EPSG:2284

NAD83 / Virginia South (ftUS)

Available transformations
to EPSG:4152
EPSG:4152 - NAD83(HARN)

Selected transformation

Method: NADCON

Grid Files: mohpgn.las mohpgn.los

Remarks: Uses NADCON method which expects longitudes positive west; EPSG GeogCRSs NAD83 (code 4269) and NAD83(HARN) (code 4152) have longitudes positive east. May be taken as approximate transformation NAD83-WGS 84 - see code 1711.
