TN15-ETRS89-to-RBEPP12-IRF.gsb
In conjunction with the RBEPP12-LCC map projection (code 10279) applied to RBEPP12-IRF (code 10277), emulates the RBEPP12 Snake projection. Applied to ETRS89 (as realized through the OSNet v2009) defines RBEPP12-IRF hence is errorless.

Pan-European medium scale conformal mapping.
ETRS89-LCC (CRS code 3034) used for conformal mapping at 1:500,000 and smaller scales. ETRS89-LAEA (CRS code 3035) used for statistical applications at all scales. See ETRS89 / UTM zone 31N (CRS code 25831) for CRS with preferred east-north axis order.
Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: m.
