Description

The LiDAR point cloud was classified across the dataset with a classification macro designed to achieve a high-quality ground surface classification. Classification was applied to LiDAR points stored in a tiled dataset. Data from neighbouring tiles was included in the classification process to ensure consistent results at tile boundaries. Manual classification improvements were applied to the point classes identified in the table below within the scope of the project boundary.
