This orthorectified image shows the Limfjord, a shallow sound in Denmark that separates the island of Vendsyssel-Thy from the rest of the Jutland Peninsula. It extends from Thyborøn Channel on the North Sea to Hals on the Kattegat.
The sound is approximately 180 kilometres long and of an irregular shape with several bays, narrowings, and islands, most notably Mors (left). It is deepest at Hvalpsund (24 metres). Its main port is Aalborg, visible as a bright white area at the right edge of the image.
