Dataset description

The product consists of the two parts 1 — Height Grid plus Geoid The height grid plus geoid enables the transformation of ellipsoidal heights in the ERTS89/GRS80 system at heights of the MGI with reference Adria 1875 (use heights H.ü.A.) in one step. Suitable for transforming heights, e.g. from laser scanning data available in the ETRS89/GRS80 system, in operating heights of the MGI (at level of levelling heights). 2 — Correction values of the heights of the location points to the height grid The correction values kLFP for the height grid are used to correct the usage heights contained in the point maps of the positional fixed points in order to achieve conformity with the usage heights derived by means of GNSS measurements, geoidundulations and height grids. Suitable for adjusting operating heights (e.g. laser scanning) created with the height grid plus geoid from ellipsoidal heights, with the operating heights of the positional fixed points.
