NAD83 / BLM 15N (ftUS)

Canada , accuracy 0.1 m, code 9119 (default) [grid]
Canada - Alberta. , accuracy 1.5 m, code 9244 [grid]

Selected transformation

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.
