It accurately divides the national water system map into provincial, municipal and district-level administrative divisions across China. The dataset includes the national water system map of China, water system distribution within administrative divisions, supports layered display of river networks, and labels the names of primary, secondary and tertiary major rivers. The data is intuitive, reliable in quality, and conforms to the project usage standards.
