Shoreline Definition of Inland Water Bodies Not Hydrologically Connected to the Ocean
Most airborne topographic light detection and ranging (lidar) systems operate within the near-infrared spectrum. Laser pulses from these systems frequently are absorbed by water and do not generate reflected returns on water bodies in the resulting lidar point cloud. Thus, the absence of lidar returns over water is useful for identifying inland water bodies that are not connected by any path to...
Shoreline Definition in Emergent Wetland Environments
Coastal shoreline mapping is a particularly complex issue because of the dynamic nature of water levels at the land-water interface, the various tidal vertical datums in use, and the spatial scale of the shoreline delineation. In addition, the definition of a shoreline varies depending on whether the shoreline will be used for nautical charts and navigation, delineating the legal federal and state...
Structure From Motion
Coastal topographic and bathymetric (topobathymetric) data with high spatial resolution (1-meter or better) and high vertical accuracy are needed to assess the vulnerability of Pacific Islands to climate change impacts, including sea-level rise. According to the Intergovernmental Panel on Climate Change reports, low-lying atolls in the Pacific Ocean are extremely vulnerable to king tide events...
Storm Surge Hazards
The USGS Coastal National Elevation Database Applications Project organized a workshop in cooperation with the College of Staten Island-City University of New York to discuss storm surge modeling and get input from scientists across a broad community. The workshop, held on April 22-23, 2014 on the College of Staten Island campus, is part of a larger project intended to enhance topobathymetric...
Sea-level rise
The accuracy with which coastal topography has been mapped directly affects the reliability and usefulness of elevation-based sea-level rise vulnerability assessments. Recent research has shown that the qualities of the elevation data must be well understood to properly model potential impacts. The cumulative vertical uncertainty has contributions from elevation data error, water level data...
Restoration, Redevelopment, and Protection Projects
The Coastal National Elevation Database Applications Project supports scientific research and applications assessing restoration, redevelopment, and protection projects in the Hurricane Sandy impact areas along New Jersey and New York coastal beaches.
Coastal Multi-Temporal Elevation Database
The U.S. Geological Survey (USGS) National Geospatial Program's 3D Elevation Program (3DEP) aims to collect new light detection and ranging (lidar) data over the same areas on an 8-year return cycle. Between lidar surveys, there may be significant differences in bare- and non-bare earth heights due to both natural and human-induced geomorphic changes that occur. Therefore, research methods are...
Coastal Landscape Change and Vulnerability
Scientific research and applications assessing coastal landscape change and vulnerability are critical for applications such as shoreline mapping, hydrodynamic modeling, coastal vulnerability, and coastal geomorphology studies. However, very little ground truth data are available within the intertidal zone and adjacent beaches.
Satellite-Derived Bathymetry
Defining near-shore water depth (bathymetry) is problematic because ships cannot operate close to the shore while collecting acoustic bathymetric soundings. Alternatively, optical green laser lidar sensors have been used to collect bathymetric points, however, these types of lidar acquisitions are costly for the footprint collected and are subject to bathymetric inaccuracies in turbid water...
River bathymetry
This image is a topobathymetric elevation model of a part of the Mississippi River in New Orleans, Louisiana, and is an example of inland bathymetry in the northern Gulf of Mexico. This regional topobathymetric elevation model includes airborne light detection and ranging (lidar) point clouds, hydrographic surveys, side-scan sonar surveys, and multibeam surveys obtained from USGS, NOAA, the State...
Levee Crest Elevation Profiles
This study explores the feasibility of using high-resolution digital elevation models (DEMs) constructed from airborne light detection and ranging (lidar) surveys to develop an automated procedure to extract levee longitudinal elevation profiles for both federal levees in Atchafalaya Basin and local levees in Lafourche Parish, south Louisiana. This approach can successfully accommodate abrupt...
Coastal Economic Vulnerability Index
The northern Gulf of Mexico 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...
