Proposal Option 2 — Digital Aerial Orthophotography Proiect Scone The scope of this project is to provide 7.5 cm (3") pixel resolution color digital Ortho - photography for the City. The Ortho - photography will be captured with a large format calibrated digital aerial mapping camera. It will be ortho- rectified using an accurate DTM created from the digital imagery (accuracy and additional specs below). The project limits will be based upon the attached boundary description document (Attachment 5). The City desires to have one point of contact for all interactions with the Vendor in regards to the Digital Aerial Orthophotography Project. The City also desires the option to change the point of contact as needed during the course of the agreement, at the City's discretion. The city desires to enter into a three year agreement with the vendor with the option to extend the agreement for an additional two years. In the sealed fee proposal, the Vendor will provide four (4) quotes based on the project requirements listed below for the following deliverable schedules: Initial Three Year Contract Schedules: Delivery Schedule One: Imagery flown and delivered in years one, two and three Delivery Schedule Two: Imagery flown and delivered in year one and year three. Extended Fourth and Fifth Year Contract Schedules: Delivery Schedule Three: Imagery flown and delivered in year four and year five. Delivery Schedule Four: Imagery flown and delivered in year five. Proiect Rcuuirements: Horizontal Accurac The datum for horizontal adjustments and positions must be the North American Datum of 1983 (NAD 83). The datum for vertical adjustments and elevations will be the North American Vertical Datum of 1988 (NA VD 88). Further, it must be adjusted to the 2007 EPOCH adjustment by the County of Orange to account for ground shift in Orange County that has caused 2.2' average shift from the 1988 NAD datum. All horizontal values must be published in the California Coordinate System 1983 (CCS83), Zone 6, State Plane values in U.S. Survey Feet. The ortho images must be tied to the current Geodetic control network from the Orange County Survey Department. They must also have a horizontal accuracy of plus /minus one foot or better throughout the project area. Flight Camuai All aerial photography must be performed in accordance with specifications established by the American Society of Photograminetry and Remote Sensing. A large format, calibrated digital mapping camera with forward motion compensation must be used. The vendor will deliver a Camera Calibration Certificate for the camera used. Planning and acquisition will be performed under the direction of an ASPRS Certified 25H -33 Page 5of10
