Hi friends, if you map a dyke, ID-editor recently gives a warning that a dyke ought to be a closed (circular) line. On lowland coasts such as in Germany, this demand is a nonsense. Some dyke lines (especially on the North Sea) have a length of several hundreds of kilometers. Nobody can map them in one session. Other coasts, such as on the Baltic Sea, but also in England, have very low sections, that are protected by dykes, and hilly sections that do not require dykes. There the dykes end at slopes of natural hills – which are not mapped, unless they are prominent escarpments.
