EPSG:1703

NAD27 to WGS 84 (32)

Attributes

Geodetic CRS: NAD27

Datum: North American Datum 1927

Ellipsoid: Clarke 1866

Prime meridian: Greenwich

Data source: EPSG

Information source: OGP

Revision date: 2021-11-04

Scope: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.

Remarks: Parameter file is from NAD27 to NAD83(CSRS)v2 (2) (code 9886) assuming that NAD83(CSRS)v2 is equivalent to WGS 84 within the accuracy of the transformation.

Method: NTv2

Area of use: Canada - Saskatchewan.
