  Description:
    Abstract:
      A major advantage of remotely sensed satellite images is the
      regional/synoptic view of the data. The regional perspective view is
      enhanced further by digitally mosaicking different images collected
      by the same satellite to cover an even larger regional area. Another
      advantage is the multitemporal aspect of satellite images, which can
      be used to monitor changes on the Earth's surface or update an
      existing data set. In this particular case an existing digital AVHRR
      satellite image mosaic was updated with newer and better images to
      replace cloud covered areas, and digital image processing
      techniques were used to improve the presentation of the data. The
      United States Geological Survey's (USGS) Mini Image Processing
      System (MIPS) was used to apply the geometric, radiometric, and
      spatial filtering required to update and improve the existing digital
      mosaic, as well as the merging of AVHRR and topographic images.
      The digital image map results were published in hardcopy format
      as USGS Miscellaneous Investigation Series Map I-2560. The hardcopy
      image map scale is 1:5,000,000 with selected geographic
      names and contours printed on the image base. The image map was
      prepared by the USGS with joint support from the National Science
      Foundation Interagency Agreement OPP-9114787.

    Purpose:
      to create and print a continental image map of Antarctica
      and create an image product useful for a variety of
      Antarctic research areas

    Supplemental_Information: This data set contains 3 images: 1 rasterized DEM, and 2 bands AVHRR mosaics.

  Data_Set_Credit:
    The Antarctica digital elevation model (DEM) was acquired
    from a USGS EROS Data Center world wide web page, and are
    part of the global GTOPO30 data available from the EDC.
    The DEM data, like the AVHRR mosaic, are in a polar
    stereographic projection with 1 km resolution and only
    simple scaling and translation were used to geometrically
    register the two images. The documentation supplied with the
    DEMs state that they were generated from contour and coastline
    data made available by the Antarctic Digital Database (ADD),
    which was produced under the guidance of the Scientific
    Committee on Antarctic Research (SCAR). These data were then
    used as input to the Australian National University Digital
    Elevation Model (ANUDEM) computer program developed by Michael
    Hutchinson. The digital image mosaic used as input was previously
    mosaicked, controlled, and geometrically corrected into a Polar
    Stereographic projection by the National Remote Sensing Center,
    United Kingdom. The image map was prepared by the USGS with joint
    support from the National Science Foundation Interagency Agreement
    OPP-9114787.

Data_Quality_Information:
  Logical_Consistency_Report:
    The digital image mosaic used as input was previously mosaicked, controlled, and geometrically corrected
    into a Polar Stereographic projection by the National Remote Sensing Center, United Kingdom. Details of
    the processing they used to generate the original mosaic can be found in the International Journal of
    Remote Sensing (1989, v. 10, nos. 4 and 5, p. 669-674). The USGS evaluated the geometric accuracy of
    the mosaic and estimated a root-mean-square error of 2.5 km. The digital image processing that created
    this modified image base was done at the USGS Flagstaff Field Center, Flagstaff, Arizona. Replacement
    images were geometrically corrected to the first image base, digitally inserted into the mosaic, and
    radiometrically/tone matched to blend with the surrounding images. The image coverage diagram showing
    the mosiac segments, acquisition date and time, and satellite source is found on the web at
