Mapping debris-covered glaciers using multiple data sets in Google Earth Engine by Dr. Zhixing Ruan, Assistant professor at Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences

Abstract: Mountain glaciers have been regarded as an important indicator of climate change, and debris cover, through buffering the impact of temperature changes on glacier ice, can play a key role in regulating glacier ablation. Although numerous techniques for mapping of clean glaciers using remote sensing data have been devised, mapping of partially debris-covered glaciers still remains a bottleneck for the glacier inventory work. In our work, we utilized information from optical remote sensing imagery and digital elevation data based on Google Earth Engine, and introduced active contour algorithm into the automated approach for detecting boundaries of debris-covered glaciers in High Mountain Asia.  The utilization of Google Earth Engine and algorithm, and several case studies will be presented.
