2006 Louisiana Laws - RS 50:3 — Plane coordinates

§3.  Plane coordinates

The plane coordinate values for a point on the earth's surface, used to express the geographic position or location of such point in the appropriate zone of this system, shall consist of two distances expressed in U.S. Survey feet and decimals of a foot when using the Louisiana Coordinate System of 1927 and expressed in meters and decimals of a meter, or the equivalent distance in feet and decimals of a foot, (conversion factor is 3937 divided by 1200), when using the Louisiana Coordinate System of 1983.  One of these distances to be known as the "x-coordinate", shall give the position in an east and west direction; the other, to be known as the "y-coordinate", shall give the position in a north and south direction.  These coordinates shall be made to depend upon and conform to plane rectangular coordinate values for the monumented points of the North American Horizontal Geodetic Control Network as published by the National Ocean Service/National Geodetic Survey, or its successors, and whose plane coordinates have been computed on the systems defined in this Chapter.  Any such station may be used for establishing a survey connection to either Louisiana Coordinate System.
