4 Transformation of EOV coordinates to HD-72 Datum

This is the transformation from EOV plane coordinates to the IUGG GRS 1967 reference ellipsoid in HD-72 (see Chapter 2):

(XEOV , YEOV) - ( , ) and ( , ) - ( , )

If necessary, another step is to be performed. This is the transformation from the above ellipsoidal coordinates to the three-dimensional rectangular ones as it follows:

( , ) , h = H+N) - (X, Y, Z)

X = (RN + h) x cos x cos
Y = (RN + h) x cos x sin
Z = [RN x (1-e2) + h] x sin
