Coastal digital elevation models (DEMs) help researchers and decision makers understand and predict environmental changes that affect coastal regions. DEM data is used in a wide range of critical monitoring activities, including coastal process modeling (tsunami inundation, storm surge, sea-level rise, contaminant dispersal, etc.), ecosystem management, habitat research, coastal and marine spatial planning, hazard mitigation, and community preparedness.
