national standards.**

Be it enacted by the Legislature of the State of South Dakota:

**Section 1.
That § 43-22-1 be AMENDED:**

**43-22-1.
**~~The
systems of plane coordinates which have been established by the~~
~~United
States Department of Commerce, National Oceanic and Atmospheric
Administration,~~__The
most recent system of plane coordinates established by the National
Geodetic Survey__
for defining and stating the geographic positions or locations of
points on__,

**Section ****4.
That § 43-22-6 be AMENDED:**

**43-22-6.
**~~For
purposes of more precisely defining the South Dakota coordinate
systems of 1927 and 1983, the following definition by the United
States Department of Commerce, National Oceanic~~
~~and
Atmospheric Administration, is adopted:~~

~~(1) The
South Dakota coordinate system of 1927, north zone, is a Lambert
conformal projection of the Clarke Spheroid of 1866, having standard
parallels at north latitudes 44 degrees 25 minutes and 45 degrees 41
minutes, along which parallels the scale shall be exact. The origin
of coordinates is at the intersection of the meridian 100 degrees 00
minutes west of Greenwich and the parallel of 43 degrees 50 minutes
north latitude. This origin is given the coordinates: x equals
2,000,000 feet and y equals 0 feet.~~

~~(2) The
South Dakota coordinate system of 1927, south zone, is a Lambert
conformal projection of the Clarke Spheroid of 1866, having standard
parallels at north latitudes 42 degrees 50 minutes and 44 degrees 24
minutes, along which parallels the scale shall be exact. The origin
of coordinates is at the intersection of the meridian 100 degrees 20
minutes west of Greenwich and the parallel 42 degrees 20 minutes
north latitude. This origin is given the coordinates: x equals
2,000,000 feet and y equals 0 feet.~~

~~(3) The
South Dakota coordinate system of 1983, north zone, is a Lambert
conformal conic projection of the North American Datum of 1983,
having standard parallels at north latitudes 44 degrees 25 minutes
and 45 degrees 41 minutes along which parallels the scale shall be
exact. The origin of coordinates is at the intersection of the
meridian 100 degrees 00 minutes west of Greenwich and the parallel 43
degrees 50 minutes north latitude. This origin is given the
coordinates: x equals 600,000 meters and y equals 0 meters.~~

~~(4) The
South Dakota coordinate system of 1983, south zone is a Lambert
conformal conic projection of the North American Datum of 1983,
having standard parallels at north latitudes 42 degrees 50 minutes
and 44 degrees 24 minutes along which parallels the scale shall be
exact. The origin of coordinates is at the intersection of the
meridian 100 degrees 20 minutes west of Greenwich and the parallel 42
degrees 20 minutes north latitude. This origin is given the
coordinates: x equals 600,000 meters and y equals 0 meters.~~__The
official geodetic datums that geodetic coordinates, including
latitude, longitude, ellipsoid height, orthometric height, or dynamic
height, are referenced within this state, shall be defined for the
National Spatial Reference System or its successor.__

**Section ****5.
That § 43-22-8 be AMENDED:**

**43-22-8.
**The plane
coordinate values ~~for
~~__of
__a point on the
earth's surface, __to
be __used to
express the geographic position or location of such point in the
appropriate zone of~~
these systems,~~__
the South Dakota state plane coordinate system,__~~
shall~~
consist of two distances, expressed in ~~United
States survey ~~feet
and decimals of a foot~~
when using the South Dakota coordinate system of 1927 and expressed
in United States survey feet and decimals of a foot when using the
South Dakota coordinate system of 1983~~__
or meters and decimals of a meter__.
~~One
of these distances, to be known as the "x‑coordinate"
on North American Datum 1927 and "Easting" on North
American Datum 1983, shall give the position in an east‑and‑west
direction; the other, to be known as the "y‑coordinate"
on North American Datum 1927 and "Northing" on North
American Datum 1983, shall give the position in a north‑and‑south
direction. These coordinates shall be made to depend upon and conform
to plane rectangular coordinate values for the monumented points of
the North American Horizontal Geodetic Control Network as published
by the United States Department of Commerce, National Oceanic and
Atmospheric Administration, and whose plane coordinates have been
computed on the systems defined in this chapter. Any such station may
be used for establishing a survey connection to either South Dakota
coordinate system.~~__
If the values are expressed in feet, a definition of one foot equals
0.3048 meter exactly is used as the standard foot for the South
Dakota state plane coordinate system. One of the two distances, to be
known as the east or x-coordinate, gives the distance east of the
y-axis; the other, to be known as the north or y-coordinate, gives
the distance north of the x-axis. The y-axis of any zone is parallel
with the central meridian of that zone. The x-axis of any zone is at
the right angles to the central meridian of that zone. Height is the
coordinate value of the vertical elements of the National Spatial
Reference System expressed as feet or meters and identified as
ellipsoid height or orthometric height.__

