This satellite image of Lake Constance was acquired on May 10, 2014 in ‘interferometric wide swath mode’ and in dual polarization. The radar instrument gathers information in either horizontal or vertical radar pulses, and colors 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. Source: ESA.

Where is the Only Area in Europe Where no Borders Exist?

Lake Constance’s shoreline touches three different countries: Germany to the north, Switzerland to the south and Austria at its eastern end. The water body itself contains no borders since there is no legally binding agreement between the three countries.
