the earth (ground) and the location of naturalor artificial objects thereon.(2) Planimetric mapping is defined as producing amap that presents the horizontal positions onlyfor the features represented; distinguishedfrom a topographic map by the omission ofrelief in measurable form.(3) Airborne and spaceborne surveys are definedas the use of photogrammetry, LIDAR,IFSAR, or other similar measurementtechnologies for obtaining reliable informationabout physical objects and the environment,including terrain surface, through the processof recording, measuring, and interpretingimages and patterns of electromagnetic radiantenergy and other phenomena. Minimumallowable photogrammetric productionprocedures and standards are herebyestablished for photogrammetric mapping anddigital data production.(b) Production procedures for topographic and planimetricmapping surveys shall be in accordance with the standardsestablished by Chapter 3 of the Federal Geographic DataCommittee (FGDC) Geospatial Positioning Accuracy Standardand applicable extensions and revisions. These standards areincorporated by reference including subsequent amendments andeditions. The material is available from the Board office at acost of five dollars ($5.00) per copy or from the FGDC.(c) Topographic or planimetric maps, orthophotos, and/or relatedelectronic data, unless clearly marked as "Preliminary Map,"shall meet contractually specified FGDC Standards forhorizontal and vertical accuracies (in the absence of specifiedstandards, the National Map Accuracy Standards apply) andshall be sealed, signed and dated by the licensee.(d) When the resulting product is a digital (electronic) data set,or a map or document consists of more than one sheet orotherwise cannot be signed and sealed, a project report shall becertified, signed and sealed. Such report shall be clearly marked"Preliminary" if applicable.(e) Ground control for topographic and planimetric mappingprojects shall be in North Carolina State Plane CoordinateSystem grid coordinates and distances when the project is tied toGrid. A minimum of one permanent project vertical controlpoint shall be shown.(f) The project map or report shall contain the applicablefollowing information:PROPOSED RULES(1) Date of original data acquisition;(2) Altitude of sensor and sensor focal length, asapplicable;(3) Date of document or data set compilation;(4) If hard copy product is produced, the mapsshall contain a north arrow, map legend, finaldocument scale, including bargraph, andcontour interval, as applicable;(5) Coordinate system for horizontal and verticaldenoting SI or English units (i.e., NAD83,assumed, or other coordinate system);(6) A list or note showing the control points usedfor the project. The minimum data shown foreach point shall include: physical attributes(i.e. iron rod, railroad spike, etc), latitude andlongitude (or X and Y Grid coordinates), andelevation, as applicable;(7) If other data is included, the source andaccuracy of those items must be clearlyindicated;(8) A statement of accuracy complying withcontractually specified FGDC standardsconsistent with Paragraph (c) of this Rule;(9) For topographic maps or data sets, contours inareas obscured by man-made or naturalfeatures shall be uniquely identified orenclosed by a polygon clearly identifying theobscured area. The accuracies of the contoursor of features in this obscured area shall benoted "No reliance is to be placed on theaccuracy of these contours;"(10) A vicinity map depicting the project locationshall appear on the first sheet of all hard copymaps or in the report accompanying digitalfiles;(11) Company name, address and phone number;and(12) The name of the client for whom the projectwas conducted.(g) Nothing in this Section shall be construed to negate orreplace the relative accuracy standards found in Rules .1601through .1608.(h) A certificate, substantially in the following form, shall beaffixed to all maps or reports:"I, ______________________, certify that this project was completed under my direct and responsible charge from an actual (insert asappropriate: grond, airborne, photogrammetric) survey made under my supervision; that this photogrammetric survey was performedto meet Federal Geographic Data Committee Standards as applicable; that the imagery and/or original data was obtained on_____(date)__________; that the photogrammetric survey was completed on ___(date)_______; that contours shown as [broken lines]may not meet the stated standard; and all coordinates are based on ______________.(i) Documents transmitted electronically shall have thecomputer-generated seal removed from the original file and acopy of the project report shall be signed, sealed and sent to theclient. The electronic data shall have the following inserted inlieu of the signature and date:"This document originally issued and sealed by (name of sealer),(license number), on (date of sealing). This electronic mediashall not be considered a certified document. See the projectreport for certificate and seal."Authority G.S. 89C-10; 89C-20.21 NCAC 56 .1607 GLOBAL POSITIONINGSYSTEM SURVEYS(a) General.
