Identification_Information: Citation: Citation_Information: Originator: USDA-FSA Aerial Photography Field Office Title: Index of source acquisition dates. Publication_Date: 20130918 Edition: Version 1 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 polygons delineating the seamline boundaries of imagery acquired as part of the National Agriculture Imagery Program (NAIP), and used in the creation of DOQQs and compressed county mosaics (CCM). 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 4 band digital ortho imagery from airborne and/or space based platforms during the agricultural growing seasons in the U.S.. A primary goal of the NAIP program is to enable availability of ortho imagery within sixty days of acquisition. The NAIP provides 1 meter or 1/2 meter GSD ortho imagery rectified within +/- 6 meters to true ground at a 95% confidence level. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 (plus or minus 30) pixel 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 aids USDA Agencies in identifying 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. The dataset is comprised of polygons delineating portions of each exposure used as source data for each part of the NAIP imagery, with no gaps in coverage. Attribution includes acquisition dates and times. 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.
