This class describes a horizontal datum.
Library: ilvmaps
A horizontal datum is defined by a translation of the ellipsoid. Usually, the translation is performed so that the translated ellipsoid is tangent to the geoid surface in the region of interest. An IlvHorizontalShiftDatum
object is based on the shift parameters relative to the WGS84 datum used by the Molodensky formula.
