Selected transformation

Name: American Samoa 1962 to NAD83(HARN) (3)

Method: NADCON5 (2D)

Grid Files: nadcon5.as62.nad83_1993.as.lat.trn.20160901.b nadcon5.as62.nad83_1993.as.lon.trn.20160901.b

Remarks: Uses NADCON5 method which expects longitudes positive east in range 0-360°; EPSG source and target CRSs have longitudes positive east in range -180° to +180°.
