LiDAR data processing involves a sequence of computational techniques used to convert raw laser return measurements into meaningful geospatial information. The process begins with data acquisition, where airborne, terrestrial, or spaceborne LiDAR systems emit laser pulses and record their return time, intensity, and multiple echoes. Raw point cloud data is then georeferenced using GPS and inertial measurement unit data to ensure accurate spatial positioning. Noise filtering is a crucial early step, as it removes outliers caused by atmospheric interference,
