WebApr 9, 2024 · Separating point clouds into ground and non-ground measurements is an essential step to generate digital terrain models (DTMs) from LiDAR (light detection and ranging) data. Many filtering algorithms have been developed. WebIt is straightforward to make use of the height above ground level and return intensity values to classify LiDAR point cloud data. While the return intensity values are not typically normalized between ight lines, the relative intensity of points may be useful in distinguishing di erent materials.
