Aerial Photography <br />Johnson-Frank & Associates Inc. <br />(A8) Surveying & Mapping Services <br />City of Santa Ana <br />This task involves acquisition of imagery for the project. <br />• Upon receiving notification that all aerial targets have been set, Johnson-Frank will <br />mobilize a camera aircraft to the project site. Stereoscopic aerial photography (color or <br />B/W, as desired by the City) will be acquired using a Leica RC-30, Zeiss RMK-Top, or <br />Digital Vexcel UltraCamLp precision aerial mapping camera and fine-grain aerial <br />negative film, or possibly a digital aerial camera. <br />Photo Lab Work <br />This task involves processing of the aerial negative film, and production of derivative hard-copy <br />products. <br />• The aerial negatives will be processed, labeled, and checked for compliance with the <br />City-approved flight plan and industry standard flight tolerances. <br />• Contact prints will be printed using a LogETronics Mark II Automatic Dodging Printer, <br />and processed using an AGFA Model 125 Automatic Processor. <br />(This step will not occur if the digital camera is employed) <br />Film Scanning <br />This task involves scanning of the aerial negatives to produce raw digital raster imagery in <br />preparation for analytical aerotriangulation, photogrammetric data extraction and o?thorectification. <br />• Negatives of the aerial photography will be placed into a precision Photogrammetric <br />Scanning System and scanned at a resolution of 12.5 microns (2032 DPI). <br />e Automatic dodging software will optimize each image, evening out localized bright and <br />dark patches to ensure even, consistent looking imagery of the highest possible quality <br />for imaging tasks. <br />50 E.
