Chapter 55. PLANE COORDINATE SYSTEM
§ 5503. Description of 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 2 distances, expressed in U.S. Survey Feet and expressed in meters and decimals of a meter when using the Delaware Coordinate System of 1983. When using the Delaware Coordinate System of 1927, 1 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. When using the Delaware Coordinate System of 1983, 1 of the distances, to be known as the “northing,” of “N,” shall give the position in a north-and-south direction; the other, to be known as the “easting” or “E,” shall give the position in an east-and-west directional. In both cases these coordinates shall be made to depend upon and conform to plane rectangular coordinate values for the monument points of the North American National Geodetic Horizontal Network as published by the National Ocean Service/National Geodetic survey (formerly the United States Coast and 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 Delaware Coordinate System. The unit used to convert feet to meters shall be the United States survey foot, which is 39.37/12 feet for each meter.
