Official EPSG transformation from ETRS89 to WSPG-IRF

The EPSG Geodetic Parameter Dataset defines 1 transformation between ETRS89 (EPSG:4258) and WSPG-IRF (EPSG:10860). Its parameters, accuracy and area of use are listed below.

ETRS89 to WSPG-IRF (1)

EPSG:10861±0 m
Method:
NTv2
Area of use:
UK - Sneatonthorpe to Redcar
Scope:
Engineering survey and topographic mapping related to the Woodsmith mine project.

Grid file: TN15-ETRS89-to-WSPG-IRF.gsb

In conjunction with the WSPG-TM map projection (code 10862) applied to WSPG-IRF (code 10860), emulates the WSPG Snake projection. Applied to ETRS89 (as realized through the OSNet v2009) defines WSPG-IRF hence is errorless.

Frequently asked questions

How accurate is converting ETRS89 to WSPG-IRF?
The most accurate official EPSG transformation between these systems is accurate to about ±0 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation (including the grid-shift files listed below) in a desktop GIS.
Does my data leave the browser when I use this converter?
No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
