Chapter NR 129

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.

NR 129.13(4) (4) Map accuracy.

NR 129.13(4)(a) (a) Contours.

NR 129.13(4)(a)1. 1. Ninety percent of the elevations determined from the solid-line contours of the topographic maps shall have an accuracy with respect to true elevation of 1/2 contour interval or better, and no such elevations shall be in error by more than one contour interval.

NR 129.13(4)(a)2. 2. In each particular area where the intermediate contours have been omitted due to the steepness of the ground slopes, and only the index contours are delineated on the maps, the accuracy stipulations apply to the contour interval of the index contours.

NR 129.13(4)(a)3. 3. In densely wooded areas where heavy brush or tree cover fully obscures the ground and the contours are shown as dashed lines, the contours shall be plotted as accurately as possible from the stereoscopic model, while making full use of spot elevations obtained during ground control surveys and all spot elevations measured photogrammetrically in places where the ground is visible.

NR 129.13(4)(b) (b) Spot elevations. Ninety percent of all photogrammetrically determined spot elevations shall have an accuracy with respect to true elevation of 1/4 contour interval or better, and no such elevations shall be in error by more than 1/2 contour interval.

NR 129.13(4)(d) (d) Horizontal control. Each horizontal control station and section corner shall be plotted on the finished map sheets within 1/100 of an inch of its true position as expressed by the adjusted coordinates computed for the point.

NR 129.13(4)(e) (e) Planimetric features.

NR 129.13(4)(e)1. 1. Ninety percent of all well-defined planimetric features on the photographs shall be plotted so that their position on the finished maps shall be accurate to within 1/40 of an inch of their true coordinate position and no point shall be misplaced on the finished map by more than 1/20 of an inch from its true position.

NR 129.13(5) (5) Topographic maps.

NR 129.13(5)(a) (a) Coordinate grid. Grid line intersections of the state plane coordinate system shall be shown on the finished map(s) together with corresponding coordinate values. Spacing of these lines shall be 5 inches.

NR 129.13(5)(b) (b) Match lines. Match lines shall be provided for the map sheets so that each sheet may be joined accurately to those adjacent to it.

NR 129.13(5)(c) (c) Planimetry.

NR 129.13(5)(c)1. 1. The map(s) shall contain all planimetric features which are visible from the aerial photography, including land use features such as, but not limited to, buildings, canals, ditches, reservoirs, trails, roads, highways, railroads, ferry slips, fords, quarries, borrow pits, cemeteries, orchards, boundaries of wooded areas, fence lines and individual, lone, large trees that can be recognized as such. Structures, such as bridges, trestles, tunnels, piers, retaining walls, dams, power plants, transformer and other substations, transportation terminals and airfields, storage tank fields, and the like, shall also be shown.

NR 129.13(5)(c)2. 2. Buildings and similar dimensionable objects shall be correctly outlined and oriented on the maps, and shall be to actual scale, except those building dimensions smaller than representable by 1/20 inch in size. Minor irregularities in building outlines that are not representable by 1/40 inch at map scale shall be ignored.

NR 129.13(5)(c)3. 3. Township, range, and section lines; and city, town, county, and political subdivision lines shall be obtained by the consultant from the municipality or other available sources and identified on the map(s).

NR 129.13(5)(d) (d) Spot elevation.

NR 129.13(5)(d)1. 1. Spot elevations determined photogrammetrically or by field survey shall be shown on the maps in proper position at water level on the shoreline of lakes, reservoirs, ponds and the like; on hilltops; in saddles; at the bottom of depressions; at the intersection of well-traveled roads, principal streets in cities, railroads, and highways; and on the centerline at each end of bridges and like locations where such elevations are significant.

NR 129.13(5)(d)2. 2. In areas where the contours are more than 3 inches apart at map scale, photogrammetric spot elevations shall also be shown to adequately depict the ground configuration.

NR 129.13(5)(e) (e) Topography.

NR 129.13(5)(e)1. 1. Unless otherwise stipulated in special provisions, the maps shall contain all representable and specified topographic features which are visible from the aerial photography.

NR 129.13(5)(e)2. 2. Contours shall be delineated to represent true elevation above mean sea level and the exact shape of the ground. Every fifth contour shall be accentuated and numbered.

NR 129.13(5)(e)3. 3. Wherever they exist, hydrographic features required on the maps shall include all watercourses which are longer than one inch at map scale, and all ponds, lakes, flowages and wetlands.

NR 129.13(5)(e)4. 4. Floodplain, floodway and shoreland limits shall be shown on the finished map sheets along with other pertinent information related to the mapping project.
