Data

The U.S. Geological Survey (USGS) Coastal National Elevation Database Applications (CoNED) Project Viewer contains integrated topobathymetric data (topobathy) of merged renderings of both topography (land elevation) and bathymetry (water depth).

One Meter Topobathymetric Digital Elevation Model for Lake Powell, Arizona-Utah, 1947-2018

To support the modeling of the Colorado River water storage area capacity tables by the U.S. Geological Survey (USGS) Utah Water Science Center in the Glen Canyon National Recreation Area in Utah and Arizona, the USGS Earth Resources Observation and Science (EROS) Center has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for Lake Powell, the second largest man-made r

Topobathymetric Model for the Southern Coast of California and the Channel Islands, 1930 to 2014

To support the modeling of storm-induced flooding, the USGS Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for the Southern California Coast and Channel Islands. The Channel Islands are a chain of eight islands where years of isolation has created unique fauna, flora, and archeological resources. Th

Topobathymetric Model for the Central Coast of California, 1929 to 2017

To support the modeling of storm-induced flooding, the USGS Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for the Central California Coast. High-resolution coastal elevation data is required to identify flood, hurricane, and sea-level rise inundation hazard zones and other earth science application

One Meter Topobathymetric Digital Elevation Model for Majuro Atoll, Republic of the Marshall Islands, 1944 to 2016

Located in the western Pacific Ocean, Majuro is a large coral atoll consisting of a large, central narrow land mass and remote islands that are part of the Republic of the Marshall Islands. The waters surrounding the Majuro Atoll land areas are relatively shallow with poorly mapped bathymetry. However, the Pacific Ocean on the exterior of the coral atoll and the lagoon within its interior consist
