Açıklamalar

In conjunction with the EWR2-TM map projection (code 9765) applied to EWR2-IRF (code 9763), emulates the EWR2 Snake projection. Applied to ETRS89 (as realized through the OSNet v2009 CORS) defines EWR2-IRF hence is errorless. In 2024 the EWR2 Grid (ETRS89 / EWR2 SnakeGrid) was extended eastwards as the EWR3 Grid (ETRS89 / EWR3 SnakeGrid). To the west of Bedford the EWR2 Grid is an exact subset of the EWR3 Grid; over this extent the EWR3 Grid replaces the EWR2 Grid. The EWR2 emulation file TN15-ETRS89-to-EWR2-IRF.gsb is a subset of the EWR3 emulation file TN15-ETRS89-to-EWR3-IRF.gsb (see CT code 10850).
