CEMS BurnScars

This dataset provides Harmonized Landsat and Sentinel-2 (HLS) imagery of burn scars and associated masks for the years 2020-2024, primarily over Europe, with some non-European cases (e.g., Mexico, Guatemala). It includes 439 high-quality 512x512 scenes, designed for training geospatial machine learning models for burn scar segmentation. Each TIFF file is a 512x512 pixel scene at 30m spatial resolution. Scenes contain eight bands, and masks have one band. Satellite scenes have bands in Digital Numbers (DN), as per Sentinel-Hub documentation. Each image contains 8 bands (Blue, Green, Red, NIR Narrow, SWIR 1, SWIR 2, QA and dataMask). The class distribution is 90% "NotBurned" and 10% "Burned". All images contain metadata about the event, including the title corresponding to the activation in CEMS, the date range and the area.
