Name: NAD83 to NAD83(CSRS) (1)
Method: NTv2
Grid Files: NAD83-98.gsb
Remarks: Uses NT method which expects longitudes positive west; EPSG GeogCRSs NAD83 (code 4269) and NAD83(CSRS) (code 4617) have longitudes positive east. Can be taken as an approximate transformation NAD83 to WGS 84 - see code 1696.

Revision date: 2002-07-13
Unit: metre
Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: Teranet Inc.
Revision date: 2010-11-01
Scope: Province-wide spatial data management.
Remarks: Data may sometimes be referenced to NAD83(CSRS) / Teranet Ontario Lambert (see CRS code 5321) which is then called "NAD83 / Teranet Ontario Lambert". At the scales involved the difference of under 2 metres between the two CRSs may not be significant.
Area of use: Canada - Ontario.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
