@tylermw.com's skymodelr package is so rad. So incredible what we can do with just a bit of #rstats code in 2026. Made myself a lovely new macOS Dynamic Wallpaper with skymodelr and the (also great) equinoxmac.com app.

Land cover of Guatemala. #rayshader adventures, an #rstats tale

Rivers of Australia. #rayshader adventures, an #rstats tale

Land cover of Romania. #rayshader adventures, an #rstats tale

Trying something different with a land cover map of Vietnam. What do you think? #rayshader adventures, an #rstats tale

Thanks to feedback, here's rivers and subbasins of the Great Lakes, take two. I'd mistakenly excluded Canadian lakes in my earlier render. Also took the opportunity to add more rivers. #rayshader adventures, an #rstats tale

if anyone in R or Python ever thought "gee I'd like to contribute to GDAL", I'm here to help you get started can guide you through good approaches, what to think about, and what's bare minimum for a bug fix or feature PR, and the python and C++ tooling you will need (speaking linux)

The Tufte LaTeX class is pretty, but it hasn't been updated for years and doesn't work with well with Quarto/lualatex. But with #QuartoPub you can replicate it on your own in HTML/PDF with just a little bit of customization with CSS and some preamble-y things! github.com/andrewheiss/...

Rivers and lakes of Wisconsin. I see the broken linestrings...turns out it takes more effort than I anticipated to resolve. I can fix the entire river, but it breaks when I intersect. Would appreciate any suggestions. #rayshader adventures, an #rstats tale

Land cover of India. This was edifying. I had no idea so much land was devoted to crops. I mean, I sorta knew but seeing it this way really hammered it home. This was also the render that drove me to pure GDAL for raster operations. #rayshader adventures, an #rstats tale

Land cover of Egypt. #rayshader adventures, an #rstats tale

gdal is at least an order of magnitude faster than R. I will remember that from now on.

Rivers of Iberia. #rayshader adventures, an #rstats tale

Land cover of South Korea. #rayshader adventures, an #rstats tale

These broken linestrings after I intersect are testing the limits of my patience and ability.

Freshwater major habitat types of Thailand. #rayshader adventures, an #rstats tale

And other one with rivers of Germany. #rayshader adventures, an #rstats tale

Back to the United States with rivers of New Jersey. #rayshader adventures, an #rstats tale

Land cover of Sri Lanka. The last time I did anything related to land cover was *checks history* almost three years ago. And I remember why: I spend way too much time on colours, just to end back up with the original palette. #rayshader adventures, an #rstats tale

Heading outside the United States with rivers of India. #rayshader adventures, an #rstats tale

Rivers of Rhode Island. No labels but should there be? #rayshader adventures, an #rstats tale

Rivers of Texas two ways, one with labels, one without. #rayshader adventures, an #rstats tale

The topography of race and income in New York City. #rayshader adventures, an #rstats tale

why would I get AI to write my documentation and examples, that's the best part. #RStats #rayshader

The topography of income: New Jersey. #rayshader adventures, an #rstats tale

The topography of race in New Jersey. #rayshader adventures, an #rstats tale

The topography of race in the great state of California. I've yet to solve the problem of overlapping points, which is why the map with all groups look different. I've access to height (since it's 3D) but it doesn't quite work here. Hmm. #rayshader adventures, an #rstats tale

The topography of race and income in Manhattan, NY. Rather revealing in a number of ways, no? #rayshader adventures, an #rstats tale

Been questioning the point of sharing stuff lately. It feeds the machine and people use the machine to copy and profit. But I remembered why I started sharing initially so here's the topography of race in the conterminous United States. #rayshader adventures, an #rstats tale

Does anyone happen to know whether XQuartz issues are fixed in macOS Tahoe? Asking for #rayshader in #rstats :P

I would have preferred to have the "draw the rest of the owl" meme on the cover, but this will do. Seems like it is on schedule, and we'll leave some typos so you know we didn't write it with AI.

New tutorial post on the blog: "Urban Relativity," discussing my method for comparing city populations with their surroundings, which I sometimes use to help decide which cities to show on a map, and which to leave off. somethingaboutmaps.wordpress.com/2026/03/23/u...

Reading @tylermw.com's new post on the latest rayverse update. Best lines so far: "...a cartel of cartographers formed an illumination illuminati to plot an influence campaign so you would understand their plots." "...in effect, all terrain maps are pretending to be Norwegian." 😂
