  • Detecting sound in the Arctic

    The U.S. Army Engineer Research and Development Center’s Cold Regions Research and Engineering Laboratory’s (CRREL) signature physics branch is obsessed with sound -- or more specifically, the way it travels through the atmosphere and interacts with terrain – and methods for extracting information from sound signals.
  • USACE Drones provide an eye in the sky for engineers

    In March of 2020, Geographic Information System Specialist Rachel Byrd and Project Engineer Ryan Fagan with the U.S. Army Corps of Engineers Louisville District’s Engineering Division piloted the inaugural Small Unmanned Aircraft System flight for the district in an open field at the Parklands of Floyds Fork in Louisville, Ky.
  • CRREL tests new ways to measure smoke density

    CRREL partners with the U.S. Coast Guard's Research and Development Center and the Environmental Protection Agency to test an aerial drone to determine how effective the device is for measuring air quality and environmental impact of burning oil on water. The aerial drone is a new means of capturing these measurements, and CRREL is one of the few federal agencies with the knowledge, permissions, licenses, and facilities to accommodate in situ burns.
  • First Generation Automated Assessment of Airfield Damage from LiDAR Point Clouds

    Abstract: This research developed an automated software technique for identifying type, size, and location of man-made airfield damage including craters, spalls, and camouflets from a digitized three-dimensional point cloud of the airfield surface. Point clouds were initially generated from Light Detection and Ranging (LiDAR) sensors mounted on elevated lifts to simulate aerial data collection and, later, an actual unmanned aerial system. LiDAR data provided a high-resolution, globally positioned, and dimensionally scaled point cloud exported in a LAS file format that was automatically retrieved and processed using volumetric detection algorithms developed in the MATLAB software environment. Developed MATLAB algorithms used a three-stage filling technique to identify the boundaries of craters first, then spalls, then camouflets, and scaled their sizes based on the greatest pointwise extents. All pavement damages and their locations were saved as shapefiles and uploaded into the GeoExPT processing environment for visualization and quality control. This technique requires no user input between data collection and GeoExPT visualization, allowing for a completely automated software analysis with all filters and data processing hidden from the user.

  • Corps of Engineers leveraging drone technology to capture imagery after flooding in Midwest

    In mid-to-late March, flood water covered much of eastern Nebraska, western Iowa, and northern Missouri. Due to the extreme amount of water in the area, members of the U.S. Army Corps of Engineers, Omaha District had trouble getting to the more than 500 miles of compromised levees to surveille for damage so they turned to a new option to the Omaha District....drones. Drones, or unmanned aerial systems, offer the District the opportunity to fly over affected levees and other flooded areas without putting District employees in danger.
  • NR 18-030: Public reminded of drone policies at Corps, TVA projects

    NASHVILLE, Tenn. (Nov. 6, 2018) — The public is reminded of the policies of the U.S. Army Corps of Engineers Nashville District and Tennessee Valley Authority that govern the operation and use of recreational unmanned aerial systems (UAS or drones) . The Corps of Engineers operates and maintains navigation locks at TVA dams where the TVA drone policy applies.
  • Corps unveils policy for operation of unmanned aerial systems at Nashville District projects

    Nashville, Tenn. (Aug. 5, 2016) – The U.S. Army Corps of Engineers Nashville District has a new policy that governs the operation and use of recreational unmanned aerial systems (UAS) at all Nashville District lakes within the Cumberland River Basin.
