extends MapProjection

The Geostationary Satellite Projection

Adapted from https://github.com/OSGeo/proj.4/blob/4.9/src/PJ_geos.c

NOTE: Not all valid coordinates in this projection will transform to valid terrestrial coordinates, this is especially true of "Full Disk" earth coverages. If one must deal with coverages in this projection with generalized code which requires the coverage bounding-box coordinates to transform to valid terrestrial values consider clipping to a rectangle inscribing the ellipsoid.
