The DOQQ and CCM products were created from imagery acquired in the National Agriculture Imagery Program (NAIP). These boundary lines can be used as a tool in determining the image source and date of each portion of the CCM. The boundary lines separating each DOQQ may be the actual seam line location or an approximation. This is because the various vendors acquiring and processing the data use different algorithms to create the DOQQ and CCM products. Since the seam line may be an approximation, portions of the CCM along the boundary may actually come from the imagery on the other side of the seam line. 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 +/- 5 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP) or from the National Agriculture Imagery Program (NAIP); 1 meter GSD ortho imagery rectified to within +/- 6 meters to true ground. 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. Two types of compression may be used for 2008 NAIP imagery: MrSID and JPEG 2000. Target values for the compression ratio are (15:1). Purpose: This index will aid USDA Service Centers in identifying and delineating source acquistion date boundaries for the compressed county mosaic as they administer USDA programs for their customers.

The attribute data was collected during the contracting and inspection process and stored in Oracle database tables. This data was extracted from the Oracle database and joined to a national data set of quarter quadrangle polygons using the south east corner coordinate as the primary join key. An automated process was used to select the quarter quadrangles that cover each county from the national data set and then exported with the desired attributes to create this shape file data set.
