Shang-hai, http://www.guardian.co.uk/environment/gallery/2012/feb/08/satellite-eye-in-pictures#/?picture=385606531&index=17 "Shanghai sits at the mouth of the Yangtze River where it empties into the East China Sea. To the north of the river is Chongming island, with the smaller Changxing island midstream. The islands are important areas for agriculture, evidenced in this image by the patchwork of croplands. The dark area hugging Changxing island is the Qingcaosha reservoir."
