USDA-FSA Aerial Photography Field Office20171122Index of source acquisition dates.Versionvector digital dataSalt Lake City, UtahUSDA-FSA Aerial Photography Field OfficeThis 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 60cm GSD ortho imagery rectified
within +/- 4 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).This index aids USDA Agencies in identifying source acquisition
date boundaries as they administer USDA programs for their customers.20171122Esri shapefile creation date.Irregular-89.082257-88.48440043.26242642.800058NonefarmingDigitalMosaicOrtho ImageryUnited States Department of Agriculture (USDA)Acquisition DateNoneUSAFSAField Service CenterAerial Photography Field OfficeAPFOUSDAUnited States Department of Agriculture (USDA)Jefferson CO., WI FSAFIPS 55055JeffersonWisconsinNoneNone, The USDA-FSA Aerial Photography Field Office asks

attributes and are accurate to current conditions.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.To the best knowledge of the USDA-FSA Aerial Photography
