Dataset description

The transformation model NTv2 Bayern (2011) is based on 37,000 bases in Bavaria (nearly the whole of the TP field 1-4, which can be measured using GNSS method. Order), has a grid width of 0.5 in length and width and offers a transformation accuracy of 1.3 cm (1 Sigma). NTv2 Bayern (2011) is thus the official transition between the ETRS89/DREF91 (SAPOS) and the DHDN90 in the realisation of the trigonometric fixed point field. The data is optionally output in NTv2 (ASCII), NTv2 (binary) and XML formats. Another reference system is the DHDN (geographic 2D) (EPSG:4314). Please note that the new height reference system DHHN16 will be introduced on 30.06.2017.
