Known are the heights of each pixel in the master (line,pixel) system.
The point P(x,y,z) corresponding to a (line,pixel) is computed with
the 3 equations (see Annex D) in such a way that
it lies on an ellipsoid of height h above the refernce ellipsoid.
When these coordinates are known, the equations of Bowring are used to
transform them to an ellipsoid system
. The
semimajor axis is denoted by a, and the semiminor axis is
denoted by b. The squared first eccentricity by:
