7、ircular Error (CE) (90 percent assurance). 3.3 product ident ifier. Each GAP will be identified by installation name, coordinates, country name (country code) , and BE number (if available). Each sheet necessary to provide coverage of a site will have an individual stock number. 3.4 product attribut
8、es. 3.4.1 productio n. The GAP will normally be produced by plane rectification of latest date suitable source materials available to DMA. A plane rectification, which removes image projection distortions due to camera roll, pitch and yaw, is a suitable procedure for producing GAPs since airfields a
9、re essentially located on level terrain and there is little or no image distortion due to terrain relief. 3.4.2 Orthorect ified imaaerv . Under some circumstances, there may be a valid requirement to produce a GAP in an area where terrain relief is greater than would normally be expected at an airfi
10、eld. In that circumstance, if the combination of relief and image obliquity angle results in a theoretical absolute horizontal error greater than 109 feet CE, that airfield/installation will be considered a candidate for production using orthorectified imagery. formal decision to produce or not to p
11、roduce. DMA(PR) will coordinate with the requesting customer and determine if the candidate GAP, using orthorectified imagery, will meet the requesting customers requirements. Each such candidate GAP will be referred to DMA(PR) for 3.4.3 Source mater ia1 date . Source materials older than three year
12、s will not be used. three years to insure currency of detail. Maintenance updates should be prioritized with new area requirements and submitted when operational use of the data has been seriously degraded by major changes to the primary movement surfaces of the airfield. GAPs should be evaluated ev
13、ery * 3.4.4 Scale. GAPS will normally be produced at a scale of 1:6,000. Although multiple GAPs will be used to provide complete coverage of the area of interest, alternative scales may be available to accommodate large areas. These instances will be thoroughly reviewed by DMA and the requesting com
14、mand on a case by case basis. NOTE: Scale changes may affect grid spacing and product accuracy evaluation. 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-NIL-G-89IIOb 99999Ob II977213 706 MIL-G-89106 3.4.5 .

The following information will be carried in the GAPS margin or in an area of the GAP that does not obscure the airfield. a. Installation name, country code, and BE number (if availab

Should product evaluation procedures indicate an accuracy worse than 109 feet at 90% reliability, DMA(PR) will coordinate with the customer to determine if the product is usable, wil

If more than one sheet is required to cover large airfields, the maximum size of any sheet will be 24 inches X 30 inches (60.
23、96 X 76.20 centimeters). 3.8 BeDroduW . Reproduction of GAPs will be accomplished by standard quality photographic processing. a. Photographic copies will be produced flat for distribution unless the print quantity requirement exceeds 200. Over 200, lithographic copies will be produced and the user
24、must specify “flat“ or “folded“, the latter being an eight panel fold. b.

26、the GP Listing will cease, and all recipients of DMA catalogs who have requested that publication containing Gridded Photos will have the current inventory. 4. QUALITY ASSURANCE PROVISIONS for insoection . Unless otherwise specified in 4.1 Resomsibilitv * the contract or purchase order, the contract
27、or is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements speci
28、fied herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. . All items shall meet all 4.1.1 pesr
29、o nsibili tv for comoliance * requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements. in the specification shall not relieve the contractor of the
30、 responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements; however, this does not auth
31、orize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.2 Classificat ion of insnection .
