Benchmarks and Datasets

• ISPRS Benchmark on Building elevation elements aims to address this issue by providing a public benchmark dataset and an evaluation framework for performance comparison of building elevation segmentation methods. The dataset will cover 6 different urban areas, 8 building elevation elements categories, and more than 600 million points within 1000 kilometres. A detailed description and benchmark of this dataset will be submitted in the 2023 ISPRS Journal of Photogrammetry and Remote Sensing.
• Indoor dataset. GMMAP: Gnss-denied Environments Multisensorial Mapping and Positioning datasets was collected by a stroller-mounted MLS system featuring one Livox Horizon laser scanner in an underground parking lot with GNSS-denied environment. The point clouds were processed with the LIO-Livox SLAM algorithm provided by Livox, which contains approximately 170 million points covering 8000 m2 area, and RGB data was also collected with a 360-degree camera. The dataset is manually labelled into six categories, including ground, ceiling, column, vehicle, wall, and unclassified.
• The OpenGF dataset aims to address this issue by providing a public benchmark dataset and an evaluation framework for performance comparison of ground filtering methods. The dataset not only covers approximately 47.7 km² with over 542 million points from 4 countries but also contains 9 different terrain scenes. The definitions of the three classes in the dataset are as follows:
• Unclassified (class 0): Low outliers, high outliers.
• Non-Ground (class 1): Buildings, low vegetation, medium vegetation, high vegetation, bridges, cars, and other unclassified objects.
• Ground (class 2): Bare earth, clean water surfaces.
