Method: NADCON5 (2D)
Grid Files: nadcon5.nad27.nad83_1986.alaska.lat.trn.20160901.b nadcon5.nad27.nad83_1986.alaska.lon.trn.20160901.b
Remarks: Uses NADCON5 method which expects longitudes positive east in range 0-360°; source and target CRSs have longitudes positive east in range -180° to +180°. Accuracy at 67% confidence level is 0.5m onshore, 5m nearshore and undetermined farther offshore.
