The Dianchi Watershed in Yunnan Province, China extends across an area of about 2707 km2, among which Lake Dian has a surface area of nearly 298 km2. With a population of more than 4 million in 2018, this area has experienced significant urban and agricultural development since the late 1980s, which has brought on various environmental problems such as water pollution. In this study, we developed a remote sensing approach to map land cover types for the Dianchi watershed using satellite imagery and machine-learning methods. To support the remote sensing work, we conducted two field trips to the study site in Summer 2017 and Winter 2018. Some preliminary results are reported here.
