EPSG:3090

NAD83(HARN) / Kentucky Single Zone

Selected transformation

United States (USA)

code 1900

Accuracy 1.0 m
7 parameters

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Approximation derived ignoring time-dependent parameters and assuming ITRF94(1996.0) and WGS 84, plus NAD83(CORS94) and NAD83(HARN), can be considered the same within the accuracy of the transformation. Replaced by NAD83(HARN) to WGS 84 (3) (code 1901).

Information source: US National Geodetic Survey http://www.ngs.noaa.gov/CORS/Derivation.html

Revision date: 2017-10-16

Attributes

Unit: metre

Geodetic CRS: NAD83(HARN)

Datum: NAD83 (High Accuracy Reference Network)

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: OGP

Information source: National Geodetic Survey (private communication) and Kentucky Division of Geographic Information, http://ngs.ky.gov/pdf-ppt/BB/KY_Single-Zone_Article.pdf

Revision date: 2007-04-20

Scope: Used for spatial data presentation for whole state.

Remarks: State law defines system in US survey feet. See code 3091 for equivalent non-metric definition. Replaces NAD83 / KY1Z for applications with an accuracy of better than 1m. Replaced by NAD83(NSRS2007) / KY1Z.

Method: Geocentric translations (geog2D domain)

Area of use: United States (USA) - Kentucky.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
