EPSG:4855 DEPRECATED

ETRS89 / NTM zone 5

Selected transformation

Method: NTv2

Grid Files: gsb_2022.gsb

Remarks: In conjunction with the GSB-reconstruction projection (code 10261) applied to GSB-IRF (code 10260), enables transformation of coordinates between the historic Generalstaben in Bornholm and ETRS89. File is also available in GeoTIFF format (gsb_2022.tif).
