BRIGHT: A globally distributed multimodal building damage assessment dataset with very-high-resolution for all-weather disaster response

Overview BRIGHT is the first open-access, globally distributed, event-diverse multimodal dataset specifically curated to support AI-based disaster response. It covers five types of natural disasters and two types of man-made disasters across 12 regions worldwide, with a particular focus on developing countries. About 4,500 paired optical and SAR images containing over 350,000 building instances in BRIGHT, with a spatial resolution between 0.3 and 1 meters, provides detailed representations of individual buildings, making it ideal for precise damage assessment.   IEEE GRSS Data Fusion Contest 2025 BRIGHT also serves as the official dataset of IEEE GRSS DFC 2025 Track II. Please download dfc25_track2_trainval.zip and unzip it. It contains training images & labels and validation images.  Benchmark code related to the DFC 2025 can be found at this Github repo.  The official leaderboard is located on the Codalab-DFC2025-Track II page.    Paper & Reference Details of BRIGHT can be refer to our paper.  If BRIGHT is useful to research, please kindly consider cite our paper  @article{chen2025bright, title={BRIGHT: A globally distributed multimodal building damage assessment dataset with very-high-resolution for all-weather disaster response}, author={Hongruixuan Chen and Jian Song and Olivier Dietrich and Clifford Broni-Bediako and Weihao Xuan and Junjue Wang and Xinlei Shao and Yimin Wei and Junshi Xia and Cuiling Lan and Konrad Schindler and Naoto Yokoya}, journal={arXiv preprint arXiv:2501.06019}, year={2025}, url={arxiv.org, } License Label data of BRIGHT are provided under the same license as the optical images, which varies with different events.
