Method: NADCON
Grid Files: cnhpgn.las cnhpgn.los
Remarks: Accuracy 67% confidence level. Uses NADCON method which expects longitudes positive west; EPSG GeogCRSs NAD83 (code 4269) and NAD83(HARN) (code 4152) have longitudes positive east. May be taken as approximate transformation NAD83-WGS 84 - see code 1739.

Revision date: 2023-01-17
Unit: US survey foot
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: 2008-06-19
Scope: Engineering survey, topographic mapping.
Remarks: State law defines use of US survey feet. Federal definition is metric - see code 32104. 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: ftUS.
