ASTER VNIR Level 1B

The world's largest mangrove forest with the total area of around 5,800 sq.km lies cross-border in southwest Bangladesh and southeast India in the wetland on the delta at the confluence of the Ganges, Brahmaputra and other rivers flowing from headstream of Himalaya into the Bay of Bengal. About 60 percent of the area of the Sundarbans is in Bangladesh, and another 40 percent is in India. The image captures the view of the Bangladesh River.

The whole Sundarbans area is intersected by a complex network of numerous tidal waterways of various sizes, and is mostly uninhabitable. Mangrove forest protects the area from the threat of cyclone, and it is home to a variety of precious and endangered species of wildlife. It has been the largest habitat in the Indian subcontinent for the Bengal tiger, which is on the verge of extinction. The Bangladesh side of the Sundarbans has been declared a natural heritage of World Heritage site in 1997, and the India side, in 1987.
