Name: NAD83 to NAD83(CSRS) (1)
Method: NTv2
Grid Files: NAD83-98.gsb
Remarks: Uses NT method which expects longitudes positive west; EPSG GeogCRSs NAD83 (code 4269) and NAD83(CSRS) (code 4617) have longitudes positive east. Can be taken as an approximate transformation NAD83 to WGS 84 - see code 1696.
