Collecting Elevation Data to Understand Climate Change Effects in the Marshall Islands
The Intergovernmental Panel on Climate Change reports that low-lying atolls (ring-shaped islands or island chains made of coral) in the Pacific Ocean are extremely vulnerable to high tide events (“king tides”), storm surge, tsunamis, and sea-level rise. The Republic of the Marshall Islands (RMI) spreads over 29 atolls and has a population of over 50,000 people with homes and communities...
Simulating and Projecting Future Impacts of Sea Level Rise on Majuro Atoll
The Republic of the Marshall Islands (RMI) spreads over 29 atolls and has a population of over 50,000 people; over 27,000 of those people live on the Majuro Atoll, RMI’s capital. Sea level rise threatens the very existence of RMI as high-end projections of sea level rise by the end of the century exceed the average elevation of these low atoll reef islands. Already, waves wash over...
Evaluating Sea-level Rise Impacts in the Northeastern U.S.
In 2010, 39 percent of the U.S.population lived near the coast. This population is expected to increase by 8 percent from 2010 to 2020. Coastal regions are also home to species and habitats that provide critical services to humans, such as wetlands that buffer coasts from storms. Therefore, sea-level rise and the associated changes in coastlines challenge both human communities and...

Vertical Land Change in Select Counties of Kentucky, Minnesota, and Wisconsin Vertical Land Change in Select Counties of Kentucky, Minnesota, and Wisconsin
The Vertical Land Change project is an assessment of the impacts of surface mining in Perry County, Kentucky, the Mesabi Iron Range in northeastern Minnesota, and the west central part of Wisconsin. This project builds and expands upon previous vertical land change efforts (Gesch, 2006) by conducting research into the issues surrounding the integration of 3D data products with 2D remote...
Delineation of Water Bodies in Emergent Wetlands in Coastal New Jersey Delineation of Water Bodies in Emergent Wetlands in Coastal New Jersey
Hurricane Sandy, which made landfall on October 29, 2012, near Brigantine, New Jersey, had a significant impact on coastal New Jersey, including the large areas of emergent wetlands at Edwin B. Forsythe National Wildlife Refuge (NWR) and the Barnegat Bay region. In response to Hurricane Sandy, U.S. Geological Survey (USGS) has developed new applications for pre- and post-Hurricane Sandy...
Coastal Landscape Response to Sea-Level Rise Assessment for the Northeastern United States Data Release Coastal Landscape Response to Sea-Level Rise Assessment for the Northeastern United States Data Release
As part of the USGS Sea-Level Rise Hazards and Decision-Support project, this assessment seeks to predict the response to sea-level rise across the coastal landscape under a range of future scenarios by evaluating the likelihood of inundation as well as dynamic coastal change. The research is being conducted in conjunction with resource managers and decision makers from federal and state...

The National Elevation Dataset The National Elevation Dataset
The National Elevation Dataset (NED) is a primary elevation data product that has been produced and distributed by the U.S. Geological Survey (USGS). Since its inception, the USGS has compiled and published topographic information in many forms, and the NED is a significant development in this long line of products that describe the land surface. The NED provides seamless raster...

Coastal National Elevation Database 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...

Evaluating the potential for near-shore bathymetry on the Majuro Atoll, Republic of the Marshall Islands, using Landsat 8 and WorldView-3 imagery Evaluating the potential for near-shore bathymetry on the Majuro Atoll, Republic of the Marshall Islands, using Landsat 8 and WorldView-3 imagery
Satellite-derived near-shore bathymetry (SDB) is becoming an increasingly important method for assessing vulnerability to climate change and natural hazards in low-lying atolls of the northern tropical Pacific Ocean. Satellite imagery has become a cost-effective means for mapping near-shore bathymetry because ships cannot collect soundings safely while operating close to the shore. Also...

Atoll and island coastal communities are highly exposed to sea-level rise, tsunamis, storm surges, rogue waves, king tides, and the occasional combination of multiple factors, such as high regional sea levels, extreme high local tides, and unusually strong wave set-up. The elevation of most of these atolls averages just under 3 meters (m), with many areas roughly at sea level. The lack...

Topobathymetric elevation model development using a new methodology: Coastal National Elevation Database Topobathymetric elevation model development using a new methodology: Coastal National Elevation Database
During the coming decades, coastlines will respond to widely predicted sea-level rise, storm surge, and coastalinundation flooding from disastrous events. Because physical processes in coastal environments are controlled by the geomorphology of over-the-land topography and underwater bathymetry, many applications of geospatial data in coastal environments require detailed knowledge of...

Creating a Coastal National Elevation Database (CoNED) for science and conservation applications Creating a Coastal National Elevation Database (CoNED) for science and conservation applications
The U.S. Geological Survey is creating the Coastal National Elevation Database, an expanding set of topobathymetric elevation models that extend seamlessly across coastal regions of high societal or ecological significance in the United States that are undergoing rapid change or are threatened by inundation hazards. Topobathymetric elevation models are raster datasets useful for...
