Derived in 2000 at 8 stations. Replaced by 2001 derivation (tfm code 1997). May be taken as approximate transformation to WGS 84 - see tfm code 1656,
Frequently Asked Questions
How do I convert Lisbon to ETRS89 coordinates?
Use the coordinate transformation tool above to convert Lisbon (EPSG:4207) to ETRS89 (EPSG:4258). Enter your source coordinates and click Transform. This uses the Position Vector transformation (geog2D domain) method with 3m accuracy.
How do I transform Lisbon to ETRS89 using Proj4js?
Use proj4.defs to define both EPSG:4207 and EPSG:4258, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Lisbon to ETRS89 transformation?
This transformation (EPSG:1655) has an accuracy of 3m using the Position Vector transformation (geog2D domain) method. Area of use: Portugal - mainland - onshore.
