Oblique Mercator

Oblique configurations of the cylinder give rise to the oblique Mercator projection. It is particularly useful when mapping regions of large lateral extent in an oblique direction. Both parallels and meridians are complex curves. The projection was developed in the early 1900s by several workers.

oc|oClon0/lat0/lonp/latp/scale[+v] or Oc|OClon0/lat0/lonp/latp/width[+v]

The projection is set with o or O. The central meridian is set by lon0/lat0. The projection pole is set by lonp/latp in option three. Align the y-axis with the optional +v. The figure size is set with scale or width.
