Each color infrared photo shows an area of An aerial photo of the area between Lititz and Lancaster. about 68 square miles and each black-and-white photo depicts about 130 square miles. Even from 40,000 feet, features as small as houses and boats are distinguished because of the quality and high resolution of the NHAP photographs, said John Wood, chief of the National Car tographic Information Center at the USGS National Center in Reston, Va. Larger features such as air fields, parks, large buildings, highways, lakes and streams are easily identifiable. For example, the NHAP photo of the Pittsburgh area clearly shows Point State Park, the Civic Arena and Three Rivers Stadium. On the color-infrared photos, areas of healthy vegetation such as forests, swamps, irrigated croplands and urban parks appear in red, while areas of sparse or no vegetation appear in shades of blue, gray and brown. Bodies of water, as in conventional color photographs, range from light blue to black. Wood said that under the multi agency cooperative NHAP program, more than 87 percent of the area in the 48 conterminous states has been photographed, and complete coverage of the 48 states is expected by the end of 1986 Federal agencies that contribute to the program include the depart ments of Agriculture, Defense, Commerce and Interior and the Tennessee Valley Authority The high quality of NHAP photographs is the result of ex posing film in precision aerial cameras during near-optimum weather and seasonal conditions, plus the application of stringent inspection and processing procedures before the USGS accepts the photographs from aerial surveying and map ping contractors Photographs produced under the program are intended primarily for mapping, scientific research, and resource and land-use plan ning purposes, but Wood said they can also appeal to people who want high-altitude views of their homes, farms, neighborhoods or other favorite spots. The photographs can be useful additions to map collections and make attractive wall hangings. Prints of the high-altitude photographs are available in standard 9-by-9-inch size, with enlargements available in sizes ranging up to 36-by-36 inches. Costs are $5 for a 9-by-9-inch black-and white print, $l5 for a 9-by-9-inch color-infrared print, and up to $7O for a 36-by-36-inch color-infrared enlargement. Also available are photographic prints enlarged to 1:24,000 scale to match 1:24,000- scale topographic maps for the same areas. Costs are $25 for a black-and-white print and $5O for a color-infrared print. The black-and-white and color infrared photographs are taken at an altitude of 40,000 feet above the ground with two 9-by-9-inch-format aerial cameras. A 6-inch focal length camera loaded with black and-white film produces photographs at a scale of 1 80,000 (one inch on a photograph represents about 1 25 miles on the ground) Photographs from an 8 25-mch focal-length camera loaded with color-infrared film are at a scale of 1-58,000 (one inch represents almost 1 mile).
