Dear Kevin,
<div><br>
</div>
<div>In many countries, the country designations are mapped to the
OSM conventions and then the Main, District, or Local to which
you allude could be a part of the ref/number. Afghanistan has a
pretty simple process to go from from OSM to national data (<a
href="https://wiki.openstreetmap.org/wiki/Highway_Tag_Afghanistan"
moz-do-not-send="true">https://wiki.openstreetmap.org/wiki/Highway_Tag_Afghanistan</a>)
please note that this highway tag list was adapted from the fine
work done for <a
href="https://wiki.openstreetmap.org/wiki/Highway_Tag_Africa"
moz-do-not-send="true">https://wiki.openstreetmap.org/wiki/Highway_Tag_Africa</a>.</div>
<div><br>
</div>
<div>In Afghanistan, the government knows that OSM secondary roads
are “district roads” and the ref number reflects that, e.g.
D320781 (Secondary) and NH1010 (Trunk), Afghanistan doesn’t use
the motorway designation from OSM. If they need to change the
tag after downloading, a simple if/than script can make the
adjustment in a couple minutes.</div>
<div><br>
</div>
<div>I’m happy to learn more how other folks have tackled this
issue.<br>

<div>Dear all, I am new to this HOT interface on OSM,
but joined last week, and interested in road
classification in OSM. This is my first posting, and
first time I have engaged with anyone on OSM, so am
still getting up to speed.<br>
</div>
<div><br>
</div>
<div>"Road Classification" is an important topic for
roads agencies, it helps define the funding and
prioritisation for development and maintenance of the
road network in a country.</div>
<div><br>
</div>
<div>With regards to OSM, one issue is that the
<highway> tag in OSM is never quite the same as
the official definition of the country. For example,
the highway tag:<br>
</div>
<div><br>
</div>
<div><a
href="https://wiki.openstreetmap.org/wiki/Key:highway"
rel="nofollow" target="_blank"
moz-do-not-send="true">https://wiki.openstreetmap.org/wiki/Key:highway</a></div>
<div><br>
</div>
<div>uses "Motorway", "Trunk", "Primary", "Secondary"
etc. while a national roads agency might use other
terminology such as "Main", "District", "Local" etc.
<br>
</div>
<div><br>
</div>
<div>What this means is that the road network
classification in OSM is never quite the same as that
used by the Roads Agency, and there are discrepancies
between the "official" data of the roads agency, and
the OSM definition. This causes confusion to anyone
who wants accurate mapping.<br>
</div>
<div><br>
</div>
<div>As part of my work, I am trying to encourage Roads
Agencies to review OSM mapping, to compare with their
official definitions, and to update OSM based on their
own records. However, the differences in the
classification terminologies are a barrier to this.
Every country potentially has a different
classification system. We have been discussing
internally that an extra "layer" on top of OSM might
be a way forward, but that is an overhead and requires
extra cost and administration.</div>
<div><br>
</div>
<div>Would be grateful for anyone's views on this.</div>
<div><br>

<p>My point this time is not the classification
of a few roads. What I learn from this, is
that our data is processed and reviewed again.
If a mapping error is detected by local staff,
it will most likely only be reported to their
own mapping department. It will also only be
fixed locally. We as mappers or validators
will never learn from this process. All errors
will remain in the OSM Database. That might be
understandable in an emergency situation like
now. But without direct feedback from map
users we will never improve. We should also
demand that more local knowledge will be
shared with OSM. A simple thank you is not
enough.</p>

both get updated from time to time. As a
general rule of thumb I tag highways between
settlements as unclassified not track, I
leave it to the local mappers to say if it
is a higher classification. Occasionally
I'll tag as high as tertiary. Normally I
leave the tags alone but have been known to
retag motorways between two small
settlements as unclassified.<br clear="none">
<br clear="none">
I think step one is to get something
mapped. Step two is correct it and with
lots of new mappers with different ideas
we'll always see some problems.<br

Different mappers judge different how to
tag a highway. Out of my own experience
lots of mappers (and validators) struggle
with how to tag a highway. Looking to the
importance, the routing, and the width of
the highway, which is hard to measure from
a satellite image, we have to decide. A
big number of new mappers are joining us
and have different ideas (nor no idea at
all) how to tag a highway. I've seen
taggings as secondary highway as a
connection to 2 hamlets and so on. So we
try to tag as good as possible, but often
it is a (calculated)guess which tag is
relevant. Take also in account that there
is a huge time pressure on these disaster
mapping projects, so sometimes you accept
the tagging as they were made. When there
is no time pressure you can take a look to
each highway and decide. <br clear="none">
I hope you get an understanding how we
have to deal with this subject. <br
