Use waterway= for simple narrow artificial waterways used to drain nearby land, to remove storm-water or similar. Ditches are usually straight (as opposed to natural streams). Unlike a drain, they are not lined with concrete or other hard materials. They are often found along roads or on the edges of agricultural fields.
They may contain little water or even be dry most of the year – to mark this intermittent=yes may be used.
For artificial drainage waterways lined with concrete or similar, see waterway=drain. For large artificial waterways used for navigation or for transporting useful water, see waterway=canal.
How to map
- Ver também: Waterways
Create a simple linear way, in the direction of flow if this is clear, and add waterway=.
- Consider adding
width=*to indicate the width in metres, for examplewidth=1.5. - If the ditch contains water only part of the time, the tag
intermittent=yesmay be used. - When the ditch passes under a highway or other features in a short tunnel, add
tunnel=culvertandlayer=-1for the underground section.
- Some mappers have used this tag for small, unlined waterways used for irrigation, along with the proposed tag
irrigation=yes. However, this usage contradicts the original definition ofwaterway=as a waterway used to remove excess water. Alternatively, irrigation ditches can be mapped aswaterway=canal+usage=irrigation+width=*
