I recently have been on vacation on Helgoland and did some mapping there. I noticed that one area which was used for camping has been recultivated, so the mapped paths and features in this area are no longer there.
(as I’m new in this forum I adjusted some of my links to have all information in one post and get around the “max 3 links in one post” restriction)
During my vacation I added following Notes to the map:
from this side, the way is no longer visible
second entrance - probably the best visible part of the former path
third access path - not really visible anymore
I did not follow the paths, but I suppose that e.g. the camping places inside /way/273806295 are no longer in use.
If I remember correctly, the information board /node/2674960159 also states something about the recultivation process, I found a short post about that recultivation here: www.duene1.de ♥
Now my question: how should I adjust the map?
a) Should I just remove the paths and traces that should no longer exist? (e.g. remove the benches like /node/2675043078 and trash cans?
b) Should I add a tag like Key:demolished:* or wiki/Key:removed:* to the (visible) pathes?
c) perhaps the sign posts depicted in my photos could be added as barrier or information board?
I’m not sure about the area /way/247250782 - it is still visible as a separate area but I suppose it is no longer used for camping.
I’m glad to hear your advices on how to adjust this area.
not far away I also removed a path of the beach access as it is no longer available - I suppose this may have been changed around the same time, perhaps some local editors know? (see /changeset/139408394 and /note/3802534 )
Hello Christoph and welcome on the forum.
So, I would recommend the following:
- If a path is completely gone, then you remove it.
- If a path is visible but is in the process of fading away, you use the appropriate lifecycle prefix see: Lifecycle prefix - OpenStreetMap Wiki This is to prevent another mapper from adding the path again.
- If the path is still there but it is illegal to use it, add access=no/private etc.
This same process can be applied to the benches, trashcans etc.
Is this enough information so you can continue?
Thanks for your answer, @Tjuro.
at least one path seems to be gone - the other one is not really visible and marked with a sign “no access” - but I didn’t check how far into that area the path is still visible (if that counts as visible - see the photos on my notes).
Or perhaps I could leave the outermost part of the path?
Regarding the lifecycle prefixes: I wondered whether disused or demolished would be appropriate - I suppose these pathes have been much more visible before removal / recultivation.
For the benches and trashcans: I assume that they have been removed but as nobody should access I could not check it. Is it safe to assume they’re gone?
If the paths or other features are still visible on the aerial imagery for the area then I would use the lifecycle prefix tagging to indicate they have been demolished. Even if they are not visible on the ground if they still show in aerial imagery there is a chance that if you delete the ways in OSM someone might add them back. By leaving the ways there but using the lifecycle prefix tagging you will be warning a future mapper that their imagery does not match what is on the ground.
In this case, I think that is fine. But it is recommended to check in some way that they are gone. like on arial imagery. or try to view the benches from a path/hill that you are allowed to access.
ich würde auf jeden Fall die Hinweise von n76 berücksichtigen, da auf den zum Mappen zur Verfügung stehenden Luftbildern die Wege teilweise noch sichtbar sind und nach dem Löschen die Gefahr groß ist, dass jemand die Wege wieder nach Luftbild einzeichnet.
Insoweit sich Flächen geändert haben, sollten diese nicht gelöscht und neu gezeichnet werden, sondern sowohl in Geometrie und Tagging geändert werden.
Was die Mülleimer und Bänke betrifft: frag doch einfach den Campingplatzwart, direkt vor Ort (wenn Du noch dort bist) oder telefonisch.
thanks for all the hints. I will try to contact locals to find out what is still in that area… I should have asked here in forum while I was on vacation, but I did not have proper network access there - only my phone.
I will check arial images and probably mark paths as demolished and remove trashcan and benches based on what I can find out via phone
I did not receive any response to my mails, so I called them via phone instead. I got confirmation that the area was cleared and is not used anymore. looks like Alpin100 already edited that area, so there is nothing more to clean up for now.
