Coastal Economic Vulnerability Index
The northern Gulf of America coast of the United States has been identified as highly vulnerable to sea-level rise (SLR), based on a combination of physical and societal factors. Vulnerability of human populations and infrastructure to projected increases in sea level is a critical area of uncertainty for communities in the extremely low-lying and flat northern gulf coastal zone. A rapidly growing...
Cliff Metric Development and Analysis
Seacliff erosion is a serious hazard with implications for coastal management, infrastructure, and residential dwellings; seacliff erosion is often estimated using successive hand digitized cliff tops or bases to assess cliff retreat. Traditionally the recession of the cliff top or cliff base is obtained from aerial photographs, topographic maps, or in situ surveys. The availability of high...
Delineation of Water Bodies In Emergent Wetlands
The Coastal National Elevation Database (CoNED) Applications Project team has developed new applications for pre- and post-Hurricane Sandy regional light detection and ranging (lidar) datasets for mapping the spatial extent of coastal wetlands. These new methods were developed to derive detailed land/water polygons for an area in coastal New Jersey, which is dominated by a complex configuration of...
Hurricane Sandy Region - Topobathymetric Elevation Model of Chesapeake Bay
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...
Mapping Fluvial Ecosystems
Light detection and ranging (lidar) wave-form processing capabilities are being developed to utilize the U.S. Geological Survey Coastal and Marine Geology Program Experimental Advanced Airborne Research (EAARL) sensor. The EAARL lidar point cloud collection consists of highly detailed submerged and shallow bathymetry (water depth) of river channels, which will be merged with land elevation...
Coastal National Elevation Database (CoNED) Applications Project
High-resolution coastal elevation data is required to identify flood, hurricane, and sea-level rise inundation hazard zones and other earth science applications, such as the development of sediment transport and storm surge models. Light detection and ranging (lidar) enables the rapid collection of very accurate elevation data over large areas, and during the last decade, airborne laser altimetry...
