This multi-temporal image, acquired over the city of Valencia (one of the largest cities in Spain), shows the urban development over a period of seven years along the Tura River. The image is a result of a merge of three separate acquisitions performed by the Envisat satellite (07 Aug 2010 in red, 18 Oct 2003 in green) and by ERS-2 (04 Nov 2011 in blue).
