Hi,
User ‘GhentTheftAuto’ has started importing trees from the Ghent Open Data into OpenStreetMap.
This was not done without any oversight. I’ve sent a CS-comment to them, and they indicated that they were willing to give some more explanation. I’m kindly inviting them to this thread.
hello!
I built a front-end tool that I run locally to manually compare the coordinates of existing nodes that were tagged as tree.
If an existing tree node is close to a tree described in the Open Data dataset, I add the genus and optionally a circumference for the bark. If there was no tree present in OSM, I create a tree with the properties from the dataset.
Later, I plan to use LIDAR scans to give the trees height information as well.
If there are any changes needed or more questions, I’m happy to answer them, I think it’s a very nice feature to have tree species and optional circumferences/heights for the trees in Ghent on Open Street Map 
Cheers
lucas
Great!
Which attributes do you import with your tool?
How do you handle possible duplicates and data conflation?
Would you be willing to share the webtool and the source code?
Unfortunately it seems like someone has already removed many of the references at Changeset: 167942176 | OpenStreetMap , though I see you restored some of them. (E.g. Node History: 2131311318 | OpenStreetMap is still missing.)
Uh, and they mention duplicates & triplicates. Have you looked into that yet?
I import relevant attributes such as genus and circumference provided by the dataset alongside the unique identifier they provide, this is not truely needed if the relation is resolved purely spatially but I think the fysgro_id has merit as a way to backtracing to this dataset, which does get updates, some rather recent trees from 2025 are included e.g.
I think the above concerns duplication and conflation but I’m open to more suggestions!
Ofcourse I would, I have no viable way (and maybe need) of hosting it for now but I can share the source code with you if you have a Github account you can DM me?
Yes I contacted meuschel after his changeset and I made new edits based on his feedback.
EDIT: I can only make 3 replies so @joost_schouppe: yes I picked this up with mueschel, I was a bit too eager in the beginning 
Please share the source code with me. pietervdvn (Pieter Vander Vennet) · GitHub
You are also welcome to host the source code on https://source.mapcomplete.org
Or we can talk about all this in Nerdlab
Hi, nice project. Thanks for your effort.
I see you add for example “species=Tilia europaea ‘Euchlora’ (x)”.
Wouldn’t “species=Tilia europaea” and “taxon:cultivar=Euchlora” be better?
