Answer: This depends on the purpose for which the photograph is to be used. For land cover mapping, most people prefer color infrared (CIR). However, photography is not always available in CIR. In this case, black-and-white panchromatic (B/W) photography is an option. Black-and-white photography is suggested for large coverage areas because it is less expensive when produced as paper prints. Hunters, planners, and cartographers tend to use B/W photography. If the photograph is a gift or is to be used as a wall hanging, film type may not be as serious a consideration.
Photographic reproduction of images from the USGS film archives ceased on September 3, 2004. For those who specifically need paper or film products, there is a list of USGS Business Partners who provide aerial photographic research and image printing services. |
