EPSG:1946

NAD83(CSRS) to WGS 84 (2)

Attributes

Geodetic CRS: NAD83(CSRS)

Datum: NAD83 Canadian Spatial Reference System

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: OGP

Information source: "Realization and Unification of NAD83 in Canada and the U.S. via the ITRF" by Cramer et al, IAG Proceedings, Section II, Munich, October 5-9, 1998; revised 11 March 1999.

Revision date: 2014-06-27

Scope: Geodesy.

Remarks: Approximation derived from tfm code 6864 ignoring time-dependent parameters and assuming ITRF96(1997.0) and WGS 84 can be considered the same within the accuracy of the transformation.

Method: Coordinate Frame rotation (geog2D domain)

Area of use: Canada - onshore and offshore - Alberta; British Columbia; Manitoba; New Brunswick; Newfoundland and Labrador; Northwest Territories; Nova Scotia; Nunavut; Ontario; Prince Edward Island; Quebec; Saskatchewan; Yukon.

Description: (-0.991, 1.9072, 0.5129, -1.25033e-07, -4.6785e-08, -5.6529e-08, 0.0)
