# Projections

PyGMT support 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:

## Projection Table
