"Hetu Zhijian" is a hydrological data visualization management platform based on digital twin technology, which aims to provide efficient and intelligent hydrological monitoring and management solutions. By collecting and synchronizing hydrological data in real time, the platform can visually display the changing trend of the water environment, help users to analyze the hydrological situation in depth, predict potential risks, and respond quickly. The platform uses advanced data visualization tools to present hydrological information with three-dimensional models and multi-dimensional charts, providing more intuitive and easy-to-use intelligent support for decision makers and managers. At the same time, "Hetu Zhijian" also has data prediction and intelligent early warning functions to help users achieve accurate hydrological management and environmental protection.
