Shea Hammond, a member of the U.S. Army Engineer Research and Development Center (ERDC) Environmental Laboratory’s (EL) Unmanned Aerial Systems (UAS) team, monitors a Light Detection and Ranging (LiDAR) data-collecting aircraft as it begins its survey of a section of the Bayou Pierre watershed near Vicksburg, Mississippi. Researchers from the ERDC’s Coastal and Hydraulics Laboratory recently collaborated with the EL UAS team for a project to develop a rapid watershed assessment approach using the remote sensing technology.
