Working on some micro mapping from a Mappillary capture I did recently and saw this “Please Clean Up After Your Dog” sign on the tree.
Mapillary Link for more context
I kinda know how to map signs individually but was wondering if there were specific tags that would let me map the sign and the tree on the same node?
Many thanks in advance for any help!
A few comments recently about similar things have suggested 2 nodes in close proximity, even with a location= for the sign as “tree trunk”
TY! Would be cool to have a system for tagging signs affixed to objects. Near me is a street light with 5 or so different signs on it and I’d rather not map 5 nodes clustered around it making it a nightmare for anyone else to edit.
Similarly, there’s over 4,300 occurrences of support=tree, most of them guideposts and trailblazes, but six are traffic signs.
Slightly offtopic, but piggybacking on this thread:
I’ve been mapping memorial=plaques that refer to individual trees (e.g. here and here) or to a row of trees here. The plaque is not on the tree, but refers to the tree. What would be a good way to indicate which specific tree the plaque refers to? A two-member relation?
I’d be wary of using relations to indicate referents, because some things can be referred to by so many other things, but this isn’t necessarily geographic information.
A plaque often refers to something in front of it, whether a tree, building, or former building (in which case the supposed relation would need to live in OpenHistoricalMap instead). subject=* and subject:wikidata=* can indicate this relationship without the complexity of a relation, but it becomes less machine-readable if the referent lacks a name or enough notability for Wikidata.
In the case of a plaque dedicating a tree in memory of a person, there’s also the question of whether subject=* indicates the tree or the person. This proposal would use memorial:subject=* to distinguish the person from the tree, though perhaps commemorates=* commemorates:wikidata=* would be clearer.
Support= !
Yes, that’s the term I was trying to remember, but could only think of location! 
Maybe also add a name (note / description) to the tree itself to match the plaque e.g. This Person’s Memorial Tree?
Sorry again to @CanopyFalls for this digression…
Thank you for the links and for pointing out that using a relation would a bad idea here. I thought that the plaque refers to (or commemorates) the tree and the tree then commemorates (or refers to) the person, but I can see that the chain of referents isn’t necessarily that clear cut.
I did think of adding the name on the plaque to the tree as well, but then there are lots of trees that themselves are named, so that would somewhat muddy the waters. Good idea about adding a description= tag to the tree-node! Thanks!
No worries, it was a digression I was interested in myself anyways. Thank you for adding to the conversation!
I’ve moved this into “tagging help and support” because it’s (a) fairly recently active and (b) essentially a question about tagging.
