Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: OGP
Information source: Geodetic Service of Quebec. Contact alain.bernard@mrn.gouv.qc.ca
Revision date: 2000-10-19
Scope: Accuracy 1-2 metres.
Remarks: Uses NT method which expects longitudes positive west; EPSG GeogCRSs NAD83 (code 4269) and NAD83(CSRS98) (code 4140) have longitudes positive east. Can be taken as an approximate transformation NAD83 to WGS 84 - see code 1696.
Method: NTv2
Area of use: Canada - Quebec.
