A digital elevation model (DEM) was produced from swath interferometric, multibeam bathymetry, and lidar at 30-meter resolution

Figure 3. A digital elevation model (DEM) was produced from swath interferometric, multibeam bathymetry, and lidar at 30-meter resolution (table 1). High rugosity and high relief are most often associated with rocky areas, whereas smooth, low relief regions tend to be blanketed by fine-grained sediment deposits.  NAVD 88, North American Vertical Datum of 1988.
