      Title: Clifflines
      Publication_Date: 2012
      Originator: Guam Coastal Management Plan, Bureau of Statistics and Plans
  Description:
    Abstract: This dataset was originally developed for the purpose of the tsunami evacuation maps and later extended to include all major clifflines on Guam. The lines were digitized on-screen at a scale of about 1:15,000 based on visual interpretation of LiDAR-derived hillshade and slope raster. Cliffs are taken to generally have a slope greater than 60 degrees. The lines only show the approximate extent of the clifflines.
    Purpose: To show the extent of major clifflines on Guam.
    Supplemental_Information: Cliffs are taken to generally have a slope greater than 60 degrees. The location is approximate, line is simplified.

      Process_Description: Clifflines were extended to include all major clifflines on Guam for the purpose of including it in the Natural Resource Atlas of Northern Guam. The lines were digitized on-screen at a scale of about 1:15,000 based on visual interpretation of LiDAR-derived hillshade and slope raster.
