Geodetic CRS: DHDN
Datum: Deutsches Hauptdreiecksnetz
Ellipsoid: Bessel 1841
Prime meridian: Greenwich
Data source: EPSG
Information source: Institute for Cartography and Geodesy; Leipzig via EuroGeographics; http://crs.bkg.bund.de/crs-eu/
Revision date: 2020-03-14
Scope: Transformation of coordinates at 3m level of accuracy.
Remarks: Mean of 109 stations. Replaces DHDN to ETRS89 (1) (tfm code 1309). May be taken as approximate transformation DHDN to WGS 84 - see code 1777.
Method: Position Vector transformation (geog2D domain)
