#30DayMapChallenge (10 minute map)

This is trees tended by the city of Zürich, sized by tree crown diameter.
Done in Python, with loading data into duckdb and graphing on lonboard. The map is actually clickable and gives you meta-info about the trees when clicking on a tree.
I wanted to actually intersect this with street names containing tree names, but 10 minutes were not enough for that :).

Crazy how quick you can get to something with open government data (OGD) and these modern #geocompx tools I am just discovering...

OGD data found via:
https://opendata.swiss/de/dataset/baumkataster/resource/d0ecd9ca-45fb-499b-9171-aac76b00fb42

My contribution to today's #30DayMapChallenge (Minimal Map)

This is a map of two months of cycling to work, two days a week, between Zürich and Winterthur (and exploring my options for gravel and beauty).

Done with duckdb + lonboard in Python. Repo here: https://codeberg.org/marioangst/winti-zh-gpx

I am quite new to doing spatial data, coming very much from the non-spatial data science side, but I'm having fun and I've got to say the #geocompx resources out there are really cool nowadays.

Confused about coordinate reference systems (CRSs)? 🧭🌍🐍

Chapter 6 of Geocomputation with Python dives into:
