Ohio Revised Code
Chapter 157 | Ohio Co-Ordinate System
Section 157.06 | Ohio Co-Ordinate System Definitions.

Effective: October 1, 1985
Latest Legislation: House Bill 134 - 116th General Assembly
(A) As defined by the United States department of commerce:
(1) The "Ohio co-ordinate system of 1927, north zone" is a Lambert conformal conic projection of the Clarke spheroid of 1866, having standard parallels at north latitudes of 40° 26' and 41° 42' along which parallels the scale shall be exact; the origin of co-ordinates is at the intersection of the meridian 82° 30' west of Greenwich and the parallel 39° 40' north latitude. This origin is given the co-ordinates: x = 2,000,000 feet and y = 0 feet.
(2) The "Ohio co-ordinate system of 1927, south zone" is a Lambert conformal conic projection of the Clarke spheroid of 1866, having standard parallels at north latitudes 38° 44' and 40° 02' along which parallels the scale shall be exact. The origin of co-ordinates is at the intersection of the meridian 82° 30' west of Greenwich and the parallel 38° 00' north latitude. This origin is given the co-ordinates: x = 2,000,000 feet and y = 0 feet.
(B) As defined by the United States department of commerce:
(1) The "Ohio co-ordinate system of 1983, north zone" is a Lambert conformal conic projection of the North American datum of 1983, having standard parallels at north latitudes 40° 26' and 41° 42' along which parallels the scale shall be exact. The origin of co-ordinates is at the intersection of the meridian 82° 30' west of Greenwich and the parallel 39° 40' north latitude. This origin is given the co-ordinates: x = 600,000 metres and y = 0 metres.
(2) The "Ohio co-ordinate system of 1983, south zone" is a Lambert conformal conic projection of the North American datum of 1983, having standard parallels at north latitudes 38° 44' and 40° 02', along which parallels the scale shall be exact. The origin of co-ordinates is at the intersection of the meridian 82° 30' west of Greenwich and the parallel 38° 00' north latitude. This origin is given the co-ordinates: x = 600,000 metres and y = 0 metres.
