EPSG:32047

NAD27 / Virginia South

Selected transformation

Method: NTv2

Grid Files: NB2783v2.gsb

Remarks: Introduced in 2011. Precision of 20 cm in area covered by the input data set and 40 cm anywhere else, with the exception of the northwest area of the province (near the border with Quebec) where the precision deteriorates to 80 cm.
