Metadata: Identification_Information: Citation: Citation_Information: Originator: USDA-FSA Aerial Photography Field Office Title: Lamar County Mississippi Compressed County Mosaic Publication_Date: 20050131 Publication_Information: Publication_Place: Salt Lake City, Utah Publisher: USDA FSA Aerial Photography Field Office Description: Abstract: This data set contains imagery from the National Agriculture 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. NAIP provides two main products: 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 3 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP); and, 2 meter GSD ortho imagery rectified to within +/- 10 meters of reference DOQQs. 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 (50:1) and compression levels(9) are used. Purpose: 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.

These DOQQ files are from summer 2004 color photography. The aerial imagery was rectified using USGS Government Digital Elevation Models using Intergraph's Imagestation OrthoPro Software version 4.3. The DOQQ files were compressed using Mr Sid compression software and the county composites were also created using the Mr Sid software. The composites are compressed at a 50:1 ratio.
