to EPSG:4140

Selected transformation

Method: NTv2

Grid Files: CGQ77-98.gsb

Remarks: Uses NT method which expects longitudes positive west; EPSG GeogCRSs NAD27(CGQ77) (code 4609) and NAD83(CSRS98) (code 4140) have 1691longitudes positive east. Can be taken as an approximate transformation NAD27(CGQ77) to WGS 84 - see code 1691.
