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.

NAIP horizontal accuracy specifications have evolved over
the life of the program. From 2003 to 2004 the
specifications were as follows: 1-meter GSD imagery was
to match within 3-meters, and 2-meter GSD to match within 10
meters of reference imagery. For 2005 the 1-meter GSD
specification was changed to 5 meters matching the reference
imagery. In 2006 a pilot project was performed using true
ground specifications rather than reference imagery. All
states used the same specifications as 2005 except Utah,
which required a match of +/- 6 meters to true ground.
In 2007 all specifications were the same as 2006 except
Arizona used true ground specifications and all other states
used reference imagery. In 2008 and subsequent years
no 2-meter GSD imagery was acquired and all specifications
were the same as 2007 except approximately half of the
states acquired used true ground specifications and the
other half used reference imagery. The 2008 states that
used absolute ground control where; Indiana, Minnesota,
New Hampshire, North Carolina, Texas, Vermont, and Virginia.
From 2009 to present all NAIP imagery acquisitions used
the +/- 6 meters to ground specification.

Aerial Photography Date for aerial photo source.
Georectifed Image
Digital Georectifed Image.
Aerial photography acquired from April 24, 2010 until
September 30, 2010. Aerial photography was acquired
using a frame based digital camera (UltraCamD (UCD),
UltraCamX (UCX), or DMC), therefore no scanning conversion
from film to digital was needed. Geometric and radiometric
calibration for each one of the camera heads is determined
in the manufacturing laboratory. This step is also
known as geometric and radiometric calibration of a
single camera head and done when the sensor is being
manufactured. The 4 multispectral heads collect 4
separated bands: Red, Green, Blue and Near Infrared
wavelength. Both the UltraCam and DMC sensors collect
12bit data. The UCD sensor CCD pixel size is 9 micron
with a footprint of 7500 pixels in the long track, and
11500 pixels in the cross track. The UCX sensor CCD pixel
size is 7.2 micron with a footprint of 9420 pixels in the
long track, and 14430 pixels in the cross track. The
DMC sensor CCD pixel size is 12 micron with a footprint
of 7680 pixels in the long track, and 13824 pixels in
the cross track. Twin Engine Navajo and Malibu, Turbo
Commander and Cessna 320 and Cessna Conquest aircraft
were used, flying at average flight height of 6,500
to 8,500 meters above ground, allowing image acquisition
of 0.40 to 0.67 meters Ground Sample Distance. An INS -
Inertial Navigation System, with AGPS (Airborne GPS) and
IMU (Inertial Measurement Unit) was utilized for all
aerial missions. The INS allows for accurate photo-center
registration and image orientation. For inspection and
verification of accuracy of the exterior orientation
computed with the Inertial Navigation System, stereo
compilation was performed for every flight mission and
its result compared against higher accuracy source data.
If a test of positional accuracy failed (> 5 meters) a
full analytical triangulation is processed for that
mission, assuring accurate horizontal positioning.
USGS seamless NED data was used as a surface for
ortho-rectification. Sanborn used proprietary software
called METRO to rectify the scanned images. Rectification
was done using cubic convolution resampling. Color
balancing was then performed on each exposure. Sanborns
software tonally balanced each exposure to alleviate the
effects of hotspots, side-to-side shading within an
exposure, and tonal differences between flightlines
due to dissimilar conditions at the time of capture.
Each exposure was then balanced to predefined target
values used throughout the project, creating a dataset
consistent and uniform in radiometry. Seams between
exposures were determined by Sanborns software to use
the best exposure based on proximity to nadir and ground
angle to the camera. Delivery tiles were then extracted
from Sanborns seamlessimagery database, named to meet the
DOQQ and/or DOQ naming convention, and formatted as defined
in the task order. Horizontal accuracy was once again tested
for 6-meter absolute accuracy. If necessary, a new
aerotriangulation adjustment would be performed for the
affected flight mission and new set of doqqs produced.
Quality control was performed on a sampling of each
deliverable to ensure no artifacts or anomalies were
present in the imagery. Satellite imagery was also
used to supplement aerial imagery to complete up to 12
DOQQ tiles for which suitable airborne imagery was
unavailable. The supplemental satellite imager was
acquired using GeoEye-1. GeoEye-1 scenes were acquired
from GeoEye. Sensor model and orientations were supplied.
The raw data has a sub-meter pixel resolution and provided
in 4 bands: Red, Green, Blue and Near Infrared wavelength.
USGS seamless 2009 NED (National Elevation Data) was used
as surface for ortho-rectification. Sanborn utilized
commercial software called OrthoPRO, form Z/I Intergraph,
to ortho-rectify the digital satellite images. The rectified
images were then integrated into Sanborn proprietary
software called METRO. The final production processes
then followed the same procedures as described above
for the aerial photography.
