Remarks

Transformation is considered errorless when deriving LSG2025 coordinates using OSNet v2009. Note: before 2016 the same transformation parameter values were applied to OSNet v2001 coordinates to derive LSG coordinates. The horizontal differences between coordinates derived using OSNet v2001 and coordinates derived using OSNet v2009 average approximately 12mm in Eastings and 2mm in Northings in the Greater London area.

Frequently Asked Questions

What is the accuracy of the ETRS89-GBR [OSNet v2009] to Xrail84 transformation?

This is an exact transformation (EPSG:10996) with no loss of precision (0m accuracy) using the Coordinate Frame rotation (geocentric domain) method. Area of use: UK - Greater London.
