#30DayMapChallenge starts tomorrow: 30 days, 30 map ideas. If you’re using R, Python, or Julia, consider sharing open-source examples or tutorials. 🧭 30daymapchallenge.com #GeoData #DataViz #Maps #SpatialViz

Looking for an overview of different #RStats packages for visualising spatial data? 📊 Here's a previous blog post of mine: nrennie.rbind.io/blog/r-packa... This blog post is almost three years old now, but all of the code still works! #DataViz #RSpatial #30DayMapChallenge

Join us today at 4pm! Kick-off meeting to prepare our upcoming #30DayMapChallenge with R

It's that time of the year again! 🗺️📍💻 #30DayMapChallenge #30DayMapChallenge2025 #30DayMapChallengeRbanism 30daymapchallenge.com

This November, Rbanism launches the second edition of #30DayMapChallenge and we invite researchers, MSc and BSc students, and map makers to join us! For 30 days, we’ll explore together creative mapping through daily themes, all scripted and coded in R! Scan the QR and join #Rbanism #R #bk #tudelft
