Oblique Mercator, 1: origin and azimuth
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.
oa|oAlon0/lat0/azimuth/scale[+v] or Oa|OAlon0/lat0/azimuth/width[+v]
The projection is set with o or O. The pole is set in the northern hemisphere with a or the southern hemisphere with A. The central meridian is set by lon0/lat0. The oblique equator is set by azimuth. Align the y-axis with the optional +v. The figure size is set with scale or width.
import pygmt fig = pygmt.Figure() # Using the origin and azimuth fig.coast( projection="Oa-120/25/-30/6c+v", # Set bottom left and top right coordinates of the figure with "+r" region="-122/35/-107/22+r", frame="afg", land="gray", shorelines="1/thin", water="lightblue", ) fig.show()
