This data set contains imagery from the National Agriculture Imagery Program
(NAIP). 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 60
centimeter ground sample distance (GSD) ortho imagery rectified to a horizontal
accuracy within +/- 4 meters of reference digital ortho quarter quads (DOQQ's) from
the National Digital Ortho Program (NDOP) or from the National Agriculture Imagery
Program (NAIP). The tiling format of NAIP imagery is based on a 3.75' x 3.75'
quarter quadrangle with a 300 pixel buffer on all four sides. The NAIP imagery is
formatted to the UTM coordinate system using the North American Datum of 1983
(NAD83). The NAIP imagery may contain as much as 10% cloud cover per tile. This file
was generated by compressing NAIP imagery that cover the county extent. Two types of
compression may be used for NAIP imagery: MrSID and JPEG 2000. The target value for
the compression ratio is 40:1 for imagery.
The NAIP imagery is typically 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 NAIP imagery is generally
acquired in projects covering full states in cooperation with state government and
other federal agencies who use the imagery for a variety of purposes including land
use planning and natural resource assessment. The NAIP is also used for disaster
response often providing the most current pre-event imagery.

None, The USDA-FSA Aerial Photography Field Office asks tobe credited in derived
products. If defects are found in the NAIP imagery during the 1 year warranty period
such as horizontal offsets, replacement imagery may be provided. Imagery containing
defects that require the acquisition of new imagery, such as excessive cloud cover,
specular reflectance, etc., will not be replaced within a NAIP project year.

Digital imagery was collected at a nominal GSD of 40cm using 10 Cessna
441’s, one Cessna 414, one Reims F406, three Piper PA31’s, one Piper PAY2 and
one Swearingen Merlin-3 aircraft flying at an average flight height of 8400m AGL
for the SH120 acquisition and 4400m AGL for SH100 acquisition. Aircraft flew
with Leica Geosystem's ADS100/SH100 digital sensors with firmware 4.57 or
ADS100/SH120 digital sensors with firmware 4.57. Each sensor collected 12 image
bands Red, Green, Blue and Near-infrared at each of three look angles; Backward
19 degrees, Forward 26 degrees and Nadir for the SH100. Backward 10 degrees,
Forward 14 degrees, and Nadir for the SH120. The Nadir Green band was collected
in high resolution mode effectively doubling the resolution for that band. The
ADS100 spectral ranges are; Red 619-651nm, Green 525-585nm, Blue 435-495nm and
Near-infrared at 808-882nm. The CCD arrays have a pixel size of 5.0 microns in a
20000x1 format at nadir; a 18000x1 format at the backward look angle and a
16000x1 format at the forward look angle. The CCD's have a dynamic range of 72db
and the A/D converters have a resolution of 14bits. The ADS is a push-broom
sensor the ground footprint of the imagery is approximately 8km wide at a
nominal 40cm GSD by the length flightline. The maximum flightline length is
limited to approximately 175km. The factory calibrations and IMU alignments for
each sensor (Serial Numbers: 10510, 10511, 10512, 10514, 10519, 10552, 10522,
10527, 10528, 10530, 10531, 10534, 10537, 10540, 10554, 12529) were tested and
verified by in-situ test flights before the start of the project. The Leica
MissionPro Flight Planning Software is used to develop the flight acquisition
plans. Flight acquisition sub blocks are designed first to define the GNSS base
station logistics, and to break the project up into manageable acquisition
units. The flight acquisition sub blocks are designed based on the specified
acquisition season, native UTM zone of the DOQQs, flight line length limitations
(to ensure sufficient performance of the IMU solution) as well as air traffic
restrictions in the area. Once the sub blocks have been delineated they are
brought into MissionPro for flight line design. The design parameters used in
MissionPro will be 30% lateral overlap and 40cm resolution. The flight lines
have been designed with a north/south orientation or east/west where required
for efficiency. The design takes into account the latitude of the state, which
affects line spacing due to convergence as well as the terrain. SRTM elevation
data is used in the MissionPro design to ensure the 50cm GSD is achieved over
all types of terrain. The raw data was downloaded from the sensors after each
flight using Leica XPro software. The imagery was then georeferenced using the
200Hz GPS/INS data creating an exterior orientation for each scan line
(x/y/z/o/p/k). Leica Xpro APM software was used to automatically generate
tiepoint measurements between the forward, nadir and backward look angles for
each line and to tie all flight lines together. The resulting point data and
exterior orientation data were used to perform a full bundle adjustment using
ORIMA software. Blunders were removed, and additional tie points measured in
weak areas to ensure a robust solution. Once the point data was clean and point
coverage was acceptable, photo-identifiable GPS-surveyed ground control points
were introduced into the block adjustment. The bundle adjustment process
produces revised exterior orientation data for the sensor with GPS/INS, datum,
and sensor calibration errors modeled and removed. Using the revised exterior
orientation from the bundle adjustment, orthorectified image strips were created
with Xpro software and the June 2018 USGS 10m NED DEM. The Xpro
orthorectification software applies an atmospheric-BRDF radiometric correction
to the imagery. This correction compensates for atmospheric absorption, solar
illumination angle and bi-directional reflectance. The orthorectified strips
were then overlaid with each other and the ground control to check accuracy.
Once the accuracy of the orthorectified image strips were validated the strips
were then imported into Inpho's OrthoVista 7.1.2 package which was used for the
final radiometric balance, mosaic, and DOQQ sheet creation. The final DOQQ
sheets, with a 300m buffer and a ground pixel resolution of 60cm were then
combined and compressed to create the county wide CCMs.
