NAD83-98.gsb
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.

Engineering survey, topographic mapping.
State law of 2009 defines system in US survey feet: see CRS code 3566. An earlier state law of 1988 defining system in International feet was withdrawn in 2001. For onshore applications with an accuracy of better than 1m, replaced by NAD83(HARN) / SPCS.
Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
