Summary
Abstract: The National Aerial Photography Program (NAPP) is an interagency
Federal effort coordinated by the USGS, which uses NAPP products to
revise maps. Other agencies have varied uses for these photographs,
which, are taken on a 5- to 7-year cycle and produced to rigorous
specifications. The NAPP program encompasses each of the lower 48
states and Hawaii. The photos are acquired from airplanes flying at
an altitude of 20,000 feet using a 6 inch focal length camera
resulting in a scale of 1:40,000. Each 9-by 9-inch photo (without
enlargement) covers an area of slightly more than 5 miles on each
side. Flightlines for the NAPP program are flown in a north-to-south
direction through the east and west halves of 7.5-minute
quadrangles.

Purpose: The original purpose of the NAPP program which was established in
1987, was to provide the USGS with accurate and cloud-free
photographs that would assist them in the creation and revision of
USA topographic maps.

Quality Process_Description:
NAPP photographs are obtained on 9-inch film from an altitude of
20,000 feet above mean terrain elevation, and are centered on quarters
of 7.5-minute quadrangles. Strict specifications regarding sun angle,
cloud cover, minimal haze, stereoscopic coverage, and image inspection
were followed.
