Chapter 157 - OHIO COORDINATE SYSTEM
Section 157.06 - Ohio co-ordinate system definitions.
(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.
