Development of a national seamless database of topography and hydrologic derivatives Development of a national seamless database of topography and hydrologic derivatives

The recent completion of the National Elevation Dataset (NED) and the National Hydrography Dataset (NHD) has provided an avenue for nationwide development of topographically derived hydrologic data layers at a scale of 1:24,000. This multilayer dataset of hydrologic derivatives, entitled the Elevation Derivatives for National Applications (EDNA), is being developed by a consortium of...

Field observations of swash zone flow patterns and 3D morphodynamics Field observations of swash zone flow patterns and 3D morphodynamics

Rapid video measurements of foreshore morphology and velocity were collected at Duck, NC in 1997 to investigate sediment transport processes in the swash zone. Estimates of foreshore evolution over a roughly 30 m cross-shore by 80 m alongshore study area were determined using a stereogrammetric technique. During the passage of a small storm (offshore wave heights increased from 1.4 to 2...

Quantifying hurricane-induced coastal changes using topographic lidar Quantifying hurricane-induced coastal changes using topographic lidar

USGS and NASA are investigating the impacts of hurricanes on the United States East and Gulf of Mexico coasts with the ultimate objective of improving predictive capabilities. The cornerstone of our effort is to use topographic lidar to acquire pre- and post-storm topography to quantify changes to beaches and dunes. With its rapidity of acquisition and very high density, lidar is...

Planetary Interactive GIS-on-the-Web Analyzable Database (PIGWAD) Planetary Interactive GIS-on-the-Web Analyzable Database (PIGWAD)

The United States Geological Survey (USGS) in Flagstaff, Arizona is producing a Web-based, user-friendly interface that integrates powerful Geographic Information Systems (GIS) statistical and spatial relational tools for analyses of planetary datasets. The interface, known as “Planetary Interactive GIS-on-the-Web Analyzable Database” (PIGWAD), provides database support for the research...
