EPSG:26820 DEPRECATED

NAD83 / Minnesota Central (ftUS)

Selected transformation

Name: NAD83 to NAD83(CSRS)v2 (1)

Method: NTv2

Grid Files: NAD83-98.gsb

Remarks: Also found with file name NA83SCRS.GSB. Uses NT method which expects longitudes positive west; EPSG GeogCRSs NAD83 (code 4269) and NAD83(CSRS)v2 (code 8237) have longitudes positive east. Can be taken as an approximate CT NAD83 to WGS 84 - see code 1696.
