<div>If I were to design the ideal tag for
Australia, it would be something like:</div>
<div><br>
</div>
<div>technicality=0-3</div>
<div><br>
</div>
<div>0. Well formed, even surface (could almost
walk it blindfolded).</div>
<div>1. Uneven surface, trip hazards from rocks,
tree roots etc.</div>
<div>2. Large steps, long steps, may be slippery
(wet, mossy or loose surface), likely need to
use hands for balance, low or tight sections
that you need to crouch</div>
<div>3. Short sections where you're almost pulling
your whole body weight with your arms (with or
without a hand rope). Highest level short of
proper rock climbing.<br>
</div>
</div>
</div>

<div><br>
</div>
<div>Nicely thought out!</div>
<div><br>
</div>
<div>Would you also add in River Crossing, possibly as
3, pushing climbing up to 4?</div>
</div>
</div>

<div><br>
</div>
<div>Good point. River crossings are important to consider and
do affect the overall technicality of the walk. I would
consider river crossings fitting into level 2, as they are
similar (large steps, long steps, slippery, likely need
hands for balance).</div>
<div><br>
</div>
<div>I would support a new tag to describe each river
crossing, we have already:</div>
<div><br>
</div>
<div>- bridge=yes (where you can walk over)</div>
<div>- tunnel=culvert (when the waterway goes under the
walkway)</div>
<div>- ford=stepping_stones (creek crossing, but stepping
stones exist so you won't usually get wet)<br>
</div>
<div>
<div>- ford=yes (which on a highway=footway/path is saying
it's a creek/river crossing where the waterway flows over
the path or the path goes through the river/creek)</div>
<br class="gmail-Apple-interchange-newline">
</div>
<div>Obviously river conditions change, but I think it's
useful to tag what's usually the case:</div>
<div><br>
</div>
</div>
</div>

0 creek/river crossing where there is usually no water. <br>

<div>1. creek crossing where generall the water level is so
low that you won't have water ingress in your shoes</div>
<div>2. creek crossing where your body will stay dry but
you'll want to take your shoes off if you prefer to keep
them dry</div>
<div>3. river crossing where your body will get wet, may have
a rope to help you cross, but you can wade through the water
and won't usually need to swim</div>
<div>4. river crossing where you'll need to swim across</div>
<div><br>
</div>
<div>I don't like using numbers as values as they aren't self
explanatory but I can't think of short terms you could use
for tag values.</div>
<div><br>
</div>
<div>I've always thought of ford as more being a road was
built and the watercourse flows over that road, whereas
walking it's more usually the track stops/ends at either end
and you're going through the watercourse, maybe it's just
semantics though. <br>

<p>Some 'fords' have pipes under them to take the usual water flow
off the road/path. I still map them as 'fords'.. as that is what
they resemble. <br>

<div>In the Australian context there's also
probably remoteness measure, but these would be
too subjective to tag on individual ways and
probably could simply be a function of distance
to nearest facilities.</div>
<div><br>
</div>
<div>0. urban bushwalks</div>
<div>1. not too remote, mostly day walks</div>

<p>I would think something on the ease of communication?</p>
<p>1. Good cell phone coverage (it does not matter which provider
when calling 000/112)</p>
<p>2 Cell phone coverage on the peaks only, the peaks being
frequent. <br>
</p>
<p>3 PLB advised as cell phone coverage is too sparse or non
existent. <br>

<div>How about water? In an Oz context, heat / thirst is
often a bigger problem than cold, so would you have
some form of tag for availability of water resupply?
(apart from just having rivers / streams mapped)<br>
</div>
</div>

</blockquote>
<div><br>
</div>
<div>Yes that's part of it, but I think it's best to keep the
tag as narrow and possible and not mix in orthogonal
measures. You could have a well formed even surface walk but
very remote and you need supplies, likewise you could have a
walk which needs pulling your body weight up, but you don't
need any supplies.</div>
