Mississippi Compressed County Mosaics

Abstract:
The U S Department of Agriculture - Farm Services Agency (USDA-FSA) NAIP program is designed to acquire natural color digital ortho imagery during the agricultural growing seasons in the continental U.S. This NAIP product provides 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 Zones 15 (west) and 16 (east). 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.
For further information concerning the NAIP and other products from the USDA –APFO, visit www.apfo.usda.gov

Purpose:
NAIP imagery may be distributed on an interim basis to meet USDA program requirements. The interim product is a compressed county mosaic image file. 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. .
