<div dir="ltr">In OSM we map what is actually on the ground, not what someone would like to be on the ground. We are like "spatial journalists", and like journalists, we report (map) the facts (does the US Government try to tell the NY Times what to publish? Only in extreme circumstances.). There will always be those who claim that the "facts are dangerous" and therefore should not be reported, and I am sure one can find isolated cases where this is true (this is not limited to trails or OSM, it seems that every few months there is a story of someone in their Honda Civic (e.g.) taking a "shortcut" that appears on their navigation app as a 4x4 road that only a rock crawler could traverse - no substitute for common sense). But more often than not, the danger is to the particular group that desires these facts be suppressed.<div><br></div><div>If there really is a problem, land managers can post signs "no off trail use", "not a trail", etc., and enforce such. <div><br></div><div>I have talked to a number of search and rescue people that actually use OSM because it does contain so called "social trails." It may also help legal land users remain safe. A few years ago there were a number of deaths on Capitol Peak in Colorado because hikers had gotten off route. I and another mapper added the "trail" to the peak to OSM (note, not NPS land). <br><div><br></div><div>In addition, my experience with the NPS trail data is that it is often in error, and they refuse to fix it, and even acknowledge that it could be wrong.</div></div><div><br></div><div>Finally, removing this valuable content from OSM will not achieve the ends the NPS and others want to achieve as it appears independently in a number of apps.</div><div><br></div><div>Mike</div><div><br></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Oct 8, 2021 at 10:30 AM Zeke Farwell <<a href="mailto:ezekielf@gmail.com">ezekielf@gmail.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"><div dir="ltr"><div><span dir="auto">Recently a number of us attended <span dir="auto">the "Mappy Hour" presentation<span dir="auto"> "<a rel="nofollow" href="https://www.youtube.com/watch?v=TXXGkBVJK-o" target="_blank">Trails in OpenStreetMap</a>"</span> by</span> Keri Nelson of the National Park Service.
