Transverse Mercator

The transverse Mercator was invented by Johann Heinrich Lambert in 1772. In this projection the cylinder touches a meridian along which there is no distortion. The distortion increases away from the central meridian and goes to infinity at 90° from center. The central meridian, each meridian 90° away from the center, and equator are straight lines; other parallels and meridians are complex curves.

tlon0/[lat0/]scale or Tlon0/[lat0/]width

The projection is set with t or T. The central meridian is set by lon0, the latitude of the origin is set by the optional lat0, and the figure size is set with scale or width.
