Selected transformation

Method: Position Vector transformation (geog2D domain)

Remarks: Derived in 2001 at 31 points of the German GPS Network DREF in former East Germany. Although for high accuracy limited to Saxony, may be taken as approximate transformation between DHDN and WGS 84 for all former East German states - see code 15869.

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
