<div dir="ltr">This topic gets revisited from time to time and as you'll see, opinions differ about how to tag these surfaces. For your example, I would tag it as surface=gravel and tracktype=grade1. You can also include a smoothness=* tag to further characterize its drivability. <div><br></div><div>I have never seen a highway for automotive or truck use that used railroad ballast for a surface.

<pre class="m_-4024370229610753584k9mail"><div><div class="h5">I recently bought a gravel bicycle to ride on the many gravel roads in<br>Kansas. Like this one:<br><a href="https://www.mapillary.com/app/?pKey=nYO4JI46L0SWzNAQlLT4kA&focus=photo" target="_blank">https://www.mapillary.com/app/<wbr>?pKey=nYO4JI46L0SWzNAQlLT4kA&<wbr>focus=photo</a><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 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 a<br>big difference between the two when it comes to bicycle riding.<br>Railroad ballast is bone jarring and flat tire inducing whereas 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=photo" target="_blank">https://www.mapillary.com/app/<wbr>?pKey=iQNqP-dfQ-Rm6AD9REMsgQ&<wbr>focus=photo</a><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" target="_blank">https://wiki.openstreetmap.<wbr>org/wiki/Key:surface</a><br><br>Toby<br><br><hr><br></div></div><span class="">Talk-us mailing list<br><a href="mailto:Talk-us@openstreetmap.org" target="_blank">Talk-us@openstreetmap.org</a><br><a href="https://lists.openstreetmap.org/listinfo/talk-us" target="_blank">https://lists.openstreetmap.<wbr>org/listinfo/talk-us</a><br></span></pre></blockquote></div></div><br>______________________________<wbr>_________________<br>
