Decimal degrees (DD) is a notation for expressing latitude and longitude geographic coordinates as decimal fractions of a degree. DD are used in many geographic information systems (GIS), web mapping applications such as OpenStreetMap, and GPS devices. Decimal degrees are an alternative to using degrees-minutes-seconds notation. As with ...
Geographic coordinate conversion has applications in cartography, surveying, navigation and geographic information systems. In geodesy, geographic coordinate conversion is defined as translation among different coordinate formats or map projections all referenced to the same geodetic datum. [1]
The latitude is displayed first, and both coordinates are displayed in decimal degrees format. (in degrees only). Alternatively, any of the locations in My Places can be exported either as a KML file or GPX file , both of which embed the coordinates.
Blue Marble's first software product, the Geographic Calculator, [2] was developed in 1992 and released in 1993. The Geographic Calculator is a coordinate conversion library with a database of coordinate mathematical objects including projections, coordinate systems, datums, ellipsoids, linear and angular units. The tool is primarily used to ...
There was a short technical corrigendum (ISO 6709:2008/Cor 1:2009) released in 2009. [1] The third edition ISO 6709:2022 was published in 2022. [2] The second edition consists of a main part and eight annexes (Annexes A through H). The main part and Annexes A and C give encoding-independent general rules to define items to specify geographic ...
The reverse conversion is harder: given X-Y-Z can immediately get longitude, but no closed formula for latitude and height exists. See "Geodetic system." Using Bowring's formula in 1976 Survey Review the first iteration gives latitude correct within 10-11 degree as long as the point is within 10,000 meters above or 5,000 meters below the ellipsoid.

This template is designed to convert a set of Swiss coordinates into either the corresponding WGS84 decimal latitude or longitude.It is intended to facilitate the usage of geodata (see {{}}) in articles about subjects for which only Swiss coordinates are readily available.
