EPSG:1997

Lisbon to ETRS89 (2)

Attributes

Geodetic CRS: Lisbon

Datum: Lisbon 1937

Ellipsoid: International 1924

Prime meridian: Greenwich

Data source: EPSG

Information source: Instituto Portugues de Cartografia e Cadastro via EuroGeographics; http://crs.bkg.bund.de/crs-eu/ Also given to greater precision (but no more accuracy) using the coordinate frame method at the IGEO website www.igeo.pt

Revision date: 2020-03-14

Scope: Transformation of coordinates at 2m level of accuracy.

Remarks: Derived in 2001. Replaces Lisbon to ETRS89 (1) (code 1655). Also given to greater precision but no more accuracy on ICC web site using Coordinate Frame method. Replaced by Lisbon to ETRS89 (3) (code 5038).

Method: Position Vector transformation (geog2D domain)

Area of use: Portugal - mainland - onshore.
