This radar image features Vietnam’s Mekong Delta where the Mekong, the world’s 12th longest river, fans out into tributaries and empties into the South China Sea in Southeast Asia.
Ho Chi Minh (formerly known as Saigon), Vietnam’s largest city and chief port, is visible as white in the upper right corner. The image was obtained by combining three of Envisat’s Advanced Synthetic Aperture Radar (ASAR) acquisitions (on January 9, 007, February 13, 2007 and November 20, 2007) taken over the same area. The colours in the image result from variations in the surface that occurred between those acquisitions. (Source: ESA).
