Monitoring of Dali Lake based on Sentinel-1 data

The inland lake is an important part of water supplies in arid areas, which is highly sensitive to the changes of hydrological environment and human activities. Lakes located in the arid environment are more sensitive to human activities and climate changes than in other regions. Dali Lake, the important lake in the arid areas of Inner Mongolia, has important index significance. In this paper, an effective method of filtering enhancement with threshold method was developed for rapid extraction and change detection of Dali Lake by using the Sentinel-1 SAR images since 2015. This research provides a reference for further research on lakes in the inland arid area using Sentinel-1 satellite data.
