    Description:
      Abstract:
        This data set contains imagery from the National Agriculture
        Imagery Program (NAIP).  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
        of ortho imagery within one year of acquisition. NAIP provides
        four main products: 1 meter ground sample distance (GSD) ortho
        imagery rectified to a horizontal accuracy of within +/- 5
        meters of reference digital ortho quarter quads (DOQQ's) from
        the National Digital Ortho Program (NDOP); 2 meter GSD
        ortho imagery rectified to within +/- 10 meters of reference
        DOQQs; 1 meter GSD ortho imagery rectified to within +/- 6
        meters to true ground; and, 2 meter GSD ortho imagery rectified
        to within +/- 10 meters to true ground.  The tiling format of
        NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle
        with a 300 meter buffer on all four sides.  NAIP quarter quads
        are formatted to the UTM coordinate system using NAD83.  NAIP
        imagery may contain as much as 10% cloud cover per tile.
      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.  While suitable for a variety of uses the 2 meter
        GSD NAIP imagery is primarily intended to assess crop condition
        and compliance to USDA farm program conditions.  The 2
        meter imagery is generally acquired only for agricultural areas
        within state projects.

    Access_Constraints: There are no limitations for access.
    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:
          Color positive film (Kodak 2427) is scanned using Z/I
          PhotoScan photogrammetric quality scanning machines
          at a resolution of 21 microns. The scanned digital
          imagery is used in the Aerial Triangulation (AT)
          process in preparation for ortho-rectification. The
          horizontal accuracy of the orthorectified imagery is
          primarily determined by the quality of the AT
          solution and the surface model (digital elevation
          model or DEM). The AT process is initiated with the
          population of Z/I project files with ABGPS and
          horizontal control picked from USDA furnished
          mosaicked DOQQs (mDOQQs) and vertical control picked
          from the USGS DTED 2 DEM data. Images are tied together
          using Z/I ISAT automatic image correlation software
          with supplemental manually read points using Z/I ISDM
          software. Upon completion of mensuration, a preliminary
          adjustment is run to check for image blunders and poor
          image ties using PATB-NT software. Tie points are
          corrected or added, ground control is measured and the
          adjustment is run with ABGPS data and ground control.
          Withholding select ground control points performs
          quality control of the adjustment. AT is finalized by
          densifying the control and generating relative and
          absolute orientations (RO and AO) for each frame of
          photography. Orthorectifications are performed on the
          core portion of each image to minimize the radial
          horizontal displacement away from the photocenter.
          Each DOQQ is inspected for relative horizontal
          accuracy with adjacent DOQQ tiles. A sample of DOQQs
          is inspected for relative horizontal accuracy with
          the USDA furnished mDOQQs. Completed and approved DOQQs
          are assembled into a countywide MrSID file, using a
          compression factor of 1:50.
