man_made=embankment is used to map an artificial slope or steep incline built for example to provide a level platform on top for a road or railway line (See ) or to otherwise shape or stabilize the terrain. Such a structure can be built from compacted earth (often stabilized with grass or other plants) or from loose or set stones.
How to map
man_made=embankment should be added to a way drawn with the lower side on right side of the way's direction. It is often rendered with a line featuring dots, triangles or other shapes on the right side to indicate the direction of slope. This is similar to the technique used for barrier=retaining_wall and natural=cliff.
Raised roads, railways, etc.
When mapping a raised highway, railway, waterway or similar with artificial slopes on both sides embankment=yes can be used to document this in a very compact form without additional geometries. Some mappers prefer to map the embankment separately, to do that you map two separate ways on both side of the road or railway line in different directions (according to the rule above) and tag them man_made=embankment.
Natural features with similar scope
- natural=earth_bank - earth bank is an abrupt change in ground level which can be clearly distinguished from its surroundings
- natural=gully - small scale cut in relief created by water erosion
- embankment=* - used to indicate a raised road or other linear feature with embankments on both sides
- cutting=* - the opposite situation with slopes towards the feature in question
- natural=cliff - for vertical or near vertical drops of natural origin
- barrier=retaining_wall - for a artificial vertical or near vertical built wall with a function similar to man_made=embankment
- man_made=dyke - for an embankment (or levee) to redirect or prevent flooding by a river, lake or sea
