- Title
- National Agricultural Imagery Program (NAIP), 2005, Geo-rectified Images [Minnesota]
- Description
- This data set contains natural color 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 2 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within 10 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP). 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. This file was generated by compressing NAIP quarter quadrangle tiles that cover a county. MrSID compression, with mosaic option, was used. Target values for the compression ratio are (15:1) and MrSID Generation 3. (Note: MnGeo created this metadata record using information from Farm Service Agency metadata. Each county file is accompanied by the original FSA metadata for that county.), NAIP imagery serves as a base for Farm Service Center GIS applications and is used to administer USDA commodity support programs and conservation planning. The MrSID mosaics were compiled to provide a data format that is highly compressed (20:1) with minimal data loss. NAIP imagery may be distributed on an interim basis to meet USDA program requirements. The interim product is a compressed county mosaic. Users should be aware that the interim compressed county mosaic may contain defects and have horizontal accuracy less than the specified tolerances. Defective imagery may be replaced within one year of image acquisition date., Summer 2005.
