Remarks

Replaces WGS 84 to EGM96 height (1) (CT code 10084). Grid spacing is 2.5 arc-minutes. For a file with smaller (1 arc-minute) grid spacing (in principle more exactly representing the spherical harmonics) see CT code 3859. For reversible alternative see CT code 9704. An executable using spherical harmonics is available from the NGA site.
