Designation of systems
Sec. 1. The systems of plane coordinates that have been
established by the National Ocean Survey/National Geodetic Survey
(formerly the United States Coast and Geodetic Survey) or its
successors for defining and stating the positions or locations of
points on the surface of the earth within Indiana are known and
designated as the "Indiana coordinate system of 1927" and the
"Indiana coordinate system of 1983".
As added by P.L.2-2002, SEC.4.

IC 32-19-1-3
Descriptions of systems; locating position of systems
Sec. 3. (a) To more precisely describe the Indiana coordinate
system of 1927, the following descriptions by the National Ocean
Survey/National Geodetic Survey are adopted:
(1) The "Indiana coordinate system of 1927, east zone" is a
transverse Mercator projection of the Clarke spheroid of 1866,
having a central meridian 85 degrees 40 minutes west of
Greenwich, on which meridian the scale is set at one part in
30,000 too small. The origin of coordinates is at the intersection
of the meridian 85 degrees 40 minutes west of Greenwich and
the parallel 37 degrees 30 minutes north latitude. This origin is
given the coordinates: x = 500,000 feet and y = 0 feet.
(2) The "Indiana coordinate system of 1927, west zone" is a
transverse Mercator projection of the Clarke spheroid of 1866,
having a central meridian 87 degrees 05 minutes west of
Greenwich, on which meridian the scale is set at one part in
30,000 too small. The origin of coordinates is at the intersection
of the meridian 87 degrees 05 minutes west of Greenwich and
the parallel 37 degrees 30 minutes north latitude. This origin is
given the coordinates: x = 500,000 feet and y = 0 feet.
(b) To more precisely describe the Indiana coordinate system of
1983, the following description by the National Ocean
Survey/National Geodetic Survey is adopted:
(1) The "Indiana coordinate system of 1983, east zone" is a
transverse Mercator projection of the North American Datum
of 1983, having a central meridian 85 degrees 40 minutes west
of Greenwich, on which meridian the scale is set at one part in
30,000 too small. The origin of coordinates is at the intersection
of the meridian 85 degrees 40 minutes west of Greenwich and
the parallel 37 degrees 30 minutes north latitude. This origin is
given the coordinates: x = 100,000 meters and y = 250,000
meters.
(2) The "Indiana coordinate system of 1983, west zone" is a
transverse Mercator projection of the North American Datum
of 1983, having a central meridian 87 degrees 05 minutes west
of Greenwich, on which meridian the scale is set at one part in
30,000 too small. The origin of coordinates is at the intersection
of the meridian 87 degrees 05 minutes west of Greenwich and
the parallel 37 degrees 30 minutes north latitude. This origin is
given the coordinates: x = 900,000 meters and y = 250,000
meters.
(c) To locate the position of the coordinate systems on the surface
of the earth in Indiana, the following shall be used:
(1) The position of the Indiana coordinate system of 1927 shall
be determined from horizontal geodetic control points
established throughout Indiana in conformity with the standards
of accuracy and specifications for first-order and second-order
geodetic surveying as prepared and published by the Federal
Geodetic Control Committee (FGCC) of the United States
Department of Commerce, whose geodetic positions have been
rigidly adjusted on the North American Datum of 1927, and
whose coordinates have been computed on the Indiana
coordinate system of 1927. Standards and specifications of the
FGCC (or its successors) in force on the date of the survey
apply.
(2) The position of the Indiana coordinate system 1983 shall be
determined from horizontal geodetic control points established
throughout Indiana in conformity with the standards of accuracy
and specifications for first-order and second-order geodetic
surveying as prepared and published by the Federal Geodetic
Control Committee (FGCC) of the United States Department of
Commerce, whose geodetic positions have been rigidly adjusted
on the North American Datum of 1983, and whose coordinates
have been computed on the Indiana coordinate system of 1983.
Standards and specifications of the FGCC (or its successors) in
force 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 Indiana
coordinate 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 be
designated 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 coordinate
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 be
designated, the:
(A) "Indiana coordinate system of 1927, west zone"; or
(B) "Indiana coordinate system of 1983, west zone".
As added by P.L.2-2002, SEC.4.
IC 32-19-1-5
Tract located in both zones
Sec. 5. If a tract of land to be defined by a single description
extends 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 may
be referred to as either the east zone or the west zone; and
(2) the zone that is used must be specifically named in the
description.

IC 32-19-1-6
Use of terms; limits on use of system
Sec. 6. (a) The use of the term "Indiana coordinate system of
1927" or "Indiana coordinate system of 1983" on any map, report of
survey, or other document shall be limited to coordinates based on
the Indiana coordinate system described in this chapter.
(b) Beginning January 1, 1990, the Indiana coordinate system of
1927 may not be used, and only the Indiana coordinate system of
1983 may be used.
