EPSG:1313

NAD27 to NAD83 (4)

Attributes

Geodetic CRS: NAD27

Datum: North American Datum 1927

Ellipsoid: Clarke 1866

Prime meridian: Greenwich

Data source: OGP

Information source: http://www.geod.nrcan.gc.ca/products/html-public/GSDapps/English/NTv2_Fact_Sheet.html

Revision date: 2018-04-20

Scope: Accuracy 1-2 metres.

Remarks: Uses NTv2 data files. Replaces NTv1 (transformation code 1312) except in Quebec. Input expects longitudes to be positive west; EPSG GeogCRS NAD27 (code 4267) and (code 4269) have longitudes positive east. May be used as tfm to WGS 84 - see code 1693.

Method: NTv2

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