General stereographic projection

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.

slon0/lat0[/horizon]/scale or Slon0/lat0[/horizon]/width

• s or S: Sets the projection type.

• lon0/lat0: Sets the projection center.

• horizon: Sets the maximum distance from the projection center in degrees (< 180°) [Optional, default is 90°].

• scale or width: Sets the map size.
