Projections
PyGMT supports many map projections. Use the projection parameter to specify which
one you want to use in all plotting methods. The projection is specified by a one-letter
code along with (sometimes optional) reference longitude and latitude and the
width of the map (for example, Alon0/lat0[/horizon]/width). The map
height is determined based on the region and projection.
These are all the available projections:
Azimuthal Projections
Conic Projections
Cylindric Projections
Miscellaneous Projections
Non-geographic Projections
