(a) Location of the 15 national priority lakes in Indonesia for management and spatial planning. At these locations, a test case study of AWEI threshold improvement was conducted, which represented the characteristics of other lakes. (b) Toba Lake, located in North Sumatra Province, Indonesia, was used as a test case study area to develop an AWEI threshold improvement model to detect lake surface water on remotely sensed optical data.
