EPSG:8195 DEPRECATED

RT90 to WGS 84 (1)

Attributes

Geodetic CRS: RT90

Datum: Rikets koordinatsystem 1990

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

Information source: OGP

Revision date: 1999-04-22

Steps of transformation: 1437 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: Sweden - onshore and offshore.
