GlacierDeep

GlacierDeep is a research initiative and software framework that applies deep learning to glaciology. It aims to improve automated glacier mapping, thickness estimation, and velocity field derivation from multi-source remote sensing data.

Origin and development: The project began in 2019 as a collaboration among universities and data-science laboratories focused on making glacier data more accessible and reproducible. The first public release followed in 2020, with ongoing updates that incorporate new imagery sources and modeling approaches.

Architecture and data: GlacierDeep provides data ingestion pipelines for Sentinel-1 and Sentinel-2, Landsat, ICESat-2, and digital elevation models, along with preprocessing, quality control, and storage. It supports both supervised segmentation of glacier outlines and estimation of surface velocity through feature-based or deep-learning methods.

Outputs and accessibility: The framework includes pretrained models for outline delineation, velocity mapping, and thickness proxies, plus tools to train custom models. Outputs are provided in GIS-friendly formats and can be integrated with existing glacier inventories.

Impact and community: Adoption by regional observatories and academic groups has improved automation of glacier monitoring in data-poor regions. The project emphasizes open data, reproducible workflows, and interoperability with other glaciology and remote-sensing tools.

Limitations and outlook: Performance depends on data availability and quality. Cloud cover, snow or ice misclassification, and regional variability can affect results. Ongoing work focuses on uncertainty estimation, domain adaptation, and expanding sources such as commercial imagery and SAR-based products.
