ISO 6709, Standard representation of geographic point location by coordinates, is the international standard for representation of latitude, longitude and altitude for geographic point locations. The first edition ( ISO 6709:1983 ) was developed by ISO/IEC JTC 1 /SC 32.
Module:Location map/data/USA Midwest is a location map definition used to overlay markers and labels on an equirectangular projection map of USA Midwest. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
Module:Location map/data/USA Southeast is a location map definition used to overlay markers and labels on an equirectangular projection map of Southeastern United States. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
Name used in the default map caption; image = U.S. - Los Angeles Metropolitan Area location map.svg The default map image, without "Image:" or "File:" top = 34.86 Latitude at top edge of map, in decimal degrees; bottom = 33.28 Latitude at bottom edge of map, in decimal degrees; left = -119.1 Longitude at left edge of map, in decimal degrees ...
Module:Location map/data/Canada is a location map definition used to overlay markers and labels on a Lambert conformal conic projection map of Canada. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
The first level of GEOREF divides the world into quadrangles each measuring 15 degrees of longitude by 15 degrees of latitude; this results in 24 zones of longitude and 12 bands of latitude. A longitude zone is identified by a letter from A to Z (omitting I and O) starting at 180 degrees and progressing eastward through the full 360 degrees of ...
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.
When it is undefined, the elevation is assumed to be the altitude of the latitude-longitude point, that is its height (or negative depth) relative to the geoid (i.e. "ground elevation"). A point with a measure "altitude=0" is, however, not to be confused with an undefined value: it refers to an altitude of 0 meters above the geoid.
