public abstract class Orthographic

extends PlanarProjection

Orthographic Projection. This is a perspective azimuthal (planar) projection that is neither conformal nor equal-area. It resembles a globe and only one hemisphere can be seen at a time, since it is a perspectiove projection from infinite distance. While not useful for accurate measurements, this projection is useful for pictorial views of the world. Only the spherical form is given here.

NOTE: formulae used below are from a port, to java, of the 'proj4' package of the USGS survey. USGS work is acknowledged here.
