EPSG:2249

NAD83 / Massachusetts Mainland (ftUS)

Selected transformation

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. Can be taken as an approximate transformation NAD83 to WGS 84 - see code 1702.
