Kullervo/BRIGHT

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.

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.
