Geological Survey, FISC St. Petersburg Publication_Date: July 2007 Title: EAARL Topography-Assateague Island National Seashore-Hillshade Geospatial_Data_Presentation_Form: raster digital data Description: Abstract: A hillshade generated from a LiDAR GeoTIFF. Purpose: This hillshade is used to enhance the visual appearance of a LiDAR tile by providing three-dimensional relief. Supplemental_Information: See the source LiDAR GeoTIFF tile for more specific accuracy information.
