This study presents a novel filtering methodology for Mobile LaserScanning (MLS) data using robust iterative reweighting. Initially, 3Dpoint clouds are projected onto a 2D grid to create surfaces fromthe lowest points. Weights are assigned based on the Height AboveGround (HAG) of these points. Ground points are distinguished byapplying a surface function to the dataset via iterative reweighting.Among the tested four robust weight functions, the Denmark andBeaton-Tukey functions outperformed others, achieving total errorvalues of 2.30 and 2.32 across three test areas, respectively. Thismethod efficiently filters MLS data, irrespective of ground pointproportions.
