Transformation of GPS results,mple are obtained in the same reference frame. However, the surveyor is not, usually, interested in computing the coordinates of the terrestrial points in a global frame. Rather, the results are preferred in a local coordinate frame either as geodetic (i.e., ellipsoidal) coordinates, as plane coordi
