A ditch or a trench is a long and narrow way dug in the ground.

Description

The characteristics of a ditch are: it is a man made structure and its primary use is to prevent access to the other side. They may contain little water or even be dry most of the year.

If the main use is to channel water or if it is not totally dry most of the year, consider using waterway=ditch instead of, or in combination with barrier=ditch.

If the ditch you are mapping is natural and holds water (even intermittently), you should use waterway=stream instead.

How to map

Draw a way along the ditch location and add tag barrier=ditch.

Routing

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 and map bridges.

Default access is access=no, that is, it is not possible to cross this feature perpendicularly. Use tag access=* to override it.

It is not possible to route along this feature.

Useful combination

  • width=* to indicate the width of the ditch.
  • waterway=stream or waterway=drain if water may be present at the bottom, you should make this explicit with one of these tags.
  • intermittent=yes for ditches that may be either dry or with present water
  • ditch=ha_ha for the particular type of trench as an ornamental garden feature known as a "ha-ha" (wikipedia:Ha-ha).
