Method: NADCON5 (3D)
Grid Files: nadcon5.nad83_1993.nad83_2002.as.lat.trn.20160901.b nadcon5.nad83_1993.nad83_2002.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°.
