<div class="moz-cite-prefix">Hello Kevin,<br>
<br>
the wiki is always a good resource. There are project pages for
many countries which contain tagging guidelines inluding a
translation from official classification to OSM classification,
e.g.:<br>
<br>
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/WikiProject_India">https://wiki.openstreetmap.org/wiki/WikiProject_India</a> =>
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/India:Tags/Highway">https://wiki.openstreetmap.org/wiki/India:Tags/Highway</a><br>
<br>
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/WikiProject_South_Africa">https://wiki.openstreetmap.org/wiki/WikiProject_South_Africa</a>
=>
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/South_African_Tagging_Guidelines">https://wiki.openstreetmap.org/wiki/South_African_Tagging_Guidelines</a><br>
<br>
For many countries covered by HOT projects such pages do not exist
which led to the creation of a few guidelines by HOT already
mentioned in this thread:<br>

<br>
Any modifications should best be discussed (and finally
documented) on these pages.<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>
</div>
<div>Regards, Kevin McPherson<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 clear="none">
