NAD83 / California zone 6

Available transformations
to EPSG:4152

Selected transformation

Method: NADCON5 (2D)

Grid Files: nadcon5.nad83_1986.nad83_1992.alaska.lat.trn.20160901.b nadcon5.nad83_1986.nad83_1992.alaska.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°.
