<html><head></head><body>Keep in mind that OSM apparently uses "compacted" to refer to macadamized roads, which is a specific process for building roads. <br>
<br>
Maybe they wiki should be updated to say that roads with loose pieces of gravel scattered around but a hardened underlying surface is compacted, not gravel?<br>

Like this one:<br> <a href="https://www.mapillary.com/app/?pKey=nYO4JI46L0SWzNAQlLT4kA&focus=phot">https://www.mapillary.com/app/?pKey=nYO4JI46L0SWzNAQlLT4kA&focus=phot</a><br> o<br> <br> First question: What would you call this road? Obviously I am calling<br> it a "gravel road" but a couple of people have said they would call<br> it<br> a "dirt road" so I'm curious if there are any other common terms to<br> describe this type of road in different regions of the US.<br> <br> Second question: How would you tag this road? There is a<br> surface=gravel tag that is in pretty common usage in Kansas and<br> neighboring states. However looking at the wiki page for the surface<br> tag[1], this is not wiki-correct. According to that page<br> surface=gravel is to be used for large rocks (4-8cm) that are laid<br> down loosely like those typically used as ballast on railroad beds. I<br> believe The Mapillary picture I linked to would be considered<br> surface=compacted according to the wiki because the rocks are much<br> smaller and the surface is stabilized with a binding agent. There is<br> a<br> big difference between the two when it comes to bicycle riding.<br> Railroad ballast is bone jarring and flat tire inducing whereas<br> gravel<br> roads are pretty manageable on the right kind of bike.<br> <br> But If you call something a "gravel road" and there is a "gravel"<br> option in the editor preset for the surface tag, people are going to<br> choose the gravel option and not look for "compacted" since that is<br> not a common term here. I assume it is a more common term in the UK<br> and that is why it is used in OSM.<br> <br> And lastly there are trails that are surfaced with a similar material<br> but crushed to a smaller size like here:<br> <a href="https://www.mapillary.com/app/?pKey=iQNqP-dfQ-Rm6AD9REMsgQ&focus=phot">https://www.mapillary.com/app/?pKey=iQNqP-dfQ-Rm6AD9REMsgQ&focus=phot</a><br> o<br> <br> I'm trying to decide if that is better as surface=compacted or<br> surface=fine_gravel although fine_gravel seems to be a slightly<br> different process from what I see on the wiki.<br> <br> Maybe this should be directed at the tagging list but I thought I<br> would get thoughts from the US community since we seem to be the ones<br> using the tag incorrectly (according to the wiki)<br> <br> [1] <a href="https://wiki.openstreetmap.org/wiki/Key:surface">https://wiki.openstreetmap.org/wiki/Key:surface</a><br> <br> Toby<br> <br><hr><br> Talk-us mailing list<br> Talk-us@openstreetmap.org<br> <a href="https://lists.openstreetmap.org/listinfo/talk-us">https://lists.openstreetmap.org/listinfo/talk-us</a><br></blockquote><br><hr><br>Talk-us mailing list<br>Talk-us@openstreetmap.org<br><a href="https://lists.openstreetmap.org/listinfo/talk-us">https://lists.openstreetmap.org/listinfo/talk-us</a><br></pre></blockquote></div></body></html>
