Is it characterizable, identifiable? Is there a formal border around it? Does everybody agree? All of those seem difficult "to be (true) simultaneously" (as I understand what is meant when somebody suggests "avoid that area because of, or unless..."), so I fall on the side of "if no identifiable hazard, then no specific tag." In short, I think we agree: too subjective. Even WITH a consensus of local mappers, I don't believe it stands tall enough unless it rises to "true" for all three of those questions. And likely some more I haven't typed here, too. (Others might). Specific hazards, that are characterizable, identifiable, confined to a well-defined area and widely agreed upon? Yes, Earth likely has some of those. A node tagged hazard=* might work well. This feels like a rough sketch only (still) despite getting shot down repeatedly as an unfocused or wholly wrong idea.

This has the potential to rear its head in a really classist, and varying ranges of racist, ways as well. For example, go post on Reddit on any given city's subreddit, and ask "I'm moving to ___, what parts of town should I avoid?" Fair warning, try this for a city you're familiar with, and be prepared to die a little inside with the answers you get. Personally, I'm more likely to consider middle-class suburbia a no-go area because large parking lots make it easy for car prowlers no matter how many police are on the streets, transit coverage tends to be iffy before morning and after evening peak commuter hours, and 5+-lane-wide boulevards tend to be not-safe-for-life if you need to traverse them without using a car.

Re: [OSM-talk] no-go-areas
Right, Martin; thanks. Joseph and I discussed off-list there is some conflation of tags from hazard=* which intersect well with at least one or two existing military=* tag values. So, yes, there is some overlap with existing tag (natural=cliff, too). I have read our hazard wiki (thanks for the ref) and also mentioned to Joseph that hazard=* seems (in addition to being 12 years old and ripe for an update) a bit too much "car and driver" oriented. For example, if a sign warns of "moose crossing" or "children often play near this roadway here" OK, put that sign on a node onto or next to the highway. In addition to chasm going away, radioactive hazards (there's ionizing radiation, RF energy...) and that there are even places where you wouldn't want to be standing during a thunderstorm as they are struck by lightning repeatedly (yes, really: seems there might be one or two in Texas and Canada) there are really verifiable "hazard=yes" places (that are not subjective and quite verifiable) where a node and a brief mention might be a real thing we could very well want to add to our map. Nudge forward, I don't have massive passion or energy to go much further with it, next up, please! (Yeah). What a great project, OSM. (I truly mean that).

Re: [OSM-talk] no-go-areas
I've certainly tagged plenty of natural=cliff (and I'm not done yet), there's lots of them around me. So perhaps hazard=chasm could deprecate as one value of the proposed key hazard, deferring to natural=cliff. Still, there are plenty of objective, not-going-away-soon, not-politically-sensitive hazards on Earth. We should map and render them, but to do so, we might resurrect a more-modern version of the hazard tag proposal. Or anything else that would do the job. These do seem like good, smart things to map.

Re: [OSM-talk] no-go-areas
Really? Actual, real-life hazards like [chasm, radiation, rock_slide, minefield...] are not worthy of that tag on a node and some Carto-code to toss up a triangle-! icon on our map? Where's the harm? (Literally). Perhaps we implement these without including (or specifically EXcluding) the more "sensitive" ones which are considered "subjective." We can't be "too subjective" if we aren't subjective at all. But, explicitly objective hazards do seem worthy to map. Many (most?) like radiation, live minefields, military bombing areas, sharp bluffs / cliffs are not transient at all and would likely remain as long-term hazards. I think we should revisit this rather than dismiss it matter-of-factly as "oh, that hazard thing that pops its head up every year or so."

Re: [OSM-talk] no-go-areas
This question rears its head every year or so & the conclusions are always the same: Far too subjective, Far too transient. Best left to be shown as an overlay by local authorities.

Re: [OSM-talk] no-go-areas
As a long-time OSMer, I offer perspective on two "dangerous areas" near me, one past, one present. On my university campus (University of California) there WAS an area in a meadow which was grazed by cattle (both from the original landuse from a century ago and presently, as these meadows are grazed by cattle even today, at a university of tens of thousands of students). A decade and longer ago, there was a swale (low-lying area) which I believe was human-converted into a sort of reservoir for watering cattle, but it had steep sides, was quite deep and could be impossible for humans or cattle to escape if they fell into it, especially when empty / dry. Not by me, but this was marked on OSM as a "no go area," which I always found curious, as that wasn't an explicitly defined tag. I'm nearly certain that today, this dangerous area has been "remedied" (filled in with dirt) and no longer exists as a hazard on campus. In OSM, there is no longer anything (node, way) in the area to tag as such; it has effectively disappeared from both the real world and our map. Also near me is a "beach" (it sort of is, sort of isn't) which is a dangerous place to ocean-swim, it is known locally as the "Toilet Bowl" as it has nasty churning surf and undertow currents which I believe have drowned at least one person. When I heard local news that such a drowning occurred yet again, I endeavored to tag a node there with name=Toilet Bowl (dangerous area, no swimming) + swimming=no + hazard=yes. (Yes, I know that violates "name is name only"). Also, there isn't a "physical" tag (like natural=beach, as that is unusual, though not wholly wrong, on a node). Yet I couldn't help but feel that hazard=yes, a "draft / underway proposal" (since 2007?! really?) is insufficient: the value "yes" isn't documented in the proposal, and others listed there, like chasm, radiation, rock_slide, minefield, playing_children... didn't fit a dangerous swimming area. Plus, the hazard tag doesn't render (a triangle with exclamation point might be a good starting icon). I believe OSM needs better, explicit tagging to identify dangerous, hazardous areas, and Carto should render these. There are many different kinds of these, from those I just noted, to "high-crime area" and what others might consider sensitive or political. (We shouldn't be afraid to say that an explicit hazard exists if one does). A proposal that seems to have gotten stuck for 12 years seems it's a good starting point, can it be resurrected? OSM mapping these would be another welcome feature in our map, as I know of no other general-purpose map (that IS how many use OSM) which identifies these sorts of "everyday" hazards. Think about it: a hazardous situation might find YOU one day, and you might be very glad you saw this on a map beforehand so you could avoid it.

Re: [OSM-talk] no-go-areas
Wouldn't that just be a crime map or a bias towards areas vs others.
