| +/- barrier=ditch
A ditch, trench or ravine
A ditch, trench or ravine, usually with a stream at the bottom, that is not easily crossed, especially if not on foot.
There is often a waterway=ditch running along the bottom of the trench - that is, tagged on the same way. Consider using waterway=ditch instead of, or in combination with, barrier=ditch, whenever the ditch is not totally dry most of the year.
Given the current use figures (there are hundredfold more uses of waterway=ditch than there are uses of barrier=ditch), a waterway=ditch can be taken to imply that it is also a barrier=ditch, but not vice versa.
How to map
Remember that any barrier tag may interpreted as impassible for pedestrians. Leave a gap in the barrier where you can pass the ditch on foot (or map a bridge).
Tags to use in combination
- width=* - The width of the ditch in metres (unless other unit is specified).
- waterway=stream or waterway=drain - Although a ditch might "usually" have a stream at the bottom, you should make this explicit with one of these tags.
- ditch=ha_ha - Only for the particular type of trench as an ornamental garden feature known as a "ha-ha" (wikipedia:Ha-ha).
