The Mississippi County aerial photography DVD contains natural color imagery from 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 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 5 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.
     
      Be aware that the interim compressed county mosaic may contain defects and have horizontal accuracy less than the above specified tolerances.

Imagery has been provided by Mississippi Automated Resource Information System. (MARIS). The USDA-FSA Aerial Photography Field Office.(APFO),  National Agriculture Imagery Program (NAIP).
