Indus River
This Envisat image shows western India and southern Pakistan, with the Indus River snaking through Pakistan’s Sindh province before emptying into the Arabian Sea. The red area in the lower-central portion of the image covers a seasonal salt marsh over Pakistan’s border with western India.
This image is a compilation of three passes by Envisat’s radar on May 15, July 14 and Sep. 12, 2011. Each is assigned a color (red, green and blue) and combined to produce this representation. The colors reveal changes in the surface between Envisat’s passes.
