4. Discovery Team
and Task Force

5. Wisconsin Society of Land Surveyors
• In mid-2018 the Wisconsin Society of Land Surveyors Board voted to create a
Task Force to explore the implications of NATRF2022.
• Will be organized under WSLS’s Geospatial Committee.
• Members will represent cross-section of Wisconsin geospatial community –
including private sector, software, hardware and utility companies – to help
prepare for the new reference system and its effects on the community.
• Bob Beilfuss, WSLS President, asked Howard Veregin, State Cartographer,
to serve as Chair of Task Force, and Richard Kleinmann, chair of Geospatial
Committee, to serve as Task Force co-Chair.
• WSLS financial sponsorship: Bob Beilfuss, President; Frank Thousand,
Executive Director; Terry Van Hout, President-Elect

6. Discovery Team Plan
Create a Discovery Team and hold a
meeting in the summer of 2018 to
identify (a) the main impacts of the
new reference system and (b) the
stakeholder groups most affected

• Name: “Policy and Procedures
Documents for the State Plane
Coordinate System of 2022”
• Notice of proposed change to the
State Plane Coordinate System;
request for comments
• Published 04/18/2018
• Document Citation: 83 FR 17149

15. FRN SUMMARY
https://www.federalregister.gov/documents/2018/04/18/2018-08141/
policy-and-procedures-documents-for-the-state-plane-coordinate-system-of-2022
• NGS will establish a State Plane
Coordinate System of 2022 (SPCS2022)
as part of the transition to the 2022
Terrestrial Reference Frames
• Like its predecessors, SPCS2022 will be
a nationwide system of conformal map
projections with defined accuracy
parameters (~100 parts per million)
providing access the National Spatial
Reference System.

16. FRN FEEDBACK
https://www.federalregister.gov/documents/2018/04/18/2018-08141/
policy-and-procedures-documents-for-the-state-plane-coordinate-system-of-2022
• NGS developed draft policy and
procedures defining the requirements
for SPCS2022.
• To ensure SPCS2022 meets customers’
needs, NGS invited written comments
on the draft SPCS2022 policy.
• Comments accepted until Friday,
August 31, 2018.
• These are PUBLIC comments

https://geodesy.noaa.gov/INFO/Policy/files/DRAFT_SPCS2022_Procedures.pdf

18. SPECIFIC CONCERNS OF NGS
1. Use of SPCS in organization?
2. Proposed SPCS2022 definitions: helpful or hardship?
3. Sufficient flexibility in SPCS2022 specs?
4. Acceptability of deadlines?
5. Special-purpose zones needed?

19. SPCS SPECIFICATIONS
• Lambert Conformal Conic, Transverse
Mercator, and Oblique Mercator
• GRS 80 ellipsoid
• To compute SPCS2022 coordinates, input
latitude and longitude must be from
NATRF2022
• Maximum allowable linear distortion for
designing a zone evaluated at topographic
surface, not at reference ellipsoid surface
(interesting, but no time to discuss) …
• And so on…

20. LAYERED ZONES
• A state can only have one or
two zone layers, as follows:
a. A single zone covering the
entire state;
b. Two or more sub-zones
• In states where this is
already in place (e.g.,
Kentucky), coordinates for
both zones are published in
NGS data sheets

21. LOW DISTORTION PROJECTIONS
NGS will design SPCS2022 zones only when linear distortion
design criterion is  ±50 ppm
Stakeholders who want
“low-distortion” SPCS2022
zones must design them as
contributing partners
Any such designs must
conform to all NGS
requirements and must be
approved by NGS for
incorporation in SPCS2022
Current WISCRS Grid-to-Ground Ratios range
from 16 ppm to 2 ppm (in SE Wisconsin) …
WISCRS distortion is much lower than 50 ppm

22. FEEDBACK MECHANISMS
• NGS requires “consensus” stakeholder input to act on proposals for SPCS2022
• Proposals must be co-signed by stakeholders
• NGS will only act on unanimous agreement
• NGS will not act on input from individuals
• Requests for zones (designed by NGS) or proposals for zones (designed by contributing
partners) must be received by NGS by December 31, 2019
• For NGS-approved proposed designs by contributing partners, final defining parameters
must be received by NGS by December 31, 2020
• Confirmation of final design characteristics and computations will be provided by NGS to
stakeholders and contributing partners by December 31, 2021

23. STAKEHOLDERS & PARTNERS
• Stakeholders: NGS customers and users of SPCS within a state most
involved in use, collection, and distribution of spatial data...Stakeholders
consist of one or more of the following organizations:
a. State departments of transportation.
b. State GIS or cartographer offices
c. State professional surveying and engineering societies
d. State GIS or other professional geospatial organizations
e. Universities or other post-secondary educational institutions
f. Other departments, offices, and organizations within a state with similar roles
• Contributing partners are: Organizations or individuals identified by NGS
stakeholders to design SPCS2022 zones on behalf of stakeholders and in
cooperation with NGS. A contributing partner can also be a stakeholder.

24. Questions?

25. Discovery Team
Response to
NGS FRN

26. DISCOVERY TEAM RESPONSE
Our Primary Concern: Include WISCRS data in NGS
software, databases and publications
• Did not specifically answer the 5 questions posed by NGS in FRN, as these
were related to SPCS design parameters and SPCS use
• “Ignored” the stipulation that a state could only have two zones layers …
and asked for three!
• Accepted that NGS would not design LDPs, as we were concerned only that
NGS accept and use the existing LDP (WISCRS), not redesign it
• The latter also implied that WISCRS would not need to meet all NGS specs
for SPCS zones

27. RESPONSE RATIONALE (1)
Wisconsin has relied upon low-distortion projection
(LDP) systems for decades. County coordinate systems
were first used in the state in the 1970s, with the first
systematic statewide system (Wisconsin County
Coordinate System, or WCCS) being developed in 1995.
WCCS evolved into the current system, WISCRS
(Wisconsin Coordinate Reference Systems) in 2006.

28. RESPONSE RATIONALE (2)
Wisconsin’s county systems were originally developed,
and continue to be maintained, in direct response to
user needs for local coordinate systems that minimize
differences between measured ground distances and
projected grid distances while maintaining a
mathematical linkage to national datums like NAD 83.

29. RESPONSE RATIONALE (3)
Therefore, the Wisconsin community will be best served by a three-
tiered coordinate system structure:
• The coordinate system WISCRS;
• A three-zone State Plane Coordinate System modeled on the
current SPCS zones for the state;
• A single zone for the entire state, possibly based on WTM.
Request that NGS recognize WISCRS as a component of this three-
tiered system, provide WISCRS coordinates on NGS data sheets and
within NGS databases, and incorporate WISCRS within NGS
coordinate transformation software.
Not asking for NGS support to develop an LDP.

30. RESPONSE RATIONALE (4)
Request reflects prevalence of WISCRS within the
state’s land information communities, large
investments made in WISCRS spatial networks,
extensive use of WISCRS in infrastructure design and
construction, and incorporation of WISCRS into major
commercial software tools … these examples show the
significant financial interest in maintaining WISCRS
and the buy-in it has received from the private sector.
