<p>In UK English (not sure about other dialects!) "depth" is often used in a horizontal sense. The depth of a cupboard or a shelf for example, or the depth of a hole you have drilled. The depth of an adit would make perfect sense to me - indicating how far it penetrates into the substrate. If it is straight, it is equal to the length; if there corners, the length may be greater than the depth.</p>

<div dir="ltr">Sounds reasonable to me. If it's horizontal or near-horizontal, depth makes no sense.<br />

<div>According to <a href="https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dadit">https://wiki.openstreetmap.<wbr />org/wiki/Tag:man_made%3Dadit</a> the tag "depth" should be used for the length of an adit (horizontal mine entrance). According to wiki discussion, people seem to agree that "length" is a better tag for this, as "depth" is used to indicate how deep (vertically) something is.<br /><br /></div>
<div>Any complaints or agreeing voices for this change?</div>
