Combined High-Resolution Topography and Bathymetry for Western Passage Canal, Near Whittier, Alaska

This dataset is a new Digital Elevation Model (DEM) using the best available high-resolution topography and bathymetry surrounding the area of Whittier, Alaska. We utilized three datasets (1) LiDAR topography collected by the Alaska Division of Geological and Geophysical Surveys (DGGS) in 2012, (2) multibeam echosounder system (MBES) survey of western Passage Canal collected by the USGS in the summer of 2011 (3) and NOAA single-beam soundings collected from September 26-October 18, 1995.
