Transform Coordinates
Remarks
Parameter values from Lisbon to ETRS89 (1) (code 1655). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation. Replaced by Lisbon to WGS 84 (4) (code 1988).
Frequently Asked Questions
How do I convert Lisbon to WGS 84 coordinates?
Use the coordinate transformation tool above to convert Lisbon (EPSG:4207) to WGS 84 (EPSG:4326). 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 WGS 84 using Proj4js?
Use proj4.defs to define both EPSG:4207 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Lisbon to WGS 84 transformation?
This transformation (EPSG:1656) has an accuracy of 3m using the Position Vector transformation (geog2D domain) method. Area of use: Portugal - mainland - onshore.
