Current through Register Vol. 51, No. 1, July 1, 2024
RELATES TO:
				KRS
				1.020,
				42.630,
				42.650,
				42.740
NECESSITY, FUNCTION, AND CONFORMITY:
				KRS
				42.650(5) authorizes the
				Division of Geographic Information Systems within the Commonwealth Office of
				Technology (COT) to promulgate administrative regulations to implement that
				statute. KRS
				1.020(2) requires the
				Commonwealth Office of Technology (COT) to establish and publish a series of
				layered zones covered by geodetically referenced mapping projections adopted
				and supported by the National Geodetic Survey (NGS) as a component of the
				National Spatial Reference System (NSRS).
Section
			 1. Definitions.
(1) "COT" means
			 Commonwealth Office of Technology.
(2) "Customary foot" means the foot as a
			 linear unit of measure in a generic sense outside the context of a specific
			 conversion regimen.
(3) "Geodetic
			 datum" means a geometric model representing the earth's size and shape. The
			 mathematical surface of a geodetic datum is an oblate spheroid, called a
			 reference ellipsoid, generally designed to best fit mean sea level either
			 globally or for a stated region. In the context of a geometric framework in
			 which horizontal coordinates are expressed in angular units as latitude and
			 longitude, a geodetic datum is also referred to as a terrestrial reference
			 frame, or simply, reference frame.
(4) "Geodetically referenced mapping
			 projection" means a planar surface mathematically associated with a geodetic
			 datum, or terrestrial reference frame, such that unique positions relative to
			 that datum or terrestrial reference frame can be converted to and from
			 commensurately unique positions on that plane.
(5) "GIAC" means Geographic Information
			 Advisory Council.
(6) "NGS" means
			 National Geodetic Survey.
(7)
			 "NOAA" means National Oceanic and Atmospheric Administration.
(8) "KSPCS" means Kentucky State Plane
			 Coordinate System and is the collection of all series applicable to the
			 Commonwealth of Kentucky.
(9)
			 "NSRS" means National Spatial Reference System.
(10) "SPCS" means State Plane Coordinate
			 System.
(11) "State plane layer"
			 means a collection of one (1) or more zones, all defined on a common geodetic
			 datum or terrestrial reference frame and designed to achieve, in aggregate, a
			 common theme based on similar performance characteristics that may cover the
			 Commonwealth in part or in whole.
(12) "State plane series" means a collection
			 of one (1) or more layers defined on a common and unique geodetic datum or
			 terrestrial reference frame representing a complete implementation of the
			 national State Plane Coordinate System (SPCS) for the Commonwealth on that
			 datum or terrestrial reference frame.
(13) "State plane zone", or "zone," is a
			 geographic region covered by a uniquely defined geodetically referenced mapping
			 projection and generally comprised of a collection of mutually adjacent whole
			 counties such that all included counties lie completely within a given zone. In
			 special cases a zone may partially cover a county or parts of mutually adjacent
			 counties to represent a geographic area of specific interest. A zone may cover
			 the Commonwealth either in part or in whole.
