I would be careful here - 'dirt' is essentially a very vague term which<br>
probably originates from the concept of 'dirt roads' here. 'Soil' in<br>
the other hand is fairly precise, see<br>
<br>
<a href="https://en.wikipedia.org/wiki/Soil" rel="noreferrer" target="_blank">https://en.wikipedia.org/wiki/Soil</a><br>
<br></span>
Only parts of the earth surface are actually covered by soil so if a way<br>
is correctly tagged with surface=soil (and i don't know if that is the<br>
case for the 400 cases you mention) this is something specific and<br>
potentially useful and should not be degraded by turning it into<br>
something as vague as surface=dirt.<span class=""><br>
<br>
In general i think surface=ground is the most sensible tag for tagging<br>
ways that are just established somewhere without notible construction<br>
work when you can't be more specific - it implies that the way surface<br></span>
is essentially the ground there in its natural state. surface=dirt<br>
OTOH can mean anything from the remaining tracks of a car driving<br>
across a wayless area to a solidly built gravel road.<br>

Agreed.<br>
<br>
Between soil, dirt, ground, earth, and mud, dirt is the worst defined<br>
of the lot, and I would hesitate to use it for anything.<span class=""><br>
<br>
If you do want to consolidate tags, "earth" is a much better synonym<br>
of "soil" and you should probably use that instead.<br>
<br></span>
"Ground" is earth+rocks+sometimes_vegetation. "mud" is earth with a<br>
lot of water and clay.<br>

My proposal in case someone wants to help beginners with the surface tag:<br>
*Illustrate* the surface hierarchy somewhere in the OSM wiki (e.g. at <<a href="http://wiki.openstreetmap.org/wiki/Key:surface" rel="noreferrer" target="_blank">http://wiki.openstreetmap.org/wiki/Key:surface</a>>).<br>
Right now the hierarcy is not illustrated, it is just in two tables (unpaved and paved). An illustration works better, and the hierarchy can have more than two levels.<br>
<br>
Place surface=paved and surface=unpaved at the top, surface=ground etc on the next level and probably surface=wood, clay, mud, etc. at the bottom.<span class="HOEnZb"><font color="#888888"><br>
