The Chinese city of Shanghai sits at the mouth of the Yangtze River where it empties into the East China Sea. To the north is Chongming Island and the smaller Changxing Island just below. These are important areas for agriculture – evident in this image by the patchwork of croplands. The dark area hugging Changxing Island is the Qingcaosha Reservoir. This SPOT-5 image was acquired on 25 June 2009, with a resolution of 10 m.
