National Agricultural Imagery Program (NAIP), Minnesota, 2023, Digital Orthorectified Images (DOQ)

This dataset contains 4-band natural color and false color infrared (CIR) imagery from the National Agricultural Imagery Program (NAIP). 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 one year of acquisition.<br/><br/>The source files are 30-centimeter (approx. 1-foot) ground sample distance (GSD) ortho imagery rectified to within +/- 4 meters to reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP) or from the National Agriculture Imagery Program (NAIP). The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 +/- 30 pixel buffer on all four sides. NAIP imagery is formatted to the UTM coordinate system using the North American Datum of 1983 (NAD83). NAIP imagery may contain as much as 10% cloud cover per tile.<br/><br/>The county mosaic files downloadable from the USDA NRCS Geospatial Data Gateway (natural color and color infrared) were generated by compressing NAIP imagery that covers the county extent. Two types of compression may be used for NAIP imagery: MrSID and JPEG 2000. The target value for the compression ratio is 40:1 for imagery.<br/><br/>The Minnesota Geospatial Information Office (MnGeo) created this metadata record to describe the entire NAIP 2023 dataset, using information from FPAC-BC-GEO metadata. Each county file available from the USDA NRCS Geospatial Data Gateway is accompanied by the original FPAC-BC-GEO metadata for that county.
