Construction and Application of the Yunnan-Guizhou Plateau Transparent Lakes Data Sharing Platform

Lakes are an important part of the freshwater ecosystem. There are eleven major natural lakes in the Yunnan-Guizhou Plateau, accounting for 5.05% of China's freshwater resources. To achieve 3D dynamic monitoring of lakes on the Yunnan-Guizhou Plateau, visualize information on underwater topography, water surplus and deficit and water quality changes, and provide basic scientific data for water resource protection, we built the Yunnan-Guizhou Plateau Transparent Lakes Data Sharing Platform. Using IoT, middleware, big data, cloud computing, AI and other technologies, the platform collects UAV-SFM and shipboard bathymetry data, integrates multi-source spaceborne DEM and lake level series, the platform integrates the data fusion tools and algorithmic models, to achieve underwater terrain modelling and estimation of 11 major lakes in the Yunnan-Guizhou Plateau, and provides 3D services for the lakes. In addition, by connecting lake monitoring sites in real time, the platform continuously collects and stores lake water quality data, and builds lake ecological monitoring models to assess water quality and predict water pollution.
