<div dir="ltr"><div>By the way, I checked with some people in the OSM Japan community, and it looks like they currently encourage using relations for representing prefectural or national road status -- for example, there is a national route 197 that includes a ferry route (<a href="https://www.openstreetmap.org/relation/65441">https://www.openstreetmap.org/relation/65441</a>), which obviously wouldn't be able to be mapped as highway=trunk. (There was some discussion about this on the Japanese mailing list in 2013: <a href="https://lists.openstreetmap.org/pipermail/talk-ja/2013-May/007340.html">https://lists.openstreetmap.org/pipermail/talk-ja/2013-May/007340.html</a> )<div><br></div><div>I think this particular case may be a misunderstanding of current local mapping rules?</div><div>I agree that there should be standards for well-known and heavily used tags (for example, a mountain path shouldn't be able to be mapped as a highway=primary or secondary, or a more extreme case of a ferry route being tagged as highway=primary), but maybe encouraging / requiring more open discussion and/or authoritative documentation on local rules would be helpful in reducing misunderstandings like these.<br class="gmail-Apple-interchange-newline"></div></div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">Keitaroh Kobayashi<div><a href="mailto:keita@kbys.me" target="_blank">keita@kbys.me</a></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Oct 20, 2022 at 7:50 AM <<a href="mailto:osm.sanspourriel@spamgourmet.com">osm.sanspourriel@spamgourmet.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>> Japan has local rules that _require_ a very rough mountain
path near me, impassable by any vehicle</p>
<p>In France we came recently to "départementales" ("roads" managed
by the Département (= Prefecture in Japan) mapped as track or even
path.</p>
<p>This was correct indeed: for historical or obscure reasons they
were probably roads, aren't any more and haven't been given to the
commune for local management.</p>
<p>So on the map you see the reference of the road (D *, not C *),
so the "status" but the description of the way is made according
to OSM standard.</p>
<p>The way to go for Japan? Thanks to the ref they will be able to
map the Japanese way and others will do it the usual way, having a
normal map.</p>
<p>So there is NO need for Japan to misuse highway tags, they can
map properly and have their funny/traditional maps based on OSM.<br>
