Common use of Aerial Photogrammetry Requirements Clause in Contracts

Aerial Photogrammetry Requirements. When base mapping for engineering is produced from aerial photogrammetry, any survey information will be provided to the Department in the specified formats previously mentioned. This includes all control points, traverses, baselines, or other information that is used in conjunction with producing the photogrammetric information. A detailed survey report shall also be submitted and approved by the NJDOT Geodetic Survey Office or appropriate Regional Survey Office. The approved Survey Report copies must be submitted to the Project Manager. This report shall document the ground control used, the method of determining GPS coordinates, and the data reduction/software processes used. The design files with this information will be separate from the actual mapping files. The mapping files themselves will be drawn to the standards of the particular discipline requesting the mapping. Standard Rules for Digitized Mapping: 1) No stream digitizing is allowed. 2) There will be no scale associated with elements in the design file (scale = 1:1). 3) There will be no rotation associated with views. 4) Contour lines and their corresponding elevations shall be placed in a design file separate from the rest of the topography. The contour lines and the elevation text are to be placed on different levels as per NJDOT CADD Standards. The contours and their elevations shall be drawn in a weight and size that meets the Department’s standards when the design file is plotted at 1:30 for English. 5) All existing baseline data and traverse information with ground ties shall each be placed in separate files. Stationing, bearings and curve data must be supplied for all baseline alignments. Monument information, if included, should also be in the traverse file. 6) The coordinate system for all supplied files shall be an exact overlay to allow direct attachment of any reference file without manipulation. 7) If a graphically depicted grid system is supplied, it must be placed on a unique level or in a separate file. 8) All existing topographic features shall be placed in a separate design file as per NJDOT CADD standards.
