§ 34-8-4 Technical definition of systems– Origin of coordinates. – (a) For purposes of more precisely defining the Rhode Island coordinate systemof 1927, the following definition by the national ocean survey/nationalgeodetic survey is adopted:
The Rhode Island coordinate system of 1927 is a transverseMercator projection of the Clarke spheroid of 1866, having a central meridian71° 30' west of Greenwich, on which meridian the scale is set at one partin one hundred sixty thousand (160,000) too small. The origin of coordinates isat the intersection of the meridian 71° 30' west of Greenwich and theparallel 41° 05' north latitude. This origin is given the coordinates: x =500,000 feet and y = 0 feet.
(b) For the purposes of more precisely defining the RhodeIsland coordinate system of 1983, the following definition by the nationalocean survey/national geodetic survey is adopted:
The Rhode Island coordinate system of 1983 is a transverseMercator projection of the North American datum of 1983 having a centralmeridian 71° 30' west of Greenwich, on which meridian the scale is set atone part in one hundred sixty thousand (160,000) too small. The origin ofcoordinates is at the intersection of the meridian 71° 30' west ofGreenwich and the parallel 41° 05' north latitude. This origin is given thecoordinates: x = 100,000 meters, and y = 100,000 meters, and y = 0 meters.
