Name: ETRS89 to SMITB20-IRF (1)
Method: NTv2
Grid Files: TN15-ETRS89-to-SMITB20-IRF.gsb
Remarks: In conjunction with the SMITB20-TM map projection (code 10274) applied to SMITB20-IRF (code 10272), emulates the SMITB20 Snake projection. Applied to ETRS89 (as realized through the OSNet v2009) defines SMITB20-IRF hence is errorless.
