NHAP Imagery

The NHAP program was started in 1978 by a number of Federal agencies combining their funds and knowledge to provide the greatest range of users with consistent and systematic aerial photography coverage of the United States.

The date range of NHAP photography available is 1980 - 1987. Two scales of photography were secured simultaneously; a scale of 1:80,000 is exposed on black-and-white panchromatic film, and the 1:58,000 is exposed on color infrared positive film.

The APFO has a complete file of the 1:58,000 CIR film. Both color infrared and black-and-white reproductions can be produced from this film base.
