Metadata: Identification_Information: Citation: Citation_Information: Originator: USDA-FSA Aerial Photography Field Office Title: Index of source acquisition dates. Publication_Date: 20050911 Edition: Version Geospatial_Data_Presentation_Form: vector digital data Publication_Information: Publication_Place: Salt Lake City, Utah Publisher: USDA-FSA Aerial Photography Field Office Description: Abstract: This data set contains lines and/or polygons delineating the boundary between DOQQ imagery used in the creation of a compressed county mosaic (CCM). 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. 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 a 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); 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. Purpose: This index will aid USDA Service Centers in identifying and delineating source acquisition date boundaries for the compressed county mosaic as they administer USDA programs for their customers.

Process_Step: Process_Description: This ESRI shape file was created using custom-developed software and the freeware 'shapelib' library. The list of quarter quandrangles 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.
