Title
National Agricultural Imagery Program (NAIP), 2021, Digital Orthorectified Images (DOQ) [Minnesota]
Description
This data set 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. The source files are 60-centimeter (approx. 2-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 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. 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. MrSID compression was used. Target value for the compression ratio is 40:1. The Minnesota Geospatial Information Office (MnGeo) created this metadata record to describe the entire NAIP 2021 dataset, using information from FSA metadata. Each county file available from the USDA NRCS Geospatial Data Gateway is accompanied by the original FSA metadata for that county., NAIP imagery is typically 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 1 meter and 1/2 meter GSD product provides an ortho image base for Common Land Unit boundaries and other data sets. The 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. NAIP is also used for disaster response often providing the most current pre-event imagery., Summer and Fall 2021. See the IDATE attribute in the seamline shapefile for the state or accompanying each county download to find out the date(s) that the source imagery was acquired. Options to access the dates: 1. A seamline shapefile for Minnesota may be downloaded from NRCS: https://nrcs.app.box.com/v/naip/folder/152290152166 2. The shapefiles are included with the MrSID county mosaics downloadable from NRCS
