<\/p>\n
\nThe freshwater Lake Constance in Central Europe is pictured in this image from the Sentinel-1A satellite.\n<\/p>\n
\nFormed by the Rhine Glacier during the last Ice Age, it covers an area of about 540 sq km and is an important source of drinking water for southwestern Germany.\n<\/p>\n
\nThe lake has shorelines in three countries: Germany to the north, Switzerland to the south and Austria at its eastern end. Over the water body, however, there are no borders because there is no legally binding agreement on where they lie.\n<\/p>\n
\nIn the lower-right, we can see where the Rhine river flows into the lake from the south, which then flows out of the lake to the west (left). This and other rivers carry sediments from the Alps, extending the coastline and decreasing the lake\u2019s water depth.\n<\/p>\n
\nThe runways of Germany\u2019s Friedrichshafen Airport are visible in the right section of the image. The Aviation & Aerospace Museum is nearby.\n<\/p>\n
\nThis image was acquired on 10 May in \u2018interferometric wide swath mode\u2019 and in dual polarisation.\n<\/p>\n
\nThe radar instrument gathers information in either horizontal or vertical radar pulses, and colours were assigned to the different types. In this image, buildings generally appear pink, while vegetation is green. Areas with lowest reflectivity in all polarisations appear very dark, like the water.\n<\/p>\n
\nSentinel-1A\u2019s radar is still being calibrated following its 3 April 2014 launch, but early images like this give us a glimpse of the kind of operational imagery that this mission will provide for Europe\u2019s Copernicus environmental monitoring programme.\n<\/p>\n
