The photographs were taken with a 6-inch focal length lens at a scale of 1:40,000. Coverage over the conterminous United States includes both black-and-white (BW) and color infrared (CIR) aerial photographs."
Images available: The images in this data set were collected between 1987 and 2007. All the images are available on EarthExplorer
