ABSTRACT
In recent decades, climate change has significantly affected glacier dynamics, resulting in mass loss and an increased risk of glacier-related hazards including supraglacial proglacial lake development, as well catastrophic outburst flooding. Rapidly changing conditions dictate the need for continuous detailed observations analysis climate-glacier dynamics. Thematic quantitative information regarding geometry is fundamental understanding forcing sensitivity glaciers to change, however, accurately mapping debris-cover (DCGs) notoriously difficult based upon use spectral conventional machine-learning techniques. The objective this research improve earlier proposed deep-learning-based approach, GlacierNet, which was developed exploit a convolutional neural-network segmentation model outline regional DCG ablation zones. Specifically, we enhanced GlacierNet2 architecture thatincorporates multiple models, automatic post-processing, basin-level hydrological flow techniques DCGs such that it includes both accumulation Experimental evaluations demonstrate improves estimation zone allows high level intersection over union (IOU: 0.8839) score. provides complete (both zone) outlines at scales, with overall IOU score 0.8619. This crucial first step automating can be used accurate modeling or mass-balance analysis.
