Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Approximation derived from tfm code 6864 ignoring time-dependent parameters and assuming ITRF96(1997.0) and WGS 84, plus NAD83(CORS96) and NAD83(HARN), can be considered the same within the accuracy of the tfm. In USA only replaces tfm code 1900.

Attributes

Unit: US survey foot

Geodetic CRS: NAD83(HARN)

Datum: NAD83 (High Accuracy Reference Network)

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

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: 2016-07-13

Scope: State-wide spatial data management.

Remarks: State law defines system in US survey feet. See code 3090 for equivalent metric definition. Replaces NAD83 / KY1Z (ft) for applications with an accuracy of better than 3 feet. Replaced by NAD83(NSRS2007) / KY1Z(ft).

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

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