EPSG:1631

ED50 to WGS 84 (27)

Attributes

Geodetic CRS: ED50

Datum: European Datum 1950

Ellipsoid: International 1924

Prime meridian: Greenwich

Data source: EPSG

Information source: OGP

Revision date: 2020-03-14

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: Parameter values from ED50 to ETRS89 (6) (code 1630). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation.

Method: Position Vector transformation (geog2D domain)

Area of use: Spain - Balearic Islands.

Description: (-181.5, -90.3, -187.2, 0.144, 0.492, -0.394, 17.57)
