Designation of systems
    Sec. 1. The systems of plane coordinates that have beenestablished by the National Ocean Survey/National Geodetic Survey(formerly the United States Coast and Geodetic Survey) or itssuccessors for defining and stating the positions or locations ofpoints on the surface of the earth within Indiana are known anddesignated as the "Indiana coordinate system of 1927" and the"Indiana coordinate system of 1983".

Descriptions of systems; locating position of systems
    Sec. 3. (a) To more precisely describe the Indiana coordinatesystem of 1927, the following descriptions by the National OceanSurvey/National Geodetic Survey are adopted:
        (1) The "Indiana coordinate system of 1927, east zone" is atransverse Mercator projection of the Clarke spheroid of 1866,having a central meridian 85 degrees 40 minutes west ofGreenwich, on which meridian the scale is set at one part in30,000 too small. The origin of coordinates is at the intersectionof the meridian 85 degrees 40 minutes west of Greenwich andthe parallel 37 degrees 30 minutes north latitude. This origin isgiven the coordinates: x = 500,000 feet and y = 0 feet.
        (2) The "Indiana coordinate system of 1927, west zone" is atransverse Mercator projection of the Clarke spheroid of 1866,having a central meridian 87 degrees 05 minutes west ofGreenwich, on which meridian the scale is set at one part in30,000 too small. The origin of coordinates is at the intersectionof the meridian 87 degrees 05 minutes west of Greenwich andthe parallel 37 degrees 30 minutes north latitude. This origin isgiven the coordinates: x = 500,000 feet and y = 0 feet.
    (b) To more precisely describe the Indiana coordinate system of1983, the following description by the National OceanSurvey/National Geodetic Survey is adopted:
        (1) The "Indiana coordinate system of 1983, east zone" is atransverse Mercator projection of the North American Datumof 1983, having a central meridian 85 degrees 40 minutes westof Greenwich, on which meridian the scale is set at one part in

30,000 too small. The origin of coordinates is at the intersectionof the meridian 85 degrees 40 minutes west of Greenwich andthe parallel 37 degrees 30 minutes north latitude. This origin isgiven the coordinates: x = 100,000 meters and y = 250,000meters.
        (2) The "Indiana coordinate system of 1983, west zone" is atransverse Mercator projection of the North American Datumof 1983, having a central meridian 87 degrees 05 minutes westof Greenwich, on which meridian the scale is set at one part in30,000 too small. The origin of coordinates is at the intersectionof the meridian 87 degrees 05 minutes west of Greenwich andthe parallel 37 degrees 30 minutes north latitude. This origin isgiven the coordinates: x = 900,000 meters and y = 250,000meters.
    (c) To locate the position of the coordinate systems on the surfaceof the earth in Indiana, the following shall be used:
        (1) The position of the Indiana coordinate system of 1927 shallbe determined from horizontal geodetic control pointsestablished throughout Indiana in conformity with the standardsof accuracy and specifications for first-order and second-ordergeodetic surveying as prepared and published by the FederalGeodetic Control Committee (FGCC) of the United StatesDepartment of Commerce, whose geodetic positions have beenrigidly adjusted on the North American Datum of 1927, andwhose coordinates have been computed on the Indianacoordinate system of 1927. Standards and specifications of theFGCC (or its successors) in force on the date of the surveyapply.
        (2) The position of the Indiana coordinate system 1983 shall bedetermined from horizontal geodetic control points establishedthroughout Indiana in conformity with the standards of accuracyand specifications for first-order and second-order geodeticsurveying as prepared and published by the Federal GeodeticControl Committee (FGCC) of the United States Department ofCommerce, whose geodetic positions have been rigidly adjustedon the North American Datum of 1983, and whose coordinateshave been computed on the Indiana coordinate system of 1983.Standards and specifications of the FGCC (or its successors) inforce on the date of the survey apply.

Naming and designation of system in land descriptions
    Sec. 4. (a) As established for use in the east zone, the Indianacoordinate system of 1927 or the Indiana coordinate system of 1983:
        (1) shall be named; and
        (2) in any land description in which it is used, shall bedesignated the:
            (A) "Indiana coordinate system of 1927, east zone"; or
            (B) "Indiana coordinate system of 1983, east zone".    (b) As established for use in the west zone, the Indiana coordinatesystem of 1927 or the Indiana coordinate system of 1983:
        (1) shall be named; and
        (2) in any land description in which it is used. shall bedesignated, the:
            (A) "Indiana coordinate system of 1927, west zone"; or
            (B) "Indiana coordinate system of 1983, west zone".

IC 32-19-1-5
Tract located in both zones
    Sec. 5. If a tract of land to be defined by a single descriptionextends from one (1) into the other of the east zone or the west zone:
        (1) the positions of all points on the boundaries of the tract maybe referred to as either the east zone or the west zone; and
        (2) the zone that is used must be specifically named in thedescription.

IC 32-19-1-6
Use of terms; limits on use of system
    Sec. 6. (a) The use of the term "Indiana coordinate system of1927" or "Indiana coordinate system of 1983" on any map, report ofsurvey, or other document shall be limited to coordinates based onthe Indiana coordinate system described in this chapter.
    (b) Beginning January 1, 1990, the Indiana coordinate system of1927 may not be used, and only the Indiana coordinate system of1983 may be used.
