This data set contains imagery from the National Agriculture
Imagery Program (NAIP). The NAIP program is administered by
USDA FSA and has been established to support two main FSA
strategic goals centered on agricultural production.
These are, increase stewardship of America's natural resources
while enhancing the environment, and to ensure commodities
are procured and distributed effectively and efficiently to
increase food security. The NAIP program supports these goals by
acquiring and providing ortho imagery that has been collected
during the agricultural growing season in the U.S. The NAIP
ortho imagery is tailored to meet FSA requirements and is a
fundamental tool used to support FSA farm and conservation
programs. Ortho imagery provides an effective, intuitive
means of communication about farm program administration
between FSA and stakeholders.
New technology and innovation is identified by fostering and
maintaining a relationship with vendors and government
partners, and by keeping pace with the broader geospatial
community. As a result of these efforts the NAIP program
provides three main products: DOQQ tiles,
Compressed County Mosaics (CCM), and Seamline shape files
The Contract specifications for NAIP imagery have changed
over time reflecting agency requirements and improving
technologies. These changes include image resolution,
horizontal accuracy, coverage area, and number of bands.
In general, flying seasons are established by FSA and are
targeted for peak crop growing conditions. The NAIP
acquisition cycle is based on a minimum 3 year refresh of base
ortho imagery. The tiling format of the NAIP imagery is based
on a 3.75' x 3.75' quarter quadrangle with a 300 pixel buffer
on all four sides. NAIP quarter quads are formatted to the UTM
coordinate system using the North American Datum of 1983.
NAIP imagery may contain as much as 10% cloud cover per tile.

NAIP imagery is available for distribution within 60 days
of the end of a flying season and is intended to provide current
information of agricultural conditions in support of USDA farm
programs. For USDA Farm Service Agency, the 1 meter and 1/2 meter
GSD product provides an ortho image base for Common Land Unit
boundaries and other data sets. The 1 meter and 1/2 meter NAIP
imagery is generally acquired in projects covering full states in
cooperation with state government and other federal agencies that
use the imagery for a variety of purposes including land use
planning and natural resource assessment. The NAIP is also used
for disaster response. While suitable for a variety of uses,
prior to 2007 the 2 meter GSD NAIP imagery was primarily intended
to assess "crop condition and compliance" to USDA farm program
conditions. The 2 meter imagery was generally acquired only
for agricultural areas within state projects.

Conceptual Consistency
NAIP 3.75 minute tile file names are based
on the USGS quadrangle naming convention.
Flight planning was performed in Leica MissionPro over a
buffered boundary covering DOQQ extents provided by the USDA.
A 500m reduced resolution DEM file was used to determine
ground heights. A targeted flight altitude of approximately
21,000 feet above ground level for native 60cm image
acquisition with sidelap of 27% was used
for flight planning parameters. Five Cessna Conquests and
a Cessna 414 were utilized for acquisition, the seamline
shapefile clarifies which aircraft were used for a given area.
All aircraft were equipped with Leica
ADS100 systems where utilized for data
capture. The Leica ADS100 pushbroom sensor
has been calibrated by the manufacturer as well as validated
against a local calibration range. The calibration includes
measuring the radiometric and geometric properties of the
camera. These data are used in the Post Processing Software
to eliminate the radiometric and geometric distortion.
All aerial imagery was collected with associated GPS/IMU
data. ADS collection requires high quality IMU data for
processing and was critical for early access hosting of digital
data to the web for USDA interim access and review.
After early access web delivery was complete, all
imagery was triangulated using Leica XPro in which
the airborne GPS data was constrained to expected limits.
To validate the accuracy of the block adjustment derived from
GPS/IMU, sensor parameters and conjugate point measurements,
photo identifiable ground control points
were field surveyed within each State. These points were
surveyed using GPS techniques to produce coordinates that are
accurate to +/- 0.25 meters RMSE in XYZ. The GPS surveying
techniques utilized assured that the coordinates are derived
in the required project datum and relative to an approved
National Reference System. If the block does not fit the
control points within specifications the pass and tie
points were reviewed for blunders and weak areas. If,
after these corrections were made, the block still
does not fit the control well the GPS and IMU processing were
reviewed. Once the block has proper statistics and fits the
control to specifications, the final bundle adjustment was
made. As AT points are frequently on man-made and other
vertical features not included in the DEM, these ortho
points can only be used to indicate regions of error by the
clusters of points that predict excessive horizontal
displacement.
The final adjustments assure a high quality relative adjustment
and a high quality absolute adjustment limited to the
airborne GPS data accuracy. This process assures the final
absolute accuracy of all geopositioned imagery. Both
signalized and photo identified
ground control were used to QC and control the IMU/GPS
based aerial triangulation bundle block solution.

Surdex
Grouping Tool provides real-time updates
of the USDA APFO Image Metrics. The image technician adjusts
image correction parameters to bring the radiometric
characteristics of large groups of images within the Image
Metrics ranges. For each
project area the highest resolution DEM or LiDAR was
obtained and utilized for rectification of captured imagery.
A visual inspection of the final DEM using color cycled
classification by elevation and a shaded relief was performed
to check for gaps, corruption and gross errors.
The predicted horizontal error for each
point was added as an attribute in the SURDEX enterprise
database. An operator reviews ortho seams
in areas these predicted errors indicate horizontal error in
excess of the contract specifications. Any imagery errors
introduced by source DEM required patching from an alternate
perspective or strip of photography.
Processing hardware used included various brands of survey grade
GPS receivers, various brands and models of computers,
RAID6 storage, calibrated monitors, various brands of monitor
calibration colorimeters. Leica XPro was used for post
processing of ADS pushbroom data, triangulation and
orthorectification. SURDEX software was used to color correct
and remove bidirectional reflectance, vignetting and other
illumination trends. USDA APFO Image Metrics are measured and
images corrected to conform to the Image Metrics using
SURDEX software. GPS/IMU data was reduced to projected
coordinates in the appropriate UTM zone using
Inertial Explorer software from Novatel. Aerial Triangulation
and orthorectification was performed using Leica XPro. SURDEX
software was used to adjust for minor radiometric
variation between adjacent images. SURDEX software was used
to calculate the optimal seam path, check seam topology and
create master tiles. SURDEX ortho software generates
occlusion/smear polygons used during seam review
of steep terrain. SURDEX software was used to
visually inspect master tiles for seam and image defects.
SURDEX software was used to project and cut final DOQQ image
files from masters. SURDEX software was used to create CCM
metadata. Lizardtech GeoExpress version 8.0.0.3065 was used
to create the CCM image file. SURDEX software was
used to perform final formatting, QC and naming of the DOQQ.
USGS metadata parser software was used to validate the metadata.
Various versions of Microsoft Windows were used in all phases of
production. Grouping Tool was used again after DOQQ and CCM
production to provide a quality assurance check. Individual
DOQQ and CCM may not meet the USDA APFO Image Metrics ranges
due to land cover. The goal is to have the state as a
whole meet the Image Metrics. All products are reviewed
by independent personnel prior to delivery.
The delivery is checked for omissions, commissions,
naming, formatting, specification compliance and data integrity.
