The projection from spheroid to a UTM zone is some parameterization of the transverse Mercator projection. The parameters vary by nation or region or mapping system. Most zones in UTM span 6 degrees of longitude, and each has a designated central meridian. The scale factor at the central meridian is specified to be 0.9996 of true scale for most ...
World files describing a map on the Universal Transverse Mercator coordinate system (UTM) use these conventions: D and B are usually 0, since the image pixels are usually made to align with the UTM grid; C is the UTM easting; F is the UTM northing; Units are always meters per pixel
Thomas–UTM: The λ expansions of Krüger were also confirmed by Paul Thomas in 1952: [12] they are readily available in Snyder. [13] His projection formulae, completely equivalent to those presented by Redfearn, were adopted by the United States Defence Mapping Agency as the basis for the UTM . [ 14 ]
Similar is Balthasart with standard parallels at 50°N/S and Tobler’s world in a square with standard parallels around 55.66°N/S. c. 1850: Central cylindrical: Cylindrical Perspective (unknown) Practically unused in cartography because of severe polar distortion, but popular in panoramic photography, especially for architectural scenes.
UTM is one such system, dividing the Earth into 60 longitude zones (and with UPS covering the Polar regions). UTM is widely used, and the coordinates approximately corresponds to meters north and east. However, as a set of map-projections it has inherent distortions, and thus most calculations based on UTM will not be exact. The crossing of ...

A projected coordinate system – also called a projected coordinate reference system, planar coordinate system, or grid reference system – is a type of spatial reference system that represents locations on Earth using Cartesian coordinates (x, y) on a planar surface created by a particular map projection.
