Satellite imagery gives a glimpse of the site where China has commenced construction on what will become the world's largest dam and China's most ambitious infrastructure project since the Three Gorges Dam.

The project on a river that runs through Tibet and India downstream could dwarf the Three Gorges Dam when completed.
