<div bgcolor="#FFFFFF" text="#000000"> Hi,<br>
<br>
I'm looking for how to map what is called in French a <a
moz-do-not-send="true"
href="http://www.cnrtl.fr/definition/talus"
target="_blank">talus</a> (Google's translation).<br>
I would call this a 1.8m simple step running for some
reason for several 100s meters across meadows.<br>
Steep slope. There are "top of slope" and "bottom of
slope" lines. Rest is perfectly flat either side.<br>
It might be the remnants of a old canal's bank whose other
side would have been eroded by the often overflowing
nearby river.<br>
A "talus" made of plain ground is often frequent at one
side of a path or track.<br>
According to the wiki, it's not a "scree" nor a "shingle".
It's much less matter specific.<br>
So what?<br>
I'll use "scree" unless/until I hear of better for a
French talus.<br>
<br>
Cheers <br>

<div dir="ltr">I'm not entirely sure this is what you have in
mind, but in the cases where it is associated with roads, I've
seen historic=hollow_way (when the slope is caused by the fact
that there's an old road), and "embankment" or "cutting" when
the slope is deliberatly constructed. In other cases, I've seen
what I think you describe mapped as natural=cliff, which is
obviously wrong, but does get the message accross. For example
where sand or rock was quarried this is common to see on the
map. I'm hoping someone has seen better ideas.</div>

Thanks for all your fast answers from which I had to choose the
first one to reply to.<br>
A photo was asked. I might go back there to make one, but you
wouldn't see more that the surface of a meadow looking like this on
a long distance, at varying steepness and width.<br>

SPW(allonie) PICC numerical imagery</a> (JOSM) overlay allowing me
to map it. As you zoom out, you will see that the aerial photo is
darker along that line.<br>
The Cartoweb background (Fond de Plan) draws it as the typical
"behind which to hide" line of old military maps.<br>
Well, in OSM parlance, it's not a cree because there is no cliff
(1), not a shingle because there is no sea and not an embankment
because there is no road to be an attribute of.<br>
Well, as I said it, what I'm facing seems to be, as I found more
specifically, the remnants of <a
href="https://fr.wikipedia.org/wiki/Projet_de_canal_Meuse_et_Moselle#N.C2.B012_Devant_Rosi.C3.A8res">this
old canal @ N°12</a>. The river often overflows as high as above
the road. When the water goes back, it washes the left bank of the
canal towards the river but the right bank is mostly just overflown.<br>
<br>
So, there's nothing in OSM for that precisely.<br>
Would man_made=dyke be the most resembling and acceptable with an
explanation note?<br>
<br>
Thanks and TIA,<br>
Cheers

(1) there's a very beautiful one, but at the other side of the
river, called "La Roche aux Faucons" (Falcons' Cliff).<br>
