CorrectExample [#2315]

Minor seasonal water channel. This is frequent feature on flat higland areas, poor on details and covered mostly by monoculture spruce forests. Channel systems are often quite rich and tricky, what is demanding in combination with younger forest with poor visibility. Main problem for mapmaker is to set and hold suitable limit of size and clarity of channels to be mapped, as they vary from sharp and deep young ditches to almost invisible old residues.
