Datasets description

&Emsp Deep learning-based methods have attracted great attention in glacier extraction due to their advantages over traditional techniques. In this study, we verified the feasibility and effectiveness of LandsNet architecture in glacier extraction, and we applied the improved LandsNet (M-LandsNet) to extract the glacier contours in the headwaters of the Three Rivers. Two scenarios were compared using the band ratio method, U-Net, U-Net++, GlacierNet, SaU-Net, U-Net+cSE and LandsNet. The analysis of the two scenarios shows that M-LandsNet has the best performance and generalization ability among the 1986 methods.

Data source description

&Emsp; Obtaining a reliable glacier inventory is the first step in training a deep learning network. In this study, SCGI is used as a real glacier profile and is considered as ground truth.

Data processing method

&Emsp;We further extracted the glacier outlines in the Three Rivers headwaters region in a total of 40 periods using M-LandsNet and manual adjustment.

Data quality description

&Emsp;Good quality of data
