Conversion of coordinates and map positions among different map projections reference to the same datum may be accomplished either through direct translation formulas from one projection to another, or by first converting from a projection to an intermediate coordinate system, such as ECEF, then converting from ECEF to projection . The formulas ...
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.
Conversion: Many scientific calculators (including the one that comes with Windows, use dms and inv dms) can convert coordinates. The Getty Thesaurus of Geographic Names: Name search: Allows you to find coordinates with a place name search. Licensing: Geonet Names Server (GNS) Name search
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
A WKT format is defined to describe the operation methods and parameters used to convert or transform coordinates between two different coordinate reference systems. The WKT 1 and WKT 2 formats are incompatible regarding coordinate operations, because of differences in the modelling. [13]
European Terrestrial Reference System 1989 (ETRS89) Military grid reference system, a variant of UTM designed to simplify transfer of coordinates. Modified transverse Mercator, a variation of UTM used in Canada with zones spaced 3° of longitude apart as opposed to UTM's 6°. Transverse Mercator projection, the map projection used by UTM.
A DMS value is converted to decimal degrees using the formula: = + + For instance, the decimal degree representation for 38° 53′ 23″ N, 77° 00′ 32″ W (the location of the United States Capitol) is 38.8897°, -77.0089°
British national grid references of the Ordnance Survey use its own OSGB36 datum, which is correct for use in national grid references; the correct transformations will automatically be applied when national grid coordinates are used in {} tags. However, OSGB36 latitude/longitude coordinates should not be used anywhere in Wikipedia; please use ...
