Finally got around to reading this and it's a good post except it's odd in my opinion to compare plotting rasters with ggplot2 to plotting rasters with any other package but never mention tidyterra, feels like it's a gamechanger compared to geom_raster #RSpatial

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

- New file formats (e.g. #GeoParquet)
- Geospatial DBs (e.g. #DuckDB + spatial)
- Global discrete grids

What would you add?

A discrete global grid (DGG) is a mosaic that covers the entire Earth’s surface. Mathematically it is a space partitioning.

🚀 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.

How spatial sampling methods affect the variance of your mean estimate when spatial autocorrelation is present.
https://dosull.github.io/posts/2025-11-14-gia-chapter-2A-spatial-autocorrelation/
Shows four density charts. Each chart represents a sampling method: poisson, grid, evenly spaced, and clustered.. Each chart shows two densities: random (no spatial autocorrelation) and smoothed (spatial autocorrelation). Grid and evenly spaced show too narrow variance estimates while clustered shows too wide of a variance estimate.

tmap or ggplot2 for maps? 🗺️

All 8.1 million US Census blocks.

Visualized smoothly in 3D.

Instant population and housing totals from a lasso selection.

All running seamlessly in the browser, no traditional backend.

While everyone’s talking about AI, it’s an incredible time for geospatial tech.

Any #rspatial / #tmap folks know how to do linebreaks in legend titles in 'View' mode in {tmap} v4 and care to help a fella out? I'm probably missing something obvious but equivalent methods I used to use in v3 aren't working for me... (reprex in alt text)
library(tmap) library(htmltools) tmap_mode("view") # Single line legend, \n has no effect tm_shape(World) + tm_polygons( fill = "pop_est", fill.legend = tm_legend( title = "Long title for\npopulation estimate" ) ) # Single line legend title showing HTML tags tm_shape(World) + tm_polygons( fill = "pop_est", fill.legend = tm_legend( title = paste0( "Long title for", br("population estimate") ) ) )

#rstats #rspatial #tmap geek question: I need a log10 scale for my line widths, which I can get with `tm_scale_continuous_log10`. But in the legend, I'd like to have "1, 10, 100, 1000" rather than "10^0, 10^1, ..." I haven't been able to figure out how to do this.
A tmap map showing lines of different widths. The width represents "Potential student cyclists" according to the legend. The legend labels all have log10 notation.

Calling for Beta Pilot Workshops: Geospatial Data Carpentry for Urbanism
Researchers from the Department of Urbanism and members of the Digital Competence Centre at TU Delft have worked since 2023 on the curriculum Geospatial Data Carpentry for Urbanism, currently in The Carpentries Incubator. This curriculum, inspired by the pre-existing Geospatial Data Carpentry, part of The Carpentries, was designed to introduce learners from the domain of urbanism to the use of R programming when analysing and visualising vector and raster data. It also introduces basic GIS operations using R. These skills are particularly relevant when working in the field of urbanism, but can be applied to other urbanism-related ones.
