As is clear from the Taginfo statistics shown to the right, it is much more common to use embankment=yes than man_made=embankment. This page has been created to document the tag, but also to draw attention to the alternative and more popular method of tagging such a feature. Note also that man made=embankment is gaining popularity - in 2014 embankment=yes was used 8 times more, in 2015 it dropped to 5 times more.s

When mapping a highway, railway or waterway on top of an embankment tagging the way with embankment=yes is an obvious choice. If you want to tag the embankment as an own feature however, you may use man_made=embankment on a separate way on each side of the other way.


In transportation an embankment is a raised bank to carry a road, railway, or canal across a low-lying or wet area. If this low-lying area is permanently or tidally flooded, then the raised bank is called a causeway.

It can also be an artificial bank raised above the immediately-surrounding land to redirect or prevent flooding by a river, lake or sea. See also: Proposed_features/Dyke (sic).

See wikipedia:Embankment


Add man_made=embankment to a way with the left-hand side of the way being the high side and the right-hand side being the low side (this rule same as cliff and retaining_wall).

When micro-mapping, and if appropriate, you can also draw two parallel ways in opposite directions and add man_made=embankment to both.

  • To represent a raised finger of land (as in the illustration): draw two ways bordering the raised land, each tagged man_made=embankment and going in opposite directions.
  • To present a banked enclosure (such as an iron-age hill fort): draw two ways with the outer way travelling anticlockwise and the inner way clockwise. Additional ways can be used to present ditches, scarps, aprons and terraces in large sites. Note that if a closed way is drawn without two breaks (creating two separate but connected ways) then it will be interpreted as an area and not displayed in the Standard layer.
