<p>How do we know that 61 precious uses of the word berm all meant
the same? without verifying each one .</p>
<p>The english wikipedia <a class="moz-txt-link-freetext" href="https://en.wikipedia.org/wiki/Berm">https://en.wikipedia.org/wiki/Berm</a> allows <br>
</p>
<ul>
<li>the level step element of raised barrier <br>
</li>
<li>raised element without a level element</li>
</ul>
<p>An earthwork raised element with a way on top seems to be an
embankment.</p>
<p>A earthwork raised element which has an armoured side seems to be
a revetment - I can see no use of this in OSM., but it is in many
books about castles and fortifications.<br>
</p>
<p>In my view earthworks in general could do with analysis to agree
terms and usage, they do occur in many places and are large
mappable features.<br>
