Reference system CHTRS95

The new global reference system for the Swiss national survey LV95 which is identical to ETRS89 with the point at the time t0 = 1993.0. The system includes the definition of the reference ellipsoid (GRS80) fixed in position and orientation to Z0 and uses the global map projection Universal Transverse Mercator (UTM). CHTRS95 also defines a new, theoretically rigorous orthometric height system with respect to the gravity field whose point of origin Z0 (Geostation Zimmerwald) has the orthometric height H0 = 897.8027 m (derived from the UELN95/98).
