Re: [HOT] Roads, driving & Wiki | Re: Thank you from MSF!
I change these things from time to time. :)

But my question is still why the organizations that pretend to use OSM
data don't help with troubleshooting.

Wikipedia's goal is a "Neutral Point of View", OSM's is "No
Point of View", to only store objective things, to never store
subjective things. "This road is not passable by a car" depends a lot on
the type of car! A 4x4 Land Rover can drive on roads a Porsche sports
car can't. We tag _legal_ restrictions on roads ("Cars are not
legally permitted to drive here"), since everyone agrees on that.
There is a `tracktype` key (
https://wiki.openstreetmap.org/wiki/Key:tracktype ) with 5 values for
how smooth/wellmaintained the road/track is. You can also map the
`surface` and `width` of roads. There are some less popular tags that
might be useful to you like `4wd_only=yes/no`, `sac_scale` or
`mtb:scale`.
Is there a reason for that or will you change them later?
OSM is a map made by everyone, including you (if you want). Don't be

Re: [HOT] Regional highway tag values | Re: Thank you from MSF!
Thanks Rory
There are somegeneric guidelines on how to do tagging, e.g.
Highway Tag -OpenStreetMap Wiki
HighwayTag Africa - OpenStreetMap Wiki
and additionally there may be somemore country-specific guidelines (I’ve found
the following so far, some as aresult of replies from contributors over the
past week or so):
HighwayTag Afghanistan - OpenStreetMap Wiki
HighwayTag East Africa Tagging - OpenStreetMap Wiki
HighwayTag Ghana Road Network - OpenStreetMap Wiki
HighwayTag India:- OpenStreetMap Wiki
HighwayTag Malawi - OpenStreetMap Wiki
HighwayTag Namibia - OpenStreetMap Wiki
Highway TagNepal/Roads - OpenStreetMap Wiki
HighwayTag Philippines Guidelines - OpenStreetMap Wiki
HighwayTag South Africa - OpenStreetMap Wiki
The following list contains anadditional 30 or so countries (some of which are
included above, but not all),so there doesn’t seem to be a definitive list of
how countries tag their ownclassifications:
https://wiki.openstreetmap.org/wiki/Tagging
They’re all similar, but can besubtly different.
In any event, I haven’t found asingle, definitive page of how countries tag
their highways yet, but amconsolidating one!

That is certainly something that can be confusing at first. Although OSM
tags/keys/values are written in English ("highway"), it's better to not
"read" them and pretend they are just opaque computer codes, which you
'translate' into your own local language, or region specific thing.
Rather than reading highway=trunk, pretend it says uvtujnl=gehax. In the
USA "highway" means something different, so it can be confusing, but if
you just think "What does uvtujnl mean in my country/region?", A British
person translates it as "highway", an American "street", a German
"Straße" etc. Then, rather than seeing "trunk", see "gehax", and ask
what that means in your language/place.
The OSM wiki has a big list of how to translate each highway value into
regional equivalents:
https://wiki.openstreetmap.org/wiki/Highway:International_equivalence
In Ireland, we have highway=trunk for "National Primary",
highway=primary for "National Secondary", highway=secondary "Regional",
highway=tertiary "(low numbered) Local", and highway=unclassified for
the rest.
The local community for each country should decide on such a
"translation", and then use that. Write that in the wiki and talk to
OSMers to tell them. (I wonder if iD's regional specific translations
might be useful here (e.g. to translate "highway=trunk" in en_IE to
"National Primary"... 樂)
I hope that helps.

Welcome to OSM!
With regards to OSM, one issue is that the tag in OSM is never
quite the same as the official definition of the country. For example,
the highway tag:
https://wiki.openstreetmap.org/wiki/Key:highway
uses "Motorway", "Trunk", "Primary", "Secondary" etc. while a national

"Local" etc.
