NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S.. A primary goal of the NAIP program is to enable availability of ortho imagery within sixty days of acquisition. The NAIP provides 0.6 meter GSD ortho imagery rectified within +/- 6 meters to true ground at a 95% confidence level. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 (plus or minus 30) pixel buffer on all four sides. The NAIP quarter quads are formatted to the UTM coordinate system using the North American Datum of 1983 (NAD83). Quarter quadrangles were combined to create individual county mosaic's for Oklahoma's 77 counties and then compressed with LizardTech technology (MrSid) and made available to the public as compressed county mosaics (CCM). These MrSid CCM's were processed by the Oklahoma Office of Geographic Information to create jpeg compressed quarter quad geotiffs in the EPSG 4326 (WGS84) coordinate system. These compressed quarter-quads were further processed into 512,512 pixel tiles for distribution through the Geoserver web application, OKMaps. NAIP imagery is available for distribution within 60 days of the end of a flying season and is intended to provide current information of agricultural conditions in support of USDA farm programs. For USDA Farm Service Agency, the 0.6 meter GSD product provides an ortho image base for Common Land Unit boundaries and other data sets. The 0.6 meter NAIP imagery is generally acquired in projects covering full states in cooperation with state government and other federal agencies who use the imagery for a variety of purposes including land use planning and natural resource assessment. With an annual cycle, NAIP is also used for disaster response often providing the most current pre-event imagery. While suitable for a variety of uses the 2 meter GSD NAIP imagery is primarily intended to assess crop condition and compliance to USDA farm program conditions. The 2 meter imagery is generally acquired only for agricultural areas within state projects.
