used on their airways charts. Some countries specify Minimum Enroute Altitudes (MEAs), minimum obstruction clearance altitudes (MOCAs), and Off Route Obstacle Clearance ...
Geocode cells of Geohash, with 8 (blue) and 9 (yellow) digits, a typical hierarchical grid, comparing with latitude-longitude (12 or more digits). A museum is a typical location to be pointed by a geocode, its gate need ~20 meters of precision.
The Open Geospatial Consortium has a spatial reference system standard based on the DERM called a [Discrete Global Grid] System (DGGS). According to OGC "a DGGS is a spatial reference system that uses a hierarchical tessellation of cells to partition and address the globe. DGGS are characterized by the properties of their cell structure, geo ...
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 coordinates provided.
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

The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids. [1] The Eastern Interconnection and the Western Interconnection are the largest. Three other regions include the Texas Interconnection, the Quebec Interconnection, and the Alaska Interconnection.
