Geodetic CRS: NAD27
Datum: North American Datum 1927
Ellipsoid: Clarke 1866
Prime meridian: Greenwich
Data source: OGP
Information source: US Coast & Geodetic Survey www.ngs.noaa.gov
Revision date: 2006-12-26
Scope: Accuracy at 67% confidence level is 0.5m onshore, 5m nearshore and undetermined farther offshore.
Remarks: Uses NADCON method which expects longitudes positive west; EPSG GeogCRS NAD27 (code 4267) and NAD83 (code 4269) have longitudes positive east. May be used as transformation to WGS 84 - see NAD27 to WGS 84 (85) (code 15864).
Method: NADCON
Area of use: United States (USA) - Alaska including EEZ.
