EPSG:1493

NAD83 to NAD83(HARN) (20)

Attributes

Geodetic CRS: NAD83

Datum: North American Datum 1983

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: OGP

Information source: US Coast & Geodetic Survey www.ngs.noaa.gov NADCON readme file

Revision date: 2004-04-27

Scope: Geodetic survey. Accuracy 0.05m at 67% confidence level.

Remarks: 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 1729.

Method: NADCON

Area of use: United States (USA) - North Dakota.
