Color Infrared Imagery (CIR)
2007 – 1 Meter, Ortho Rectified
Mississippi Compressed County Mosaics / Individual DOQQ tiffs
The US 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 United States. Under contract from the Mississippi Forestry Commission, the Mississippi Institute for Forest Inventory and the Mississippi Army National Guard, Photo Science simultaneously acquired, in addition to the natural color 2007 NAIP, near infrared spectral band (1064 nm) and produced quarter quads of false-color infrared imagery. This imagery is referenced the same as the 2007 - 1 meter NAIP. This CIR 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 this imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. CIR quarter quads are formatted to the UTM coordinate system using NAD83 Zones 15 and 16. This imagery may contain as much as 10% cloud cover per tile. This file was generated by compressing CIR quarter quadrangle tiles that cover a county. MrSID compression, with mosaic option, was used. Target values for the compression ratio are 15:1. Metadata for a particular county is identical to the information under the NAIP 2007 true-color imagery. Photography dates are also the same.
