Lake Constance as shown here was captured by the Sentinel-1A satellite. Formed in the last Ice Age, the lake covers an area of about 540 sq km. Providing drinking water for southwestern Germany.
Lake Constance has shorelines in three countries: Germany to the north, Switzerland to the south and Austria to the east. In 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’s water depth.
We can see the runways of Germany’s Friedrichshafen Airport and the nearby Aviation & Aerospace Museum in the right section of the image
