Available transformations

Selected transformation

Method: NTv2

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.
