Re: [Talk-us] Moving historic railroad ways from OSM to OpenHistoricalMap
Here in Kansas we have very many abandoned railways (and many pickup trucks to replace them) that are turned into trails or paved over and still visible. I would say if there is any sign of them left to keep the information in some way.

The deletionists have migrated from Wikipedia to here. How do we stop them? Isn't it bad enough that the main map doesn't render abandoned railroads anymore? Now he has to be deleting them? Exactly who are they hurting by keeping them in the database? How about doing the *right* thing, and mark them as railway=razed or railway=dismantled (I use the latter but I've seen the former). > As the premise of OSM is to only map ground-verifiable features > (other than certain boundaries), I didn't want to argue with him, Oh, I'd be HAPPY to argue with him. I can point to all sorts of ways to tell that a railroad used to go through, that most people don't know about. Certain types of fenceposts, property lines that line up with nothing but the railbed, back yards that are "too deep", roads that are S-shaped for no obvious reason, houses that line up with nothing but the railbed.

That doesn't make *any* sense, Frederik. The signs are only there because the railroad was there. We are not making a map as a random collection of fencelines, and embankments and cuts and shadows-on-farmers-fields and trees-on-stone-walls. That's complete nonsense. There *used* to be a railroad there and that's *why* there's a fenceline and embankment etc. Maps are for understanding, not collections of unrelated elements. I don't have an awful lot of use of OpenHistoricalMap because it's a faux-layer. OSM doesn't have layers (for better or worse), and trying to create them by using a completely separate database is a purposeful attempt to #FAIL. Since my goal isn't failure, but instead success, we're going to keep dismantled railways in OSM. -- --my blog is athttp://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog ___ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us

Minh Nguyen writes: > On the ground, meanwhile, you'd tend to find no trespassing signs > on railbanked ROWs, no? Railbanked railroads should always be tagged as railway=abandoned. The whole point is that they *haven't* been dismantled or razed or destroyed or whatever word you want to use for a railway that doesn't exist anymore. Legally, it's still a railroad right-of-way whether it has tracks or not. Even if a farmer has plowed it up, or someone has built a house on it, it's still legally a railroad right-of-way. Some dude in Whiteport, NY (right next to Whiteport School), thought that the railroad behind his house had been dismantled / destroyed / razed / whatever. He cut down the brush, and started mowing it. Eventually he put an above-ground swimming pool on it. Poor bastard now has a fence about five feet behind his house keeping him off the railroad right-of-way, now part of the Wallkill Valley Trail. -- --my blog is athttp://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog ___ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us

There are many kinds of public domain maps whose republication needs no license. For example, in the US all maps published before the magic date, whatever year it is we're up to now.

Re: [Talk-us] Moving historic railroad ways from OSM to OpenHistoricalMap
I understand keeping a feature in OSM if there is a remnant of the railroad, but there are areas where everything has been replatted, regraded and redeveloped, yet there is still a "razed" feature in OSM (for one small example, see https://www.openstreetmap.org/edit?#map=16/38.8663/-94.7943). This seems like a good candidate for moving out of OSM to OHM.

What problem would be solved by this action? Making "the map" more correct? But "the map" *already* doesn't render abandoned railways, much less razed railways. It serves to make OpenRailwayMap less correct. That can't be a good thing. It makes the ITO subject-specific maps less correct. That can't be a good thing. I can understand if someone deletes a railway by hitting the wrong key. I can understand if someone deletes a railway that is tagged incorrectly as disused or abandoned when it should be tagged as dismantled. I can understand if somone goes to the location of an abandoned railway, and doesn't see the evidence that an expert sees. But surely the person who made those mistakes will not be unhappy if his mistake gets reverted and the tagging (if incorrect) gets fixed. -- --my blog is athttp://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog ___ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us

Depending on the climate, a corridor can become all but invisible on an air photo long before even the tracks are removed. There is no firm line between OSM's definition of physical characteristics on the ground. I've followed hundreds of miles of such corridors, and only those still "active" enough to be candidates for trail development, yet faced severe challenges staying on track as it were. These railbanked corridors are in a legal sense still active: they're still registered with the Surface Transportation Board, yet they can take a real eye and skill to actually find. Armchair deleting them because you can't find them on an air photo seems to go too far. ___ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
