Digital Orthographic Photography ;O'i(Y;; Preamble THIS AGREEMENT entered into this 5..fJ, day of Ape ;\ , 2010 between THE SIDWELL COMPANY, St. Charles, illinois, hereinafter called "Sidwell," party of the first part, and THE CITY OF SALINA, KANSAS, a government entity, hereinafter called "the City," party of the second part, WITNESSETH: THAT WHEREAS, The Sidwell Company is in the business of providing Aerial Photography and Digital Orthophotography, and Photogrammetric Mapping Services for various governmental agencies in the United States; and WHEREAS, the City is desirous of having The Sidwell Company provide Aerial Photography, Digital Orthophotography, and Photogrammetric Mapping Services. NOW, THEREFORE, in consideration of the mutual agreements hereinafter made, the recitals of fact hereinabove set forth, and other good and valuable consideration, the receipt of which is hereby acknowledged, the parties agree as follows; The Sidwell Company will perform the services described in the scope of work that follows. :,:~~:;Ai)' All aerial photography will be obtained during the spring of 2010, when the sky is sufficiently clear, deciduous foliage is dormant and when the ground is not obscured by snow, haze, smoke, dust, cloud shadows or other ground cover. The lighting conditions will be such that the sun is more than 30 degrees above the horizon. All photography will conform to the minimum requirements of the American Society of Photogrammetry and Remote Sensing (ASPRS) and the USGS Standard Specifications for Aerial Photography for Photogrammetric Mapping. Aircraft and Crew Aircraft will be equipped with all essential GPS navigational and photographic instruments. Flight crew used on the project includes a commercial-licensed pilot and a camera operator, each with extensive experience in aerial photographic missions. The aircraft will be operated and maintained in accordance with the regulations of the Federal Aviation Administration and Civil Aeronautics Board. The airplane has been modified such that, when the camera is mounted with all its parts above the outer structure, an unobstructed view is obtained, shielded from exhaust gases, oil, effluence, and air turbulence. No window of glass or other material will be interposed between the camera and the ground to be photographed. Sidwell aircraft have a proven service ceiling with operating load of 20,000 feet above mean sea level. Airborne GPS The aircraft is equipped with an Ll/L2 dual frequency GPS antenna, Magellan Z-Max receiver, Airborne GPS, and CCNS-4 flight management system. Flight planning software will be used to define the mission and communicate with Sidwell's CCNS-4 Flight Management System. The CCNS-4 interfaces with the flight computer to manage and control the aerial survey. Digital USGS quadrangle maps are used for planning, determining flight altitude, establishing exposure, overlap, and flight line position parameters. The latitude and longitude of each exposure is planned before the aerial mission, and used for automatic camera control. Waypoint GRAFNA V software will be used for post processing. Aerial Camera For this project a Zeiss RMK TOP precision aerial mapping camera will be used. It is equipped with low distortion, high-resolution lenses and designed for vertical aerial photography with a 9" x 9" format. Aerial Film Only new, AgfaX-lOO color aerial film will be used. The film will be stored and used in compliance to the manufacturer's specifications. 't'3!t~ ,,' 3 ,jl~ Ii i'i",,~i/! ~ Film Storage and Ownership The exposed aerial film is the property of the City and will be delivered immediately upon request. Unless otherwise requested, The Sidwell Company will store the aerial film under appropriate atmospheric conditions for a period of 10 years at no additional cost to the City. DIGITAL ANALYTICAL AERIAL TRIANGULATION Introduction Photogrammetric production requires the orientation data for each photograph at the moment of exposure. Since the camera platform is in constant motion, the orientation cannot be achieved via simple measurement. Airborne GPS flight data, ground based GPS survey data and camera calibration information is used in a process called Digital Analytical Aerial Triangulation (DAA T), which uses complex mathematical formulas, to solve for the photo orientation, position and photo pass point coordinates. Digital softcopy photogrammetric workstations and digital AAT techniques will be used for the aerial triangulation process. Use of digital technology will reduce the handling and damaging of original film. Digital analytical aerial triangulation will be performed using ImageStation Match-AT software for point marking, mensuration and simultaneous block adjustment. Tie Points Tie points will be used to join adjacent photographs in the same flight line and adjacent flight lines. They will be selected and numbered by automatic or semi-automatic techniques. Points are selected using image correlation techniques of pyramid images for each stereo model. The software contains constraints, which will reject erroneous points. Block Measurement and Adjustment The photo image tie points will be measured automatically in the digital environment and processed using ImageStation Match-AT software. Ground control points will be measured in a semi-automatic mode. The data will be organized for adjustment processing in strips, sub- blocks, and then blocks. This package has error detection and flagging routines as well as earth curvature correction. Aerial Triangulation Report Upon completion of aerial triangulation, a report will be prepared summarizing the process and detailing the results for adjusted control and tie points. Accuracy and Quality Assurance The accuracy of the aerotriangulation adjustment will be approximately 1/8,000 of the fly height. Ground control configurations are selected which will provide not only the required number of points, but also will aid in the detection and resolution of error. Part of the function of the aerotriangulation software is the ability to isolate and identify points, which may suffer from errors of control, point miss-identification, or incorrect point numbers. These points will ~~ 5 ~)\. " 1,= , ;..:};ih]:;P Image Rectification The digital orthophoto process is one that corrects the image for horizontal displacement due to relief and camera tilt. Digital differential rectification will be performed using Ortho Pro by 2/1 Imaging and OrthoMaster by INPHO. The raw images will be loaded and viewed. Interior orientation will be performed using data from the camera calibration report. Exterior orientation will be performed using the analytical aerial triangulation control data. DEM data previously collected will be processed to create a triangular irregular network or TIN file. This TIN file forms the surface to which the raw image is corrected. The properly oriented image is then re-sampled pixel by pixel considering the TIN file to produce an image that is orthographically correct at the ground surface and is at a final ground resolution pixel size. Image Radiometry Image brightness will be represented by 256 levels ranging from zero to 255. The specific range selected for the digital orthophotos will display the most pleasing photo image. Special attention will be paid to the light and dark areas to ensure that valuable image detail is not lost in shadows or areas of high reflection. Mosaicking The ortho rectified images will be mosaicked together using ImageStation Ortho Vista software to form a continuous image blanket for an entire area identified by a particular photo scale. Each image will be geo-referenced so as to appear in their correct geographic location when viewed. These images will reference the State Plane Coordinate System. Mosaicking will be accomplished by defining the optimum boundary within image overlap at which one image should blend into the next. This boundary will be selected so as to minimize mosaicking through objects that would reveal a change in photographic perspective. The blending will be feathered to minimize the appearance of separate images. The resulting mosaicked orthophoto will then be divided into tiles. Image Tiles The images will be cut into grid-based tiles for storage and retrieval. The tiles will butt match and form a continuous image when viewed together. The size of the files will be such that they are appropriate for the City's applications. Image Output Digital orthophoto images will be delivered in TIFF file format with world files. Image tiles willcbe transferred uncompressed to an external hard drive for digital delivery to the City and County. In addition, one set of compressed image tiles in MrSid or ECW format will be included for delivery. ,,:""^?' 7 " : PROJECT MAP II D '\i::1i[i:~ City of Salina Project Boundary '" o o a l=> (] .," 9 I I J 'itcll!
