Name: NAD83 to NAD83(CSRS)v4 (3)
Method: NTv2
Grid Files: AB_CSRS.DAC
Remarks: This gridded difference file AB_CSRS.DAC may need to be renamed to AB_CSRS.gsb or AB_CSRSV4.gsb to run in some software. Formats identical, but AB file is provincial fit only. Can be taken as an approximate transformation NAD83 to WGS 84 - see code 1702.
