- Description
- Aerial Photography- Furnish aerial photographic services and related supplies in accordance with the requirements, specifications, terms, conditions specified herein. This will be an Indefinite Delivery-Indefinite Qauntity contract for three years. Up to three contractors will be awarded master contracts. Two task orders will also be awarded at the time of original award. The general scope is to procure vertical aerial photography to typically support stream surveys, vegetation management, restoration projects, pre- and post-project monitoring, site design, post fire planning, natural resource inventory, orthophotography, and extraction of data by means of photogrammetric measurements. Aerial Camera Specifications: Tested and calibrated precision aerial cameras for taking aerial photographs are required. Only camera systems which meet the requirements of these specifications, as determined by a current USGS “Report of Calibration” test report, shall be used. A camera system “Report of Calibration” will not be acceptable if more than three (3) years old at the scheduled date for receipt of offers. Lens Focal Length primarily needed is the 12 inch (305mm) and 8 ¼ inch (210mm). Filters used should be antivignetting for normal color film or a yellow filter for color infrared (CIR). Camera Operation: The camera and its mount shall be checked for proper installation prior to each mission. Particular attention shall be given to electrical circuits which control fiducial and camera data box lights and to the vacuum supply. In conformance with conventional photogrammetric practice, it is the preference of the Government that the contractor use camera configurations, that when installed in the aircraft, advance film parallel to the line of flight. The camera mount shall be regularly serviced and maintained and shall be insulated against aircraft vibration. Camera Accessories: An automatic exposure control device is permitted, but a manual override capability is required for some types of terrain to achieve proper exposure. Aerial Film: Kodak 2444 Aerocolor III Negative or equal. Kodak 1443 infrared film or equal when color infrared is requested. All aerial film used on a project item shall be from one film type and manufacturer and be purchased by the Contractor. Extreme care shall be exercised to insure proper exposure and processing of film to minimize vignetting due to differential exposure. This differential shall not exceed that which would result from a basic ¼ stop difference in exposure. All aerial film shall be free from chemicals, stains, tears, scratches, abrasions, water marks, finger marks, lint, dirt, and other physical defects. The imagery shall be clear and sharp in detail and uniform in density. It shall be free from light streaks, static marks, and other defects that would interfere with the intended purpose. All film shall be thoroughly fixed and washed to insure freedom from chemicals and shall be of archival quality. Storage, exposure, and handling of all photographic materials shall be in accordance with the manufacturer’s recommendation. The film shall not be rolled tightly on spools or in any way stretched, buckled, distorted, or exposed to excessive heat. Maximum Film Roll Length: 200 feet. Approximate Photographic Period: May 1 through September 30 Minimum Sun Angle: 50 Degrees. Photography shall be undertaken only during that portion of the day when the sun angle exceeds the minimum specified. Terrain Conditions: The ground cover is mostly forest and mountainous terrain. Photographic Conditions: Photography shall be undertaken when skies are clear, free from smoke, clouds, cloud shadows, excessive haze, and well-defined images can be resolved. The ground shall be free from snow below timberline. Overlaps: Endlap: Optimum 62%, Minimum 57%, Maximum 67% Sidelap: Optimum 30%, Minimum 20%, Maximum 45% Horizontal Deviation: Deviation from the plotted position of the flight line in excess of five (5) percent of a full print may cause rejection of any or all of the flight line. Scale Deviation: Deviation from the Official Scale will be no more than 25%. Crab: Any series of two or more photographs crabbed in excess of five degrees (5°) as measured between photographs in line and between adjoining lines may cause rejection of any or all of that particular flight line. Tilt: Exposure made with the optical axis of the camera in a vertical position is desired. Tilt (departure from the vertical) on any exposure exceeding four degrees (4º) or relative tilt between any two successive exposures exceeding six degrees (6°) may be cause for rejection of any or all of the flight line. Flight Plan Data: The Contractor will be furnished the Official Flight Plan Data. The Official Flight Plan Data will determine project location, flight direction, datum breaks, and the flight altitude of each line above mean sea level. The Contractor will be furnished the latitude and longitude coordinates, expressed in degrees, minutes, seconds, and decimal seconds, of all beginning and ending terminal points of project flight lines. Data shall be in ASCII text format. Small locator maps will also be provided. Film Titling: Identifying data shall be placed in line along the most northerly flight edge of the aerial exposures of north-south flights and shall be placed along the western edge of the exposure in east-west flights. Flights along streams or NW, NE, SW, SE lines shall be titled on the upstream edge or the highest terrain edge. Titling shall include Flight Date, Government Agency (USFS), Photo Scale, Project Code, Run Number (no longer use the roll number) and Exposure Number (Number in unbroken series beginning with 1, not 001 or 01.). In addition, the local standard time of exposure (PST) shall be titled on first and last exposure of each flight line and at each break in flight line, including breaks due to reflights. Example: 8-8-08 10:14 USFS 1:6000 08026-SIU 1-1 (Date) (Time) (Agency) (Scale) ( Project Code) (Run #-Exposure#) The characters used in titling shall be standard block lettering 6.35mm (1/4 inch) high. They shall be sharp, legible, and uniformly applied with non-flaking black ink. The titling shall be placed on the non-emulsion side of the film and may be applied by use of an ink drawing pen or stamp. No smears or transfer of marking ink to other parts of the film roll will be permitted. Prints: Photographic papers of proper contrast must be used in making suitable prints to bring out all the details of the film image including clear identification of fiducials. Full size (9”x 9”, 23cm x 23cm) color contacts must be printed for the best detail and color variances in riparian vegetation, stream channel debris, soils, and forest canopy. Prints must be properly developed and thoroughly fixed and washed. They must be clean and free from stains, blemishes, uneven spots, air bells, fog, and finger marks. Digital Photo Data File: Contractor shall prepare a digital photo-center data file for all aerial photography acquired under this solicitation. The file(s) shall be provided in ASCII comma delimited text format. A comma delimited header line (Project Description) shall precede the data in each file as shown in the example below. The latitude/longitude coordinates shall be expressed in decimal degrees with five (5) decimal places of precision (47.71936, -120.41498), formatted to NAD83 datum, and be accurate within 30 meters (100 feet) of the true photo center location. Longitude must be expressed as negative space for western hemisphere. Higher accuracies obtained through use of GPS technology are desirable but not required. The photo-center data shall include the following attributes: Project Description: This should be the first line of all project exposure data and shall contain, at a minimum, the following: Project code, Project name, State abbreviation, Photo scale, Film, Number of film rolls, Coordinate system datum, Coordinate collection method, Estimated accuracy of coordinates, Exposure data file creation date (MMDDYYYY) Example: 07099-DES, Slapdap Fire, OR, 12K, Kodak 2444, 2, NAD83, GPS, 50m, 08152007 Exposure Data: This contains coordinates and other data, for each individual exposure for the entire project. The geographic coordinate data shall be expressed in decimal degrees, formatted to NAD83, and be accurate to within 100 feet (30m) of the true photo center location. The Exposure Data shall contain the following data: Flight line number, Exposure number, Exposure date (MMDDYYYY), Latitude (DD.DDDDD), Longitude (-DDD.DDDDD) Example: 2, 1, 08142007, 47.71936,-121.41498 Cascading set aside for HUB Zone contractors. If unable to award to at least three qualified firms at a fair and reasonable price, then Small Businesses not in a HUB Zone area will be considered. The solicitation will be posted on FEDBIZOPPS on or about April 28, 2008. For additional information, contact David Hallen at 503-668-1667.
