UAV-Based Remote Sensing for Detection and Visualization of Partially-Exposed Underground Structures in Complex Archaeological Sites

Abstract: The utilization of remote sensing technologies for archaeology was motivated by their ability to map large areas within a short time at a reasonable cost. With recent advances in platform and sensing technologies, uncrewed aerial vehicles (UAV) equipped with imaging and Light Detection and Ranging (LiDAR) systems have emerged as a promising tool due to their low cost, ease of deployment/operation, and ability to provide high-resolution geospatial data. In some cases, archaeological sites might be covered with … Show more

“…Unmanned aerial vehicles (UAVs), renowned for their agility, versatility, speed, and cost-effectiveness, serve as invaluable platforms for aerial photography, enabling the swift capture of high-resolution images with vast potential for generating geographic mapping data [ 1 , 2 ]. Over recent decades, UAV photogrammetry has found applications across various disciplines within the geosciences, including sedimentology [ 3 , 4 ], earthquake geology [ 5 , 6 ], structural geology [ 7 ], geomorphology [ 8 ], engineering geology [ 9 , 10 ], archaeology [ 11 , 12 ], forestry [ 13 , 14 ], and landscape evolution and natural hazards [ 15 , 16 ]. Innovative techniques such as RTK or PPK aero photogrammetric surveying have yielded numerous accurate 3D models [ 7 , 17 ].…”

“…Tree trunks are modeled as cylindrical features to provide horizontal control and ground patches are used as plane features to provide vertical control. To extract these features, initially, the modified Cloth Simulation Filter (mCSF) (Shin et al, 2023) is employed to derive a Digital Terrain Model (DTM) for each IS. Considering a 0.2m for bare-earth threshold, the points are then divided into above-ground and bare-earth points, which are utilized for tree trunk and ground patch extraction, respectively.…”

“…Using real-time kinematic (RTK) GPS positioning facilitates the replication of precise survey paths [24]. It is incorporated with signal processing techniques like cross-correlation-based background subtraction and interference suppression, ensuring the accurate identification of subsurface targets [25,26]. Drone-borne GPR enables the mapping of geotechnical properties such as the soil moisture [27] and field-scale soil electrical conductivity [28].…”
