Topobathymetric Elevation Models

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...

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...

Accurate, high-resolution elevation information is vital to understanding the natural hazards that can impact the highly populated San Francisco Bay area, such as sea-level rise, winter storms, cliff erosion, and other coastal hazards. The San Francisco Bay estuary three-dimensional (3D) topobathymetric digital elevation model (TBDEM) was developed in collaboration between U.S. Geological Survey...

Pamlico Sound is ecologically important as it is the second largest estuary in the United States, and is the largest lagoon on the U.S. east coast. The sound is separated from the Atlantic Ocean by the Outer Banks, a series of low, sandy barrier islands that are vulnerable to hurricane storm surge and sea-level rise. The seamless high-resolution topobathymetric digital elevation model (TBDEM) for...

Accurate, high-resolution elevation information is vital to understanding the highly dynamic northern Gulf of Mexico coast, the location of North America’s largest delta system and the focus of one of the largest coastal restoration and flood risk reduction efforts in the United States. The northern Gulf of Mexico topobathymetric digital elevation model (TBDEM) was developed in collaboration...

With an estimated elevation of only 3-meters above sea level, the Majuro Atoll, capital of the Republic of the Marshall Islands (RMI), is extremely vulnerable to sea-level rise, tsunamis, storm surge, and coastal flooding that could impact the sustainability of the infrastructure, groundwater, and ecosystems. Located in the northern tropical Pacific Ocean, the waters surrounding the Majuro Atoll...

Mobile Bay is ecologically important as it is the fourth largest estuary in the United States. The Mobile Bay topobathymetric digital elevation model (TBDEM) was developed in collaboration between U.S. Geological Survey (USGS) Coastal and Marine Geology Program (CMGP) and USGS National Geospatial Program (NGP) using a combination of 71 disparate topographic and bathymetric datasets collected from...

Hurricane Sandy severely impacted the New Jersey/Delaware coast, altering the topography and ecosystems of this heavily populated region. In response to the storm, the U.S. Geological Survey (USGS) Coastal and Marine Geology Program in collaboration with USGS National Geospatial Program , and National Oceanic and Atmospheric Administration developed three-dimensional (3D) topobathymetric elevation...

Hurricane Sandy had significant impacts throughout the Chesapeake Bay, altering the topography and ecosystems of this populous coastal region. In response to the storm, the U.S. Geological Survey (USGS) Coastal and Marine Geology Program in collaboration with USGS National Geospatial Program, and National Oceanic and Atmospheric Administration developed three-dimensional (3D) topobathymetric...
