Name: ETRS89 to SCM22-IRF (1)
Method: NTv2
Grid Files: TN15-ETRS89-to-SCM22-IRF.gsb
Remarks: In conjunction with the SCM22-TM map projection (code 9971) applied to SCM22-IRF (code 9969), emulates the SCM22 Snake projection. Applied to ETRS89 (as realized through the OSNet v2009) defines SCM22-IRF hence is errorless.

Unit: metre
Geodetic CRS: ETRS89
Datum: European Terrestrial Reference System 1989 ensemble
Data source: EPSG
Information source: Landesamt für innere Verwaltung Mecklenburg-Vorpommern.
Revision date: 2024-01-04
Scope: Topographic mapping.
Remarks: Variant used in Germany of ETRS89 / UTM zone 31N (code 25831) in which axis order is reversed and easting has zone prefix. Does not distinguish between different realizations of ETRS89. For cadastre and engineering survey use DREF91/2016 CRS code 10286.
Area of use: Germany - onshore and offshore west of 6°E.
Coordinate system: Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: m.
