The Yangtze River is the great water transport artery running across eastern, central and western China, and one of the busiest inland shipping channels in the world. It reaches up to Chongqing and Wuhan and down to Nanjing and Shanghai, linking the factories and ports along its banks into a complete logistics chain that stretches to overseas markets. Every day thousands of cargo ships, container vessels, tankers and working boats move back and forth, carrying coal, ore, steel, grain and containers without pause. The Wuhu section lies in the lower reaches of the Yangtze, with a wide channel and good water depth, making it an important port and shipping hub for the Wanjiang city belt. Vessels are dense here, and anchorages, wharves and branching waterways weave together. Seen from space, these ships look like little moving dots of light on the river. They reflect how active shipping is, and they offer an intuitive basis for water traffic management, vessel flow statistics, sand mining supervision and channel safety monitoring.

The images below are 0.7m resolution satellite images of ships in the Wuhu section of the Yangtze River, taken by the GF7 satellite in April 2026. Hull outlines, wake trails and berth distribution are clearly recognisable, so the images can be used to look at vessel type composition, queuing and berthing conditions - excellent material for studying the operating state of inland river shipping.
