Abstract:
This data set contains a modified version of imagery from the 
National Agriculture Imagery Program (NAIP). The original 
APFO orthoimagery has been modified  by the Arizona State 
Land Department ALRIS Program. The APFO TIFF quarterquads 
were mosaiked into 1/2 degree blocks (ALRIS Tiles), compressed
(1:20) and reformatted as SID/SDW files. Tiles that were in 
UTM NAD83 Zone 11 were also reprojected into UTM NAD83 Zone 12. 
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.
Purpose:
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 GSD product
provides an ortho image base for Common Land Unit boundaries and
other data sets.  The 1 meter 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.  With an annual cycle, NAIP is also used
for disaster response often providing the most current pre-event imagery.

Use_Constraints:
Imagery may be replaced to address defects found in a
small number of products through quality assurance
processes.  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.

Process_Step:
Process_Description:
Imagery was flown with Leica ADS40 digital sensors to
capture 0.9m raw data.  Raw data was then downloaded
using Leica GPro software into 12 bit TIFF format.
The raw TIFF imagery was then georeferenced and
reprojected using GPS/INS 200Hz exterior orientation
information (x/y/z/o/p/k).  Technicians precisely
measured ground control and tie points in 3 bands/looks
(Back/Nadir/Forward) for each line. The resulting point
data, ground control, and orientation data was used to
perform a full bundle adjustment.  Any blunders were
removed, and weak areas were manually supplemented to
ensure good coverage of points.  Once the point data
was cleaned, and point coverage was acceptable, control
points from the prior generation MDOQQ's and source
DEM were introduced in the corners and center of the
block being adjusted. This control was used to perform
any datum shift (x/y/z and rotation) to ensure the new
adjusted imagery fitted the existing MDOQQ reference
imagery.  The output from this bundle adjustment
process was revised exterior orientation data for the
sensor with any GPS/INS, datum, and sensor calibration
errors modeled and compensated for.  Using this revised
EO data orthorectified image strips were created using
the USGS DEM.  The 10m DEM was used where available and
30m DEM was used elsewhere.  The orthorectified strips
were overlaid with the existing MDOQQ compressed files
to ensure accuracy was met by visual inspection and
manually measuring features.  Once the accuracy of the
orthorectified image strips were validated the strips
were processed with a NWG proprietary dodging package
that compensates for the bi-directional reflectance
function that is caused by the sun's position relative
to the image area.  This compensated imagery was then
imported into Inpho's OrthoVista 4.0 package which was
used for the final radiometric balance, mosaic, and
DOQQ sheet creation.

Process_Step:
Process_Description:
The following processes were carried out with LizardTech GeoExpress 
software ( v.7): DOQQ TIFF files were mosaiked to conform to the ALRIS tile index 
structure (half-degree blocks). The mosaiked tiles were also buffered (2-4 miles) 
on all four sides where permissible. Some files were also reprojected from 
UTM NAD83 Zone 11 into UTM NAD83 Zone 12. Each mosaic was then 
compressed (1:20) and saved in a SID format (with accompanying SDW files).
