Imagery Aerial Photography NAPP aerial photography
Description - The 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 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.

This is a KMZ (compressed KML) file containing NAPP imagery of the GCE domain from 1988 (CIR), 1993 (B&W), and 1999 (CIR) for use in Google Earth.
