Analysis Using High-Precision Airborne LiDAR Data to Survey Potential Collapse Geological Hazards

<div>Comparison of the traditional filtering method and the geological filtering method for displaying microgeomorphology: (a, b) the results gained with the traditional filtering algorithm and (a′, b′) the results of using the optimization filtering algorithm, which produces smaller landforms (steep hills, clastic rocks).</div>
