Learn how to convert geographic coordinates among different formats, systems and datums. Find formulas, methods and examples for latitude, longitude, height and other parameters.
Decimal degrees (DD) is a way of expressing latitude and longitude as decimal fractions of a degree, used in many geographic information systems and GPS devices. Learn how to convert DD to DMS notation, the precision of DD, and the examples of DD coordinates.
WKT (Well-known text representation of coordinate reference systems) is a standard format for describing and transforming spatial reference systems. Learn about the history, versions, syntax and examples of WKT from this Wikipedia article.
Learn how to obtain and add geographic coordinates to Wikipedia articles from various sources, such as maps, online services, directories, databases and calculators. Find out the preferred geotagging templates and the licensing information for different tools.
Learn how to measure and communicate positions on Earth using latitude and longitude, and how different geodetic datums affect the coordinates. Explore the history and standards of the geographic coordinate system and its applications in cartography and geodesy.
dms or decimal format is kept, format=dms can be added to decimal coordinates; negative coordinates followed by N or E are converted to positive coordinates followed by S or W; coordinates are not imported if: degrees are out of range (90°/180°) minutes or seconds >= 60; region doesn't start with [a-zA-Z] [a-zA-Z] type is not in list. A few ...
UTM is a map projection system that assigns coordinates to locations on the Earth's surface, ignoring altitude and treating the Earth as a perfect ellipsoid. It divides the Earth into 60 zones, each 6 degrees of longitude wide, and uses a transverse Mercator projection with a standard scale factor of 0.9996.
ISO 6709 is the international standard for representing latitude, longitude and altitude for geographic points. It defines the order, sign, units, display and encoding of coordinates, and the identification of coordinate reference systems.
