UTAH COORDINATE SYSTEM AMENDMENTS
2 2001 GENERAL SESSION
3 STATE OF UTAH
4 Sponsor: Parley Hellewell
5 This act modifies the Utah Coordinate System. The act adopts special publications to more
6 precisely define the Utah Coordinate Systems of 1927 and 1983. The act modifies the
7 requirements for any document identifying or using a coordinate system. The act establishes
8 that, in addition to the Utah Coordinate System of 1983, any person, corporation,
9 municipality, county, or state agency establishing a new coordinate network must conform
10 to the current federal coordinate update.
11 This act affects sections of Utah Code Annotated 1953 as follows:

21 57-10-6. Utah Coordinate Systems of 1927 and 1983 defined.
22 [(1)] For purposes of more precisely defining the Utah Coordinate [System of 1927]
23 Systems, the following [definition by the United States Coast and Geodetic Survey (not National
24 Ocean Service/National Geodetic Survey) is] special publications are adopted:
25 (1) For the Utah Coordinate System of 1927, the manual entitled "The State Coordinate
26 Systems (A Manual for Surveyors)," Special Publication No. 235, and "Plane Coordinate
27 Projection Tables for Utah," Special Publication No. 277. Both manuals are published by the U.S.

28 Department of Commerce, Coast and Geodetic Survey, and provide, in part, the following:

30 Projection of the Clarke Spheroid of 1866 having standard parallels at north latitudes 41 degrees
31 47 minutes and 40 degrees 43 minutes, along which parallels the scale shall be exact.
32 (ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes
33 west of Greenwich and the parallel 40 degrees 20 minutes north latitude.
34 (iii) This origin is given the coordinates: x=2,000,000 feet and y=0 feet.
35 (b) (i) The "Utah Coordinate System of 1927 Central Zone" is a Lambert Conformal Conic
36 Projection of the Clarke Spheroid of 1866 having standard parallels at north latitudes 40 degrees
37 39 minutes and 39 degrees 01 minutes, along which parallels the scale shall be exact.
38 (ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes
39 west of Greenwich and the parallel 38 degrees 20 minutes north latitude.
40 (iii) This origin is given the coordinates: x=2,000,000 feet and y=0 feet.
41 (c) (i) The "Utah Coordinate System of 1927 South Zone" is a Lambert Conformal Conic
42 Projection of the Clarke Spheroid of 1866 having standard parallels at north latitudes 38 degrees
43 21 minutes and 37 degrees 13 minutes, along which parallels the scale shall be exact.
44 (ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes
45 west of Greenwich and the parallel 36 degrees 40 minutes north latitude.
46 (iii) This origin is given the coordinates: x=2,000,000 feet and y=0 feet.
47 (2) For [purposes of more precisely defining] the Utah Coordinate System of 1983, the
48 manual entitled "State Plan Coordinate System of 1983," NOAA Manual NOS NGS 5. The
49 manual is published by the U.S. Department of Commerce, National Oceanic and Atmospheric
50 Administration, and provides, in part, the following [definition by the National Ocean
51 Service/National Geodetic Survey is adopted]:
52 (a) (i) The "Utah Coordinate System of 1983 North Zone" is a Lambert Conformal Conic
53 Projection of the North American Datum of 1983 having standard parallels at north latitudes 41
54 degrees 47 minutes and 40 degrees 43 minutes, along which parallels the scale shall be exact.
55 (ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes
56 west of Greenwich and the parallel 40 degrees 20 minutes north latitude.
57 (iii) This origin is given the coordinates: x or E=500,000 meters and y or N=1,000,000
58 meters.

59 (b) (i) The "Utah Coordinate System of 1983 Central Zone" is a Lambert Conformal Conic
60 Projection of the North American Datum of 1983 having standard parallels at north latitudes 40
61 degrees 39 minutes and 39 degrees 01 minutes, along which parallels the scale shall be exact.
62 (ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes
63 west Greenwich and the parallel 38 degrees 20 minutes north latitude.

78 Zone" on any map, report of survey, or other document [is limited to] shall be used to reference
79 the system, the coordinates [based on the Utah coordinate system], and the unit of measure as
80 defined in [this chapter] Subsection 57-10-6 (1).
81 (b) The use of the term "Utah Coordinate System of 1983 (HARN 1994, or the current
82 federal coordinate update used as the basis of the system being used) (North, Central, South) Zone"
83 shall be used to reference the system, the coordinates, and the unit of measure as defined in
84 Subsection 57-10-6 (2).
85 (2) Anyone using a coordinate system similar to the Utah coordinate system, such as one
86 where a modified elevation datum is used, shall clearly include "modified" in the title of the
87 coordinate system.
88 (3) Any survey or map based on any such modified coordinate system shall show the title
89 of the coordinate system, including "modified" in the title and show the appropriate combined

90 adjustment factor relating the system to the Utah coordinate system.
91 Section 3. Section 57-10-9 is amended to read:
92 57-10-9. Use of coordinate system optional.
93 The use of the Utah coordinate system by any person, corporation, or governmental agency

97a county, or state agency h WHO IS NOT UTILIZING AN EXISTING COUNTY COORDINATE SYSTEM
97b AND IS h
98 establishing a new h COUNTYWIDE h coordinate network [utilizing the Utah coordinate system may
98a use only] for
99 surveying or mapping, or both, must conform to the Utah Coordinate System of 1983[. After
100 January 1, 1997, persons using a Utah coordinate system may use only the Utah Coordinate System
101 of 1983], along with the current federal coordinate update.
