Product DescriptionThe National Aerial Photography Program (NAPP) provides a standardized set of cloud-free aerial photographs covering the conterminous U.S. over five-to-seven year cycles. The program began in 1987 and continues to be our most recent and consistent source of high-quality aerial photographddddddddddddddy. The photographs were acquired from an altitude of 20,000 feet and are available in black & white (B/W) or color infrared (CIR), depending on location and date. Each photo is centered on one-quarter section of a 7.5-minute USGS quadrangle, and covers approximately a 5.5 x 5.5 mile area.

The above sizes may vary due to scanning more than just image data. The files are created in TIFF format. With our policy to scan the surrounding metadata and the addition of the USGS logo the actual image size will generally be larger than the estimates above.
