USGS National Aerial Photography Program

Program: This "was coordinated by the USGS as an interagency project to acquire cloud-free aerial photographs at an altitude of 20,000 feet above mean terrain elevation. 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
