PE&RS January 2005VOLUME 71, NUMBER 1PHOTOGRAMMETRIC ENGINEERING & REMOTE SENSING JOURNAL OF THE AMERICAN SOCIETY FOR PHOTOGRAMMETRY AND REMOTE SENSING
The cover image of Mount St. Helens is a bare-Earth lidar digital elevation model, acquired September 20 – 22, 2003. Four quarter quad tiles of bare-Earth lidar TINs, which comprised the edifice of Mount St. Helens, were converted to 3-meter resolution lattices’ with ESRI ArcInfo. These the four separate lattice tiles were merged to create one continuous floating point grid. A color ramp was designed to accentuate the edifice topography and applied to the floating point grid with a black and white hillshade grid applied on top of the colorized grid at 40% transparency. The lidar data was collected by Earth Data International, LLC in support of U.S. Geological Survey’s (USGS) High Priority Data Collection for the Department of the Interior. The lidar was flown at an altitude of 2438 meters (8000 feet) above mean terrain (AMT), with 3-meter postings, and an average swath width of 1537 meters. The lidar dataset of Mount St Helens is available to the public through The National Map http://nationalmap.usgs.gov/, and National Elevation Dataset http://seamless.usgs.gov/. Vivian R. Queija, Geographer for the U.S. Geological Survey prepared the lidar image and design. For more information on this image and data availability, please contact 1 -888-Ask-USGS (1888-285-8747) or email ask@usgs.gov.
