Description:
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.

Attribute_Accuracy_Report:
All data have been reviewed for correct application of
attributes and are accurate to current conditions.
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_Description:
Seamline shapefiles were created within Sanborn's proprietary
seaming software. These files were converted from raster format to polygon vector
format (ESRI SHAPEFILES). During the conversion process, specific information
related to the camera type used and dates of photography were added to the data
as attributes. Inaddition, a shape area attribute was calculated.
