Automating Validation and Update of the NHD

Presenter: Ethan Shavers, USGS National Geospatial Program Center for Excellence in GIS (CEGIS)

Topic: Automating Validation and Update of the NHD

Researchers with the Center of Excellence for Geospatial Information Science (CEGIS) are developing and testing methods for automated validation and update of the NHD using 3DEP data. An overview of this research will be presented, including artificial neural network strategies and geomorphic analysis.
