Abstract This data set contains polygons delineating the seams boundary between acquired imagery used in the creation of DOQQs and compressed county mosaic (CCM). The DOQQ and CCM products were created from imagery acquired in the National Agriculture Imagery Program (NAIP). These seam polygons can be used as a tool in determining the image source and date of each portion of the DOQQ or the CCM. The 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. The NAIP provides two main products: 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy 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 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. The NAIP quarter quads are formatted to the UTM coordinate system using the North American Datum of 1983 (NAD83).

Purpose This index will aid USDA Agencies in identifying and delineating source acquisition date boundaries for the compressed county mosaic as they administer USDA programs for their customers.

Logical Consistency Report USDA-FSA Aerial Photography Field Office relies on the integrity of the original data collection which was performed by private contractors. Data integrity was validated by the responsible private contractor or sub-contractor. Polygon and chain-node topology present. There are no duplicate arcs and no dangling nodes. The data set contains polygons that do not overlap, there are no polygons that are entered twice, and all areas are completely described. The area features are topologically structured with nodes at all intersections. Attribution of the digital data set includes polygon areas that define the portion of visible imagery used representing the same source acquisition date, with no gaps in coverage.

Completeness Report To the best knowledge of the USDA-FSA Aerial Photography Field Office this digital data set is complete with no required elements left unrepresented according to contract specifications.

Process Step

Process Description This ESRI shape file was created using custom-developed software and the freeware 'shapelib' library. The list of quarter quadrangles was extracted from government-furnished information. The extent of the quarter quadrangle polygons is based the computation of UTM coordinates from the government-furnished geographic bounds. The ordering scheme for insertion of the digital orthophotos is based on a last-in-last-on-top scheme.
