width, which is only tagged on 3.5% of

in another forum. For a forest path, would you
say width is measured as the actual tread on
the ground only? For a runner and MTB cyclist
that would make sense, but for a hiker with a
big backpack a width of 0.3 m may mean they
think it's not possible to walk there. </div>

<div class="">Width is, at least in my area, going to be a hard
issue.</div>
<div class=""><br class="">
</div>
<div class="">For background, I have been volunteering on trail
maintenance teams in a near by designated wilderness area where
the vegetation is largely chaparral (scrub) and this has shaped
my opinion.</div>
<div class=""><br class="">
</div>
<div class="">Many of our trails were originally ranch access
roads (highway=track) and in some short sections here and there
where things were scraped to bedrock the trails remains that
wide, maybe 3m. However the overwhelming majority of the trail
mileage have been overgrown to the point of being impassible on
foot without constant maintenance. Our standard for maintaining
a section of trail is that the tread (where your foot meets the
ground) should be a minimum of 0.5m and that the width at
shoulder level should be 2m. In the occasional areas where we
have trees, etc., we strive for about 3m vertical clearance so
that an equestrian can get through. Being a designated
wilderness, no power tools or wheeled vehicles are allowed so
access is by hiking and work is performed with hand tools.</div>
<div class=""><br class="">
</div>
<div class="">If you look to motor vehicle roads, width is of the
traveled way, not of the right of way nor of the way cleared of
vegetation (i.e. side drainage or shoulders, etc.). From that
point of view, a trail width should likely be the tread width.
But as noted by Daniel, a hiker with a big pack might be more
interested in the width at pack/shoulder level (“loading
gauge”).</div>
<div class=""><br class="">
</div>
<div class="">The issues in mapping trail width in my area
include:</div>
<div class="">
<ol class="">
<li class="">Chaparral is fast growing. So that 0.5m/2m width
trail we fixed today will shrink each rainy season and
without maintenance is likely to become impassible in maybe
5 years time.</li>
<li class="">Trail maintenance teams are lucky to be able to
clean up 2km of trail in a session. So it takes multiple
sessions to keep a typical trail maintained and for any
given trail those are sessions occur over a number of years
(we target areas where things are worst).</li>
</ol>
</div>
<div class="">The result is that trail width is highly variable
both over the length of a trail and over time. If mapped in high
detail, the width you map this hiking season will be wrong next
year. Heck, it might even be wrong next month depending on what
month of the year your did your survey.</div>
<div class=""><br class="">
</div>
<div class="">For what it is worth, I don’t usually tag the width
of the trails. Mostly for the above reasons: To do it properly
I’d have to be taking very detailed field notes and have to
re-survey each trail at least once a year. And even if I did
that, when I look at the typical data consumer I see that they
usually have stale OSM data so any attempt to keep OSM up to the
day correct on field conditions wouldn’t be very useful anyway.</div>
