The main advantage of this projection is that distances from the projection center are displayed in correct proportions. Also directions measured from the projection center are correct. It is very useful for a global view on locations that lie within a certain distance or for comparing distances of different locations relative to the projection center.
lon0/lat0 specifies the projection center. The optional parameter
horizon specifies the max distance to the projection center (i.e. the
visibile portion of the rest of the world map) in degrees <= 180° (default 180°).
