We built an API to retrieve the trees in Berlin but we have never build something useful with it. Maybe you have an idea what to do with them? https://codefor.de/projekte/2016-07-18-be-street-trees-api.html

I will brainstorm a bit on this and see if I can implement the ideas myself but feel free to jump on any point:

So for each tree we have potentially the information for the column names listed here.

Looking at the map, info for the following columns seems to be available and interesting:

  • baumhöhe (tree height)
  • stammumfang (trunk circumference)
  • kronendurchmesser (crown diameter)
  • art (genus)
  • pflanzjahr (year of planting)
  • alter (age)
  • eigentümer (owner)
  • bezirks ID (district)

I think the following statistics/relationships would be interesting to look at:

  1. Single-column statistics overall and per district:
    How does the distribution of e.g. tree height, year of planting or tree genus look overall and per district? Are there differences between the districts? What types of owners are there? (I thinks it's mostly publicly owned but not sure)
  2. Column relationships:
    I guess the tree height/trunk circumference/crown diameter should linearly depend on the tree age but is it the same for different districts/owners/year of planting? How does it look within a single tree genus?
  3. Spatial dependencies
    Of course for all of the above, the indicators can be analyzed in a spatial manner as well.

A good first step would be to update the date at https://trees.codefor.de/.
It says <downloaded_at> 2016-08-13T23:02:56Z … <ingested_at> 2016-08-15T21:02:31.614Z on the trees.


I see some interest in the data attribute "age". For example this article https://www.neukoellner.net/alltag/vom-altern-der-baeume-in-der-stadt/. There are also quite a lot results for google searches like "neukölln ältester baum", so it has some traction in the press.


I am very interested in the accuracy and "up to dateness" of the data. A comparison with OpenStreetMap OSM data might be a good place to start. I am, however, not sure how to go about it, since no datasource is more "right". Some OSM data have a timestamp, so that might be a good indicator. Some mapper change a natural=tree to natural=tree_stump if the tree gets cut down (Example: https://www.openstreetmap.org/node/5514235575). Those might be interesting to compare.


There are some areas - like "Hasenheide" - where a lot of different types of tree are planted. That might be interesting to analyse.


Finding a way to add the data - or enrich the data - in OSM would be a great step. I tried using it with mapmeld/iD#66 but failed due to incompatibility with the geo-json-services.

I ran a workshop at Bits und Bäume a couple of weeks ago where we tried to come up with use cases for all the tree data. People wrote down their ideas on cards that I now digitised. Feel free to take a look at those for inspiration. If anyone would be so kind to maybe extract the handwritten text from there to a plain text list in this issue it would be much appreciated.
