  2. Geographic coordinate conversion - Wikipedia

    en.wikipedia.org/wiki/Geographic_coordinate...

    A coordinate system conversion is a conversion from one coordinate system to another, with both coordinate systems based on the same geodetic datum. Common conversion tasks include conversion between geodetic and earth-centered, earth-fixed ( ECEF ) coordinates and conversion from one type of map projection to another.

  3. 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]

    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. Universal Polar Stereographic coordinate system, used at the North and South poles. Open Location Code, a hierarchical zoned system

    North of 84°N, UPS North is used, and the west half-circle is Y, the east one is Z; see figure 4. Since the letters A, B, Y, and Z are not used for any latitude bands of UTM, their presence in an MGRS coordinate, with the omission of a zone number, indicates that the coordinates are in the UPS system.

    As such, they are often better served by a local Cartesian coordinate system, in which the coordinates represent actual distance units on the ground, using the same units of measurement from two perpendicular coordinate axes. [1] [2] [3] This can improve human comprehension by providing reference of scale, as well as making actual distance ...

    en.wikipedia.org/wiki/Blue_Marble_Geographics

    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.

  9. Open Location Code - Wikipedia

    en.wikipedia.org/wiki/Open_Location_Code

    It was developed at Google's Zürich engineering office, [2] and released late October 2014. [3] Location codes created by the OLC system are referred to as "plus codes". Open Location Code is a way of encoding location into a form that is easier to use than showing coordinates in the usual form of latitude and longitude. Plus codes are ...
