\nThis Sentinel-2A false colour image shows agricultural structures in the Abruzzo region of central Italy.\n<\/p>\n
\nThe varying shades of red and other colours across the entire image indicate how sensitive the satellite\u2019s multispectral camera is to differences in vegetation cover and chlorophyll content. This is used to provide key information on plant health.\n<\/p>\n
\nFor this image, the brighter reds indicate more photosynthetically active vegetation, as seen in many of the fields and along the Roveto Valley Abruzzi mountain range in the lower left.\n<\/p>\n
\nIn the very centre of the image a cloud and its shadow are clearly visible over the plain.\n<\/p>\n
\nOn the central left side we can make out an industrial area, whereas the town of Avezzano is just further north.\n<\/p>\n
\nThe entire area in the centre is where the Fucino Lake used to be. The Romans founded settlements on its banks as the lake provided fertile soil and a large quantity of fish. However, the lake was believed to harbour malaria, and, not having a natural outflow, it repeatedly flooded the surrounding arable land.\n<\/p>\n
\nIn 1862 Prince Alessandro Torlonia commissioned a Swiss engineer to drain what was once Italy\u2019s third largest lake. A 6.3 km-long and 21 m-wide canal was dredged. By 1875 the lake was completely drained, and the resulting plain is one of Italy\u2019s most fertile regions today. \n<\/p>\n
\nA canal is clearly visible running horizontally across the centre of the image.\n<\/p>\n
\nIn the lower-right section of the plain is a cluster of dots surrounded by fields: the Fucino Space Centre, one of the largest civil space centres in the world, a node for missions operations. \n<\/p>\n
\nThe dots are the 100 antennas sited on an extension of 370 000 sq m. Fucino also hosts one of the control centres that will manage the 30 satellites and the operational activities of Galileo, the European satellite navigation system.\n<\/p>\n
