Detailed gravimetric quasigeoid QGZÚ-2013

Detailed gravimetric quasigeoid QGZÚ-2013 represents a transformation surface enabling transformation between altitudes H in the Baltic Vertical Datum – After Adjustment (Bpv) and ellipsoidal heights h in the European Terrestrial Reference System 1989 (ETRS89) /realization ETRF2000/ above the rotating ellipsoid Geodetic Reference System 1980 (GRS80). Data content creates height anomaly zeta expressed in the nodal points of regular grid (3'' x 3'') of geographical coordinates ETRS89. Height anomalies implements own transformation relationship that has the form h = H + zeta. Total mean square error of height anomaly is on the territory of the Czech Republic 1 cm, in the mountainous terrain and in border areas (up to 10 km from the border) can reach higher values, but not more than 3 cm. Quasigeoid model was computed using combined regional solution of linear gravimetric boundary value task for the correcting gravitational potential of the Earth, with the significant contribution of complete revised dataset of detailed points of gravimetric mapping of the Czech Republic performed in the frame of geophysical mapping between 1950 – 2010, and with the other data. Model enables application in a variety of geodetic works. It is especially aimed at the performing local transformations of heights in the given locality, for the expression of heights measured with GNSS technology or in other geometric methods in Bpv, for the mutual transformation of terrain heights between ETRS89 and Bpv in the given locality, etc.
