A U.S. Army Corps of Engineers geophysicist operates equipment used to detect and classify metal objects in the subsurface as potentially a target of interest, such as a munition. The U.S. Army Engineering and Support Center, Huntsville's Environmental Munitions Center of Expertise hosted a technical training seminar for U.S. Army Corps of Engineers geophysicists focused on familiarization of simultaneous location and mapping, or SLAM, technology that will increase mapping production rates in thick vegetation where previously only tape measures or line-of-site robotic total station (RTS) technologies were available.
