Researchers have introduced PCFootprint, a new large-scale dataset designed for extracting vectorized building footprints from aerial LiDAR point clouds. This dataset, comprising over 33,000 tiles covering diverse landscapes, aims to overcome limitations of image-based methods, such as occlusions and lack of explicit elevation data. PCFootprint includes a cross-domain test set to evaluate generalization capabilities and establishes benchmarks for existing methods, revealing challenges like high intra-class variance and data imbalance.
