EPSG:26708

NAD27 / UTM zone 8N

Selected transformation

Name: NAD83 to NAD83(CSRS98) (3)

Method: NTv2

Grid Files: AB_CSRS.DAC

Remarks: This gridded difference file AB_CSRS.DAC will need to be renamed to AB_CSRS.gsb to run in some software suites. Formats identical, but AB file is provincial fit only.
