So a retaining wall (or reinforced "retaining slope"?) is when an
I render the things that OSM shows as cliffs, because sometimes surprises
lurk between the contour lines. Otherwise, when I care, on my own maps I
render elevation contours (and hence have no use for the cliff height in
the data base). In a spot like

I would hope that a scheme can be had that is one sided - and the same
for cliff, embankment, cutting etc.
As such it should be one sided. After all another side could have a
different slope/area. A single sided scheme could be used for 2 sided or
multi sided structures by many separate one si
It makes sense that a road embankment have only one slope.
Perhaps for a levee[1] we need a specific tagging system because a levee
has always two slopes.
I'm native of the Po Valley where levees are along every river (Volker can
confirm it ;) ).
A levee for flood prevention could be simple[2] bu
'Embankment' is frequently used for a built-up structure on a steep
hillside that keeps a road, railroad, or similar feature from sliding into
a gorge or river. See

To my understanding of the English term, an "embankment" is the equivalent
of dyke or levee and is a long, narrow man-made elevation. Therefore they
always have two slopes of opposite direction
Not all embankment have 2 slopes .. nor does a 'slope' describe all of
the properties of an embankment. The same problem exists for a 'cliff'
and a 'cutting' ... and stairs that cover a large area. So use what has
been done for them as a guide.
What are the key properties of these features ...
If you want to micromap slopes you should create a new key "slope" or
something similar. An embankment has two slopes. It is equivalent to dyke
or levee. The one-side embankments that are defined in the OSM wiki, are in
reality slopes and should be retagged accordingly.
Independently of the name u
Currently we are mapping only one side of the embankment (I think it's the
upper side, but am not sure if the wiki says this explicitly), with the
direction. What we would IMHO need is a way to map the lower side as well
and to combine both. A closed polygon will not work I believe.
The obvious so
