IMPROVED ON SNOW COVER EXTRACTION IN MOUNTAINOUS AREAS BASED ON MULTI-FACTOR NDSI DYNAMIC THRESHOLD

The microwaves used in current products to measure snow depth don't pick up on the small changes in snow depth on the Qinghai-Tibet Plateau. To deal with these issues, our study suggests a new way of doing things. This uses AutoML, data from AMSR-2 and other geographical information. Our results show that the method we used is good for checking how snow cover changes in mountain areas.
