A comparison of Landsat 8 Operational Land Imager and Provisional Aquatic Reflectance science product, Sentinel–2B, and WorldView–3 imagery for empirical satellite-derived bathymetry, Unalakleet, Alaska
Satellite-derived bathymetry (SDB) based upon an empirical band ratio method is a cost-effective means for mapping nearshore bathymetry in coastal areas vulnerable to natural hazards. This is particularly important for the low-lying coastal community of Unalakleet, Alaska, that has been negatively affected not only by flooding, storm surge, and historically strong storms but also by high erosion r
Inundation exposure assessment for Majuro Atoll, Republic of the Marshall Islands using a high-accuracy digital elevation model
Majuro Atoll in the central Pacific has high coastal vulnerability due to low-lying islands, rising sea level, high wave events, eroding shorelines, a dense population center, and limited freshwater resources. Land elevation is the primary geophysical variable that determines exposure to inundation in coastal settings. Accordingly, coastal elevation data (with accuracy information) are critical fo
Coastal National Elevation Database
The Coastal National Elevation Database (CoNED) Applications Project develops enhanced topographic (land elevation) and bathymetric (water depth) datasets that serve as valuable resources for coastal hazards research (Danielson and others, 2016; Thatcher and others, 2016). These datasets are used widely for mapping inundation zones from riverine flood events, hurricanes, and sea-level rise and for

Alaska North Slope LiDAR
High-resolution light detection and ranging (lidar) elevation data were acquired along the north coast of Alaska between 2009 and 2012. The lidar acquisition, from Icy Cape, Alaska to the United States/Canadian border, comprised approximately 11,000 km 2 . The airborne lidar data were acquired in support of the U.S. Geological Survey Coastal and Marine Geology Program. The purpose of this lidar...
3D Topobathymetric Digital Elevation Model for Lake Powell Storage Capacity Assessment
To support the modeling of the Colorado River water storage area capacity tables by the U.S. Geological Survey (USGS) Utah Water Science Center, the USGS Earth Resources Observation and Science (EROS) Center created a 3D high-resolution topobathymetric digital elevation model (TBDEM) for Lake Powell. Located in south-central Utah and north-central Arizona, the second largest man-made reservoir in...
Southern California / Channel Islands - Topobathymetric Elevation Model of the Channel Islands
Located in the Pacific Ocean off the coast of California, the Channel Islands are a chain of eight islands where years of isolation has created unique fauna, flora, and archeological resources. Five of the islands are part of Channel Islands National Park (Anacapa, Santa Cruz, Santa Rosa, San Miguel, and Santa Barbara), and the waters surrounding these islands make up the Channel Islands National...
