Aerial photographs are an important tool in cartography and a number of other professions.
Land use planners, real estate developers, lawyers, environmental specialists, and many other professionals rely on detailed and timely aerial photographs. Until 1975, there was no systematic approach to locate an aerial photograph, or series of photographs, quickly and easily. All fields can be displayed, and 12 of the 13 fields can be searched. Not all fields, however, contain data for every record. Each record in the contributor data base contains the name, address, and phone number of a contributor.
