Climate change is a significant factor that affects both the natural and human components of the coastal landscape. Therefore, assessments and monitoring of vulnerable coastal lands are needed in locations where an ever-increasing population lives in communities at risk from sea-level rise, inundation, and storm surge.
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 and Earth science applications.
The USGS has developed a national inventory of significant topographic changes based on seamless multitemporal elevation data and land cover data. The National Elevation Dataset (NED) and the Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless elevation datasets that can be used to detect and analyze 20th century topographic surface changes in the United States.
