R, Rust, Geospatial "AI", and laughs with @fransvandunne.com and Diego of @ixpantia.com on their Podcast @datalatam.bsky.social

It was a blast! Thanks for having me.

🚀 Excited to speak at the Rome R User Group Thu, Nov 27 (6PM CET)!

I’ll show practical workflows for geospatial predictive mapping in R — including tools to avoid spatial bias and improve prediction reliability.

Chapter 7 of Geocomputation with Python shows how to:

🔹 Find spatial datasets (geoportals & download tools)
🔹 Work with different file formats (strengths & limits)
🔹 Read & write vector + raster files efficiently

tmap or ggplot2 for maps? 🗺️

David O’Sullivan breaks down the trade-offs in a blog post.

tmap vs. ggplot2 for mapping – Geospatial Stuff
For me at least the choice between ggplot2 and tmap is an ongoing question. Here are my latest thoughts on the subject (with code).

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

Chapter 6 of geocompy dives into:

- Geographic vs projected CRSs (lon/lat vs meters)
- Getting, setting & reprojecting CRSs
- Why ignoring CRSs can break your analysis 🚨

The {sf} package continues to blow my mind with how easy it is to make maps with #rstats and ggplot (code for that map here gist.github.com/andrewheiss/...)

Thank you @hormiga.bsky.social for writing this book. Beyond learning what may be right/wrong with current practices and many new tips, it makes you think throughout what kind of teacher you want to be and how to get there. Highly recommend

I've been posting about PMTiles for geospatial visualization for good reason.

However - you can push mapgl quite a ways without tiles!

In this post, I cover how to map all 85,000+ Census tracts in the US without pre-tiling, along with performance tips.

A lot of you are asking about PMTiles - one of the most exciting innovations in geospatial in the past decade.

My most recent blog post helps you get started. Use this reproducible workflow to learn how to create, explore, and visualize PMTiles.

Still fascinated with #webR and its potential for teaching stats

Here students can play (even from their phones) and find out themselves how the p-value depends on sample size
