The transverse Mercator map projection (TM, TMP) is an adaptation of the standard Mercator projection. The transverse version is widely used in national and international mapping systems around the world, including the Universal Transverse Mercator .
Web Mercator: Cylindrical Compromise Google: Variant of Mercator that ignores Earth's ellipticity for fast calculation, and clips latitudes to ~85.05° for square presentation. De facto standard for Web mapping applications. 1822 Gauss–Krüger = Gauss conformal = (ellipsoidal) transverse Mercator: Cylindrical Conformal Carl Friedrich Gauss
The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth. Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid. However, it differs from ...
A Mercator map can therefore never fully show the polar areas (but see Uses below for applications of the oblique and transverse Mercator projections). The Mercator projection is often compared to and confused with the central cylindrical projection , which is the result of projecting points from the sphere onto a tangent cylinder along ...
Mercator projection (conformal cylindrical projection) Mercator projection of normal aspect (Every rhumb line is drawn as a straight line on the map.) Transverse Mercator projection. Gauss–Krüger coordinate system (This projection preserves lengths on the central meridian on an ellipsoid) Oblique Mercator projection
A coordinate system conversion is a conversion from one coordinate system to another, with both coordinate systems based on the same geodetic datum.
Modern national mapping systems typically employ a transverse Mercator or close variant for large-scale maps in order to preserve conformality and low variation in scale over small areas. For smaller-scale maps, such as those spanning continents or the entire world, many projections are in common use according to their fitness for the purpose ...
