  • Germany - Sachsen. , accuracy 1.0 m, code 15954 (default) [grid]

Selected transformation

Method: NTv2

Grid Files: BETA2007.gsb

Remarks: Parameter values from taken DHDN to ETRS89 (8) (code 15948) as RD/83 and ETRS89 may be considered equivalent to DHDN and WGS 84 respectively within the accuracy of the transformation.

Information source: OGP

Revision date: 2021-09-23

Attributes

Unit: degree (supplier to define representation)

Geodetic CRS: RD/83

Datum: Rauenberg Datum/83

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

Information source: BKG via EuroGeographics. http://crs.bkg.bunde.de

Revision date: 2006-12-29

Scope: Cadastre, topographic mapping.

Remarks: Consistent with DHDN (CRS code 4314) at the 1-metre level. For low accuracy applications RD/83 can be considered the same as DHDN.

Area of use: Germany - Sachsen.

Coordinate system: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
