EPSG:1243

NAD27 to NAD83 (2)

Attributes

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.
