چکیده
Glaciers in High Mountain Asia (HMA) have a significant impact on human activity. Thus, detailed and up-to-date inventory of glaciers is crucial, along with monitoring them regularly. The identification debris-covered fundamental yet challenging component research into glacier change water resources, but it limited by spectral similarities surrounding bedrock, snow-affected areas, mountain-shadowed issues related to manual discrimination. Therefore, use fewer human, material, financial necessary develop better methods determine the boundaries glaciers. This study focused mapping using combination technologies such as random forest (RF) convolutional neural network (CNN) models. models were tested Landsat 8 Operational Land Imager (OLI)/Thermal Infrared Sensor (TIRS) data Advanced Spaceborne Thermal Emission Reflection Radiometer Global Digital Elevation Model (ASTER GDEM), selecting Eastern Pamir Nyainqentanglha typical areas Tibetan Plateau construct classification system. performances different classifiers compared, classifier construction strategies optimized, multiple single-classifier outputs obtained slight differences. Using relationship between surface area covered debris machine learning model parameters, was found that coverage directly determined performance mitigated affecting detection active inactive Various integrated ascertain best for
