Fine-tuning DOFA
Figure: Schematic illustration of fine-tuning DOFA geo-foundational model for glacial lake mapping using Glacial Lake-Bench.
GLB coverage
Figure: Compilation of Glacial Lake-Bench across RGI regions. GLB consists of Sentinel-1 (VV, VH), Sentinel-2 (Blue, Green, Red, NIR, SWIR-11, SWIR-12, NDWI), and topographic layers (slope, elevation). The map shows the ratio between total lake area reported by Zhang et al. (2024) and lake area covered by GLB.
Split map
Figure: Spatial distribution of training, testing, and validation sites globally.
Challenging cases
Figure: Example DOFA results on the Glacial Lake-Challenge set: clouds, frozen lakes, shadows, and very small lakes (panel e).
