This map projection is a conformal, azimuthal projection. It is mainly used with a projection center in one of the poles. Then meridians appear as straight lines and cross latitudes at a right angle. Unlike the azimuthal equidistant projection, the distances in this projection are not displayed in correct proportions. It is often used as a hemisphere map like the Lambert Azimuthal Equal Area projection.
lon0/lat0 specifies the projection center, the optional
specifies the max distance from projection center (in degrees, < 180, default 90).
This projection can be displayed:
With map boundaries coinciding with longitude and latitude:
