NR 129.13(1)(a)(a) Contracts between the grantee and the mapping consultant, and between the mapping consultant and subcontractors, if any, shall conform to the minimum mapping specifications set forth in this section, unless par. (b) is applicable. NR 129.13 NoteNote: Within the 7 southeastern Wisconsin counties of Kenosha, Milwaukee, Ozaukee, Racine, Walworth, Washington and Waukesha, the department encourages applicants to conduct mapping projects in accordance with specifications for large scale mapping which have been prepared by the Southeastern Wisconsin Regional Planning Commission (SEWRPC). These specifications may be obtained by writing to the:
NR 129.13 Note Southeastern Wisconsin Regional Planning Commission
916 N. East Avenue
P.O. Box 769
Waukesha, WI 53187 - 1607
NR 129.13(1)(b)(b) If the department determines that compliance with the specifications of this section would be impractical in specific cases, it may approve alternative specifications which, in its opinion, represent a reasonable approach to achieving the desired end product. NR 129.13(1)(c)(c) The maps, aerial photographs and negatives, and all other data developed as part of the mapping project shall be considered public records and shall be made available for public inspection. NR 129.13(2)(a)(a) Records. It shall be the grantee’s responsibility to make known to the mapping consultant all existing monumentation and to furnish the consultant with existing local unpublished survey data of the required order of accuracy or better. NR 129.13(2)(b)(b) Control report. The consultant shall prepare and furnish to the grantee a bound control report providing all data pertaining to the project survey control. The report shall contain: NR 129.13(2)(b)1.1. A narrative, outlining survey methods used and applicable survey instrumentation and computational and adjustment procedures utilized; NR 129.13(2)(b)2.2. The closure and adjustment computations and original field note books for horizontal and vertical control; NR 129.13(2)(b)3.3. Sketches, descriptions, elevations and state plane coordinates of all existing and newly established recoverable control; and NR 129.13(2)(b)4.4. A scale control diagram summarizing the existing project survey control utilized for origin and closure purposes, along with the relationship to newly established recoverable horizontal and vertical control. NR 129.13(2)(c)(c) Vertical control. The consultant shall perform necessary field surveys to maintain full model vertical ground control with all elevations referred to national geodetic vertical datum of 1929. Third-order accuracy is required and shall conform to national geodetic survey specifications. There shall be enough ground-surveyed bench marks such that no point within the flood plain or shoreland area will be greater than 3000 feet from a described and recoverable bench mark. No analytical aerotriangulation for vertical mapping control shall be accepted unless it is otherwise impractical to gain physical or legal access. NR 129.13(2)(d)(d) Horizontal control. The consultant shall perform horizontal control surveys to obtain third-order, class I accuracy and shall conform to national geodetic survey specifications. The horizontal control survey shall be based on the state plane coordinate system and shall originate and end on the basic control for which closures are known and available, or shall be run to make a closed and checked circuit. Analytical aerotriangulation for horizontal mapping control is acceptable. NR 129.13(2)(e)(e) Specifications for vertical and horizontal control have been prepared and published by the U.S. department of commerce in the following publications: NR 129.13(2)(e)1.1. “Classifications, Standards of Accuracy, and General Specifications of Geodetic Control Surveys” reprinted January 1979; NTIS accession no. PB265442. NR 129.13(2)(e)2.2. “Specifications to Support Classification, Standards of Accuracy, and General Specifications of Geodetic Control Surveys” reprinted January 1979; NTIS accession no. PB261037. NR 129.13 NoteNote: These publications may be obtained from either the:
NR 129.13 Note National Geodetic Information Center (single copies)
C185, NOS
Rockville, MD 20852
or the:
U.S. Department of Commerce (multiple copies)

NR 129.13 NoteNote: Both publications are available for inspection at the offices of the department, the secretary of the state, and the legislative reference bureau.
NR 129.13(3)(a)(a) Camera. Photography shall be exposed with a 6-inch focal length lens to produce negatives 9¿9 inches in size. The camera used and its designated companion film magazine must have been certified by the U.S. geological survey or the manufacturer within 3 years prior to the date of the grant application. NR 129.13(3)(b)(b) Scale. Photography shall be obtained from a flight height chosen by the mapping consultant so that the specified contour interval accuracy is assured. However, flight height greater than 4800 feet above mean floodplain elevation is unacceptable for use with an optical-mechanical stereoplotter, and flight height greater than 3000 feet above mean floodplain elevation is unacceptable with a projection type stereoplotter. Negatives which have a departure from the intended scale of photography exceeding 5% may be rejected. NR 129.13(3)(c)(c) Overlap. Overlap shall be sufficient to provide full stereoscopic coverage of the complete area to be mapped. The endlap shall average 60%, with side lap not less than 20% or more than 55%. NR 129.13(3)(d)(d) Tilt. Tilt of any negative by more than 3°, an average tilt of more than one degree for the entire project, or tilt between any 2 successive negatives exceeding 4° may be cause for rejection. NR 129.13(3)(e)(e) Crab. Crab in excess of 3° may be cause for rejection of the flight line of negatives or portions thereof in which such crab occurs. NR 129.13(3)(f)(f) Quality. Photography shall be clear and sharp in detail and of average uniform density. It shall also be free of clouds, cloud shadows, light streaks, static marks or other blemishes which would interfere with its intended use. All photography shall be taken when the area to be mapped is free of snow, with the water confined to the main low water channel, before foliation, and at such time as to insure a minimum solar angle of 30°. NR 129.13(3)(g)(g) Contact prints. Contact prints from the vertical negatives shall be printed on double weight, semi-matte paper of suitable contrast. NR 129.13(3)(h)(h) Photo index. Photo indices shall be prepared by directly photographing on safety base film, at a convenient scale, the assembly of contact prints from all indexed and evaluated prints and shall be reproduced on dimensionally stable polyester base material. The photo index map shall carry a suitable title, scale, and north point.
