EPSG:8234 DEPRECATED

DHDN to WGS 84 (1)

Attributes

Geodetic CRS: DHDN

Datum: Deutsches Hauptdreiecksnetz

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

Information source: OGP

Revision date: 1998-06-30

Steps of transformation: 1309 1149

Scope: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.

Remarks: Approximation at the +/- 1m level assuming that ETRF89 is equivalent to WGS 84.

Area of use: Germany - states of former West Germany onshore - Baden-Wurtemberg, Bayern, Bremen, Hamburg, Hessen, Niedersachsen, Nordrhein-Westfalen, Rheinland-Pfalz, Saarland, Schleswig-Holstein.
