Name: NAD83 to NAD83(CSRS98) (1)
Method: NTv2
Grid Files: NAD83-98.gsb
Remarks: Uses NT method which expects longitudes positive west; EPSG GeogCRSs NAD83 (code 4269) and NAD83(CSRS98) (code 4140) have longitudes positive east. Can be taken as an approximate transformation NAD83 to WGS 84 - see code 1696.

Revision date: 2000-10-19
Unit: metre
Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: U.S. National Geodetic Survey, http://www.ngs.noaa.gov/
Revision date: 2008-02-08
Scope: Engineering survey, topographic mapping.
Remarks: State law defines use of US survey feet. Federal definition is metric - see code 26991. For applications with an accuracy of better than 3ft, replaced by NAD83(HARN) / SPCS.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
