NAD83 / Mississippi TM

Available transformations
to EPSG:4326
EPSG:4326 - WGS 84

Selected transformation

Method: NTv2

Grid Files: AB_CSRS.DAC

Remarks: Parameter file is from NAD83 to NAD83(CSRS)v4 (3) (code 9244) assuming that NAD83(CSRS)v4 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 software.
