EPSG:2283

NAD83 / Virginia North (ftUS)

Available transformations
to EPSG:4326

Selected transformation

Method: NADCON

Grid Files: vahpgn.las vahpgn.los

Remarks: Parameter files are from NAD83 to NAD83(HARN) (27) (code 1500) assuming that NAD83(HARN) is equivalent to WGS 84 within the accuracy of the transformation.
