EPSG:15851

NAD27 to WGS 84 (79)

Attributes

Geodetic CRS: NAD27

Datum: North American Datum 1927

Ellipsoid: Clarke 1866

Prime meridian: Greenwich

Data source: OGP

Information source: OGP

Revision date: 2006-03-06

Scope: Recommended for oil industry use in US Gulf of Mexico (GoM). Accuracy at 67% confidence level is 0.15m onshore, 5m nearshore and undetermined farther offshore.

Remarks: Transformation taken from NAD27 to NAD83 (1) (code 1241) assuming that NAD83 is equivalent to WGS 84 within the accuracy of this tfm. Uses NADCON method which expects longitudes positive west; EPSG CRS codes 4267 and 4326 have longitudes positive east.

Method: NADCON
