Abstract: This data set contains digital ortho-imagery developed to support planning and delivery of USDA programs. The USDA field service centers use digital ortho imagery as a basic reference for conservation plans and soil survey. The imagery has a 1 meter ground sample distance (GSD) ortho imagery rectified to National Mapping Standards at the 1:24,000 scale. Imagery is based on a (7.5 x 15) or (7.5 x11.25) minute quarter quadrangle with a 300 meter buffer on all four sides. Quarter quads imagery is formatted to the UTM coordinate system using NAD83. Each quad may contain as much as 10% cloud cover per tile. This file was generated by compressing quarter quadrangle tiles that cover a project area. MrSID compression, with mosaic option, was used. Target values for the compression ratio are (15:1) and compression levels (9) are used.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Description:
Abstract:
This data set contains digital ortho-imagery developed to support
planning and delivery of USDA programs. The USDA field service centers
use digital ortho imagery as a basic reference for conservation plans
and soil survey. The imagery has a 1 meter ground sample distance (GSD)
ortho imagery rectified to National Mapping Standards at the 1:24,000
scale.  Imagery is based on a (7.5 x 15) or (7.5 x11.25) minute quarter
quadrangle with a 300 meter buffer on all four sides. Quarter quads
imagery is formatted to the UTM coordinate system using NAD83. Each
quad may contain as much as 10% cloud cover per tile. This file was
generated by compressing quarter quadrangle tiles that cover a project
area.  MrSID compression, with mosaic option, was used. Target values
for the compression ratio are (15:1) and compression levels (9) are
used.

Purpose:
Imagery is used to meet USDA program requirements including conservation
planning and soil survey.  The interim product is a compressed
mosaic.  Users should be aware that the interim compressed mosaic may
contain defects and have horizontal accuracy less than the specified
tolerances.

Process step:
Process description:
Imagery was flown with Leica ADS40 digital sensors to capture 0.9m
raw data.  Raw data is then downloaded using Leica GPro software into
12 bit TIFF format.  The raw TIFF imagery is then georeferenced and
reprojected using GPS/INS 200Hz exterior orientation information
(x/y/z/o/p/k) to allow stereo viewable imagery.  This stereo viewable
imagery is processed with the GPro/LPS automatic point matching
algorithm to determine common match points every 2000 pixels across
the imagery strip and 333 pixels along strip. This pattern includes
dual rows of line ties to the adjacent line of imagery.  The
resulting point data is imported in Leica ORIMA and used to perform
a full bundle adjustment of the imagery point data.  Any blunders
are removed, and weak areas are manually supplemented to ensure
good coverage of points.  Once the point data is cleaned and point
coverage is acceptable vertical control points from the prior
generation MDOQQ's are introduced in the corners and center of the
block being adjusted.  This control is used to perform any datum
shift (x/y/z and rotation) to ensure the new adjusted imagery fits
the existing MDOQQ reference imagery.  The output from this bundle
adjustment process is 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 are created using the USGS DEM.  The
10m DEM is used where available and 30m DEM is used elsewhere.  The
orthorectified strips are overlaid over the existing MDOQQ
compressed files to ensure accuracy is met by a visual inspection
and manually measuring features.  Once the accuracy of the
orthorectified image strips are validated the strips are 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 is
then imported into Inpho's OrthoVista 4.0 package which is used for
the final radiometric balance, mosaic, and DOQQ sheet creation.
These final DOQQ sheets contain a 300m minimum buffer.  These final
DOQQ tiles are edge inspected to the existing MDOQQ sheets for
accuracy validation.  The final DOQQ tiles are then organized into
directories based on the USDA provided county lists.  A visual
inspection is performed of the entire county to ensure all tiles
are present and the radiometric quality of the county looks good.
If the radiometric quality is acceptable the county is compressed
to MG3 format using Lizard Tech's GeoExpress v5.0 with a compression factor of 15
and 9 overview levels.  Once this compression is complete manual
reviewing is performed to ensure satisfactory results.  The
associated CCM shapefile is created using ESRI ArcView 9.0 with the
latest service packs.
