"If someone wants to map them they can. Not up to you or me to dictate what can go into OSM."
Sorry, but actually that's not the case. I can't decide to spam the database with an enormous number of entities without discussing with the local & global community. I regularly see reverts for much smaller things if they go against local or global customs and for a good reason. Please pay attention to my wording. I did not use the phrase "public property" on purpose. Schools buildings and training centers can also be private, but still serve public interest. Because OSM is a finite resource, we must constrain ourselves in what we add to it. We do not map the interiors of our own private houses over here (like corridors, doors, light bulbs, rugs, fridges, nails in the wall, individual bricks, etc), because the only person that can be of interest is me and my guests. I myself already know how to find these within my place, and I'd gladly show my guests where they can find what without referring to a global map. OpenStreetMap is a public map made for serving the public. What you need to think about is to who will this be useful to? I may decide to map how many bars are there on each fence, but if the only one in the world who needs or uses this information is me or my company, hence it is selfish to clutter such a global database with this. Surely as demand changes over time, mapping the number of bars may become the norm one day (similarly to how some count the number of steps in staircases, although not each individual step _yet_). Always keep in mind that a map is an abstraction - a reduction of reality to make it more manageable. The reduction is driven by demand and public utility, while keeping an eye on verifiable and maintainability as well. Let me link to a section of text has been recently deleted in a copy-edit, maybe out of mistake: "Places where internet access is only for members or private persons, and not offered to the general public. This includes your personal home DSL, LAN, WLAN, any internal networks of companies etc. Also internet access only for students (e.g., WLAN hotspots on the campus) should not be tagged, because this is not a public service and the people who have access rights already know about it. We know the internet is everywhere (or should be), but this tag's aim is to indicate locations where you can get online access just by paying some amount of money (or nothing), with no further efforts needed." https://wiki.openstreetmap.org/w/index.php?title=Key:internet_access&diff=1862346&oldid=1862337 So Telekom/FON users for example have an offline app that they can install to see the coverage, hence those who have access already know about it, while it is not useful for others to know (for example, most people I know don't have Telekom or FON at home, so they can't access). As FON is ran through end users at many places around the world, this also brings up problems with verifying ground truth. If I visit a given location and I don't see a FON there, was it fake, is my phone antenna too weak (maybe the mapper used an external one), or is the owner simply sleeping and having turned the router off for the night (for example via timers, many have this feature in their settings as well)? If we trusted the providers (who sometimes fake their maps to inflate their perceived user base), it would be a must to cooperate with them to properly maintain such a huge data set of millions of routers, otherwise it will bit rot pretty quickly due to churn and moving. This needs permission, an import and regular sync. I doubt that we have the capacity to keep it up to date by manual mapping - we can barely follow up on house numbers, still missing in most places with non-open governments. Maybe we could deploy a scanning app that automatically updates survey_date, but that sounds like a lot of work, especially that many people are against tagging BSSID (and that it can change due to various reasons). Another problem with usability is that customer premises equipment is usually ill placed, far from windows and on higher floors or deep within buildings, and hence may not be reliably accessible from the ground. They also limit the number of concurrent connections to a low number like 2-3, and if you found a lone AP on the map then you may not be able to gain access due to everyone singling it out. So mapping the subscribers can turn out to produce a lot of false positives. Public phone boxes with visible antennas, especially if they are marked is a bit different case and is considered verifiable, although they don't exist around here. But what about providers who only use home devices, like UPC, should we also endorse mapping that? Again, I'm all for mapping wireless stuff as it is so much fun and I do have private databases for these as well, but the above is the interpretation of what aspects you need to keep in mind from the side of the community when mapping things within OpenStreetMap. I think I've also read a few mailing list threads, forum topics, FAQ entries and whatnot in the past about just this, just ping me if you'd like to refer to some of them and I'll try to find them for you. So to sum it up, you may map whatever you desire until you follow (additional to the usual best practices): * use abstraction * honor public interest * allow maintainability * don't clash with others * don't disappoint users * discuss with the community On Mon, Dec 30, 2019 at 10:40 PM Warin <61sundow...@gmail.com> wrote: > > On 30/12/19 21:31, bkil wrote: > > We have similar services to those, but I wouldn't map those.
