![Cryo-Bench Overview](assets/cryo-bench_data.png) **Cryo-Bench** is a community benchmark that evaluates geospatial foundation models (GFMs) on five cryosphere remote sensing tasks spanning glacial lakes, supraglacial debris, sea ice, and calving fronts. It is built on top of the [PANGAEA](https://arxiv.org/abs/2412.04204) evaluation protocol using multi-sensor satellite imagery from Sentinel-1/2, Landsat-8, WorldView-2, and historical SAR missions. --- ## ๐Ÿงฐ Code The full benchmarking code is available in the [`Cryo-Bench/`](https://github.com/Sk-2103/Cryo-Bench/tree/main/pangaea-bench) directory, which contains dataset configs, encoder definitions, and decoder heads built on top of [PANGAEA](https://arxiv.org/abs/2412.04204). ## ๐Ÿ“‹ Tasks & Datasets Cryo-Bench includes five benchmark tasks covering key components of the cryosphere: | Dataset | Component | Location | Sensors | Classes | Ancillary Data | Paper | Download | |---------|-----------|----------|---------|---------|----------------|-------|----------| | **GSDD** | Supraglacial Debris | Global | Sentinel-2 | Binary | Slope, Elevation, Velocity | [Article](https://www.sciencedirect.com/science/article/pii/S2666017225001257) | [Zenodo](https://zenodo.org/records/17161810) | | **GLID** | Glacial Lakes | Himalayas | WorldView-2, Sentinel-2, Landsat-8, Gaofen-2 | Binary | โ€” | [Article](https://www.sciencedirect.com/science/article/pii/S002216942500410X) | [Zenodo](https://zenodo.org/records/14838695) | | **GLD** | Glacial Lakes | Himalayas | Sentinel-2 | Binary | SAR Coherence, Slope, Elevation | [Article](https://www.sciencedirect.com/science/article/pii/S1569843222002734) | [Zenodo](https://zenodo.org/records/16986936) | | **SICD** | Sea Ice | Canadian & Greenlandic Arctic | Sentinel-1 | Multiclass | Incidence Angle | [Article](https://egusphere.copernicus.org/preprints/2023/egusphere-2023-2648/) | [HuggingFace](https://huggingface.co/datasets/torchgeo/ai4artic-sea-ice-challenge) | | **CaFFe** | Calving Fronts | Greenland, Alaska, Antarctic Peninsula | ERS-1/2, Envisat, RADARSAT-1, ALOS PALSAR, TSX, TDX, Sentinel-1 | Multiclass | โ€” | [Article](https://essd.copernicus.org/articles/14/4287/2022/) | [PANGAEA](https://doi.pangaea.de/10.1594/PANGAEA.940950) | --- ## ๐Ÿ“ฅ Sample Usage (Download Data) The dataset contains the exact training, validation, and test splits used in **Cryo-Bench**, covering the **SICD, GLID, GLD, GSDD, and CaFFe** datasets. - Install the dependency: ```bash pip install huggingface_hub ``` - Download all datasets at once using the script provided in the GitHub repository: ```bash python download_data.py ``` - Download specific datasets only: ```bash python download_data.py --datasets GLID GLD SICD ``` ## ๐Ÿ† Benchmark Results Table below reports mIoU (โ†‘) for all models evaluated with **frozen encoders** and **100% training data** using the UPerNet decoder. Rank (โ†“) is averaged across all five tasks. Baseline models (U-Net, ViT) are trained from scratch. > **Bold** = best performance ยท *Italic* = second best | Model | GLID | GLD | SICD | CaFFe | GSDD | Avg. mIoU โ†‘ | Avg.
