Researchers have introduced new Land Use Land Cover (LULC) classification schemes and a benchmark dataset for multispectral LiDAR data. They evaluated seven deep learning models, finding that Point Transformer V3 performed best, achieving an mIoU of 79.4% for 8 classes and 58.9% for 20 classes. The study demonstrated that multispectral information significantly enhances classification accuracy compared to geometry-only inputs, highlighting its value for detailed material discrimination. AI
