<div>I had assumed for years that the direction pointing
upwards was a commonly agreed on standard, being
myself an architect I hadn't expected this to be
questionable, but as I got so much flak from people
insisting on the other way round, I now am adding the
tag incline=up to all steps. This way you remove any
ambiguity and introduce some further stability also
for cases where the way direction gets inverted. No
need for any (IMHO unachievable) decision any more ;-)<br>

<div>We need to have this standardized - just like waterways and
walls - ascent or descent should be implicit in path direction. </div>

</div>
<div>There should be a standardized.</div>
<div><br>
</div>
<div>If that is impossible, then at least the ascent/descent tags
should be standardized- </div>
<div><br>
</div>
<div>Ascent=yes / reverse or -1 or however the one way tag works,
or the direction=ascent /descent or incline or something - just
anything that's standardized. <br>

The thing that attracted my attention to this was the direction of
the way not being used the same way as standard practice .. and as
documented in the international and national standards. <br>
<br>
Within OSM .. I've checked
<a class="moz-txt-link-freetext" href="http://wiki.openstreetmap.org/wiki/Key:incline">http://wiki.openstreetmap.org/wiki/Key:incline</a> - that sets a
'standard' for the incline direction. <br>
<br>
I'm tempted to simply add the information to the wiki for steps. The
past discussion on this topic is from years ago. I'll think about
it. <br>

<div class="gmail_extra">There is the area relation proposal
which deals explicitly with this (type=area), but it isn't
supported by any data consumer AFAIK.<br>
Please note that you have to create a new relation for
every continuous part of stairs (i.e. the stair landings
are not included).<br>

Humm slack. That is a Draft proposal from December 2009 ... I'll
contact the proposer! Try to advance teh steps bit as I understand
that need. <br>

<div>Is that something I can do in iD? I'll have to read up about
relations. I've only ever edited a couple, and that didn't
exactly go well. </div>
