    <descript>
      <abstract>Color infrared aerial photography was collected, in stereo with 60 percent forward overlap and 40 percent side overlap on 7-14-02.  The flight height was 20,000 feet above mean terrain.  Airborne GPS data were collected.  The original film was scanned at 14 microns to create pixels of approximately .56 meters.  New elevation data were collected with auto-correlated software, edited, and supplimented with breaklines and spot elevation points collected on a softcopy stereo plotter using ATLAS software.  The elevation data were used to create digital orthophotos.</abstract>
      <purpose>The aerial photography and orthophotos will be used for scientific research.</purpose>

    <attracc>
      <attraccr>Orthophotos were created from the aerial photography using new elevation data and aero triangulation data.  The X, Y, Z, omega, phi, and kappa for each photograph were calculated by Horizons, Inc.  Airborne GPS data were collected during the photography mission for each exposure station. The GPS event is at the photo-center of each exposure.  The final adjustment of this block was solved using Erio Technologies ALBANY software. ALBANY is a simultaneous least squares bundle adjustment, which is designed for use with airborne GPS.</attraccr>

        <procdesc>Scanner: Intergraph PhotoScan TD Photo Digitizing System.
Scanner Geometric Calibration:
Standard Deviation (sigma) = 1.6710356970
Root Mean Square X = 1.9970393211
Root Mean Square Y = 0.9624905604
Scanner setting:
Transmissivity: 0.0151 0.6610
Film Density: 1.8210 0.1778
Gamma: 1.75
Quality Control Procedures:
Film was kept in airtight containers prior to scanning.  Both the base and emulsion sides of the film were cleaned using a tacky roller system prior to scanning. Color adjustment was achieved by visually matching the tone, contrast, and brightness to the original film. Each scanned image was checked computationally for missing data.
Quality Control Procedures for orthophoto production:
After individual orthophotos were mosaiced into a regional database, the resulting orthophoto composite was visually inspected for tone balance and image distortion.  In areas of image distortion, more suitable orthophoto imagery was inserted, when possible.  The final orthophotos were visually inspected for accuracy and consistency.</procdesc>
