Is it possible to teach an Introduction to Data Science course in 3 hours? I will find out soon!
You can too if you attend the course this Friday as part of the MSc at the Institute for Transport Studies (ITS) in Leeds. You can also attend remotely, watch this space for #openaccess materials 🚀

I‘m super happy with working in @marimo.io. The reactivity + UI components make spatial work fun as well and can be combined with most of your bullet points. bsky.app/profile/fubi...
For real, @marimo.io feels like Svelte but for Python. Surreal DX (even on mobile).

tmap.mapgl wraps mapgl, allowing you to make performant interactive maps with the same tmap syntax you know and love!

I would add WebGL-based visualization libraries (e.g. #deckgl and #mapgl). They are not exactly super new but they're really centraly in how spatial data science has changed over the past 10-ish years.
ps. #GeoParquet, and #DuckDB + spatial ! would also be at the top of my list!

What are the most exciting trends you’re seeing in spatial data science lately?
