EPSG:10175 - DoPw22-IRF

  • United Kingdom (UK) code 10181 (default) [grid]

Selected transformation

Method: NTv2

Grid Files: TN15-ETRS89-to-DoPw22-IRF.gsb

Remarks: In conjunction with DoPw22-TM map projection (code 10182) applied to DoPw22-IRF (code 10175), emulates the DoPw22 Snake projection. Applied to ETRS89 (as realized through the OSNet v2009) defines DoPw22-IRF hence is errorless.
