  • 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.
  • ERDC researchers developing low-cost, rapid watershed assessment

    Researchers from the U.S. Army Engineer Research and Development Center (ERDC) have partnered with the U.S. Army Corps of Engineers (USACE) Vicksburg District to develop and test a low-cost, rapid watershed assessment using remote sensing technology to evaluate problems associated with watershed instability including erosion, sedimentation, flooding and environmental degradation.
  • 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.
