Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: OGP
Information source: OGP
Revision date: 2001-08-15
Scope: Approximation at the +/- 1m level.
Remarks: Parameter file is from NAD83 to NAD83(CSRS) (3) (code 1849) assuming that NAD83(CSRS) is equivalent to WGS 84 within the accuracy of the transformation. This file AB_CSRS.DAC will need to be renamed to AB_CSRS.gsb to run in some sodtware.
Method: NTv2
Area of use: Canada - Alberta.
