NAIP = USDA FSA National Agricultural Imagery Program: 2003 - Present

The National Agriculture Imagery Program (NAIP) acquires aerial imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to make digital orthorectified photography available to governmental agencies and the public within a year of acquisition. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using NAD83. NAIP imagery may contain as much as 10% cloud cover per tile. The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center distributes NAIP products in JPEG2000 format, which is a compressed file with embedded georeferencing information.