**Section ****6.
That § 43-22-9 be AMENDED:**

**43-22-9.
**~~No
coordinates based on either South Dakota coordinate system,
purporting to define the position of a point on a land boundary,
shall be presented ~~~~to
be recorded in any public land records or deed records unless such
point is within one kilometer of a monumented horizontal control
station established in conformity with the standards of accuracy and
specification for first or second‑order geodetic surveying as
prepared and published by the federal geodetic control committee of
the United States Department of Commerce. Standards and
specifications of the federal geodetic control committee in force on
date of the survey apply. Publishing existing control stations, or
the acceptance with intent to publish the newly established stations,
by the United States Department of Commerce, National Oceanic and
Atmospheric Administration, shall constitute evidence of adherence to
the federal geodetic control committee specifications. Above
limitations may be modified by a duly authorized state agency to meet
local conditions~~__No
coordinates based on the South Dakota state plane coordinate system
purporting to define the position of a point on a land boundary may
be presented to be recorded in any plat, easement, exhibit, deed,
certified corner records, or other document unless the coordinate or
coordinates are accompanied by a description of the horizontal datum,
realization, and methodology used and published within the same
document.__

**Section ****7.
That § 43-22-10 be AMENDED:**

**43-22-10.
**~~The
use of the term "South Dakota coordinate system of 1927 north
zone," or "South Dakota coordinate system of 1927 south
zone," or the use of the term "South Dakota coordinate
system of 1983 north zone," or "South Dakota coordinate
system of 1983 south zone," on any map, report of survey, or
other document, shall be limited to coordinates based on the South
Dakota coordinate systems as defined in this chapter~~__The
use of the term, South Dakota state plane coordinate system, on any
map, report of survey, or other documents, is limited to coordinates
based on the South Dakota state plane coordinate system as defined in
this chapter__.

**Section ****8.
That § 43-22-11 be AMENDED:**

**43-22-11.
**If any tract of
land to be defined by a single description extends from one
__coordinate
zone __into ~~the
other ~~__another
__~~of
the ~~coordinate~~
zones described by §§ 43-22-3 and 43-22-4~~__
zone__, the
positions of all points on its boundaries may be referred to ~~either
~~__by__~~of
the two zones,~~
the zone ~~which
~~__that
__is used being
specifically named in the description.

**Section ****9.
That § 43-22-12.1 be AMENDED:**

**43-22-12.1.
**For purposes of
describing the location of any survey station or land boundary corner
in the state, it~~
shall be considered~~__
is__ a complete,
legal, and satisfactory description of~~
such ~~__
the __location to
give the position of the survey station or land boundary corner on
the system of plane coordinates defined in this chapter.__
Whenever coordinates based on the South Dakota state plane coordinate
system are used to describe any tract of land that in the same
document is also described by reference to any subdivision, line, or
corner of the United States Public Lands Survey, the description by
coordinates must be construed as supplemental to the basic
description of the subdivision, line, or corner contained in the
official plats and field notes filed of record, and in the event of
any conflict, the description by reference to the subdivision, line,
or corner of the United States Public Lands Survey prevails over the
description by coordinates.__

**Section ****10.
That § 43-22-13 be AMENDED:**

**43-22-13.
**Nothing contained
in this chapter requires a purchaser, mortgagee, or insurer of real
property to rely wholly on a land description, any part of which
depends exclusively ~~on
either South Dakota coordinate system~~__
upon the South Dakota state plane coordinate system__.

**Section ****11.
That chapter 43-22 be amended with a NEW SECTION:**

__The
provisions of this chapter may not be construed to prohibit the
appropriate use of other geodetic reference networks.__
