Section II. DATA STORED IN THE BANK 



In establishing the bank, Engineer Divisions or Districts and other 

 government agencies and nongovernment offices are contacted for available 

 photographs of coastal areas. The following technical information is 

 requested: date, scale and security classification of photographs, focal 

 length of camera used, film size, ground location covered by the imagery, 

 agency or company project number of the flight, and altitude of aircraft. 

 The index is limited to cataloging mostly unclassified, vertical and oblique 

 photographs that cover the coastal zone for a distance of 5 miles inland 

 from the shoreline. Bays, estuaries, and offshore islands are included. 

 Appendix A lists the sources excluding Corps of Engineers Division and 

 District offices, that have made an input to the Coastal Imagery Data Bank 

 through fiscal year 1972. 



Section III. FORMAT OF DATA STORED IN THE BANK 



Data describing the photography held by the offices or agencies are 

 stored on aperture cards. Each aperture card is a standard computer card 

 with a window in which a 35-millimeter negative film is attached 

 (Figure 2) . 



These cards can be viewed in any standard aperture card or microfiche 

 reader. The image on the film consists of a DMATC (formerly Army Map 

 Service) 1 :250,000-scale topographic map (Figures 3 and 4) with an over- 

 lay depicting the flight line and extent of coverage obtained from a photo- 

 graphic mission. Also included on the film image are the technical data 

 described in Section II. Figures 5 through 8 are enlargements of four 

 aperture card film images showing four missions flown over the North Pacific 

 coast. 



Additionally, each aperture card is keypunched with coded data de- 

 scribing the photography. Appendix B lists the type of information that 

 is punched on each card; Appendix C defines the state abbreviation codes. 

 Appendix D is a listing of the aperture cards completed as of 30 June 1972. 



Section IV. USE OF BANK 



When indexing for each Engineer Division or District is complete, 

 these offices are provided with a set of index cards describing the 

 photography taken within their area. To view the indexed photographs 

 or to obtain copies, the referenced agency holding the photographs must 

 be contacted. A fee may be required to obtain copies of the desired 

 imagery. 



Section V. FUTURE CONSIDERATIONS 



It is planned to continue indexing all available photography of 

 the coasts of the nation on an Engineer Division or District basis
