Cartographer with @Esri I make maps, and sometimes videos, and occasionally pasta. All typos my own. https://t.co/Nzg67KsSxa

Part 2 of my tutorial series on plotting spatial data in #Blender3D using #geometrynodes. This time we're plotting points on a 3D globe.

@themadstone The fact that whales exist is my constant reminder of magic in the world 🐋 Like there are shockingly intelligent creatures the size of boats drifting through the oceans and singing to each other all the time. How magical is that!?.

@collin_doucet @GusRachels @hankgreen That's the part I feel worst about. The cast is giving 110%, the people doing the stunts, effects and production design are doing the best work of their lives. The music and directing is better than anything else on tv. But all of their insane work is being wasted on bad scripts.

Taking another pass at visualizing this summer's wildfires. This time with GEOS-FP black carbon mass composited over the MODIS hotspot data. Tried rendering out a couple of months' worth while I wait for the rest to download.

@solarrsystem We don't know the real word for bear. The word "bear" literally means "the brown one". It was used in ancient times because people believed that using the bear's true name would summon it. The taboo was so effective that the original name was lost and we were left with "bear".

@ziroth @hankgreen Significant growth in wind but primarily natural gas. Not perfect but around half the CO2 per kWh compared to coal so certainly a massive improvement.

I love how hypnotic this animation of atmospheric humidity turned out! This was also a fun chance to try a new visualization trick: While humidity drives the color ramp, the brightness is modulated based on windspeed, which seems to give the whole thing more structure.

More experiments in data visualization in #Blender3d! Plotting 100k stars within 1000 light-years of the Sun. Thanks to @CgFigures tutorials for showing how to bring data into Blender. I love seeing the faint shape of the Milky Way emerge in the brighter more distant stars!

One of my favorite things about cartography is that every project gives me the opportunity to learn something new. For day 8 of #30DayMapChallenge - Africa, I decided to focus on a place that I knew very little about and explore a bit.

@PeterTiso @rachsyme I get that way about places. Like the city I used to live in kind of exists in two ways for me now. There’s the real, changing place that I don’t think about, and the place in my mind that’s frozen in the state it was in when I left.

@triops99 @philipjcowley My idea is that they should have qualifications as usual, and then reassign all the sports at random at the opening ceremonies. You placed first in qualifications for weightlifting? Now you're a rhythmic gymnast.

@Alsadius @contrapolitical @wonderofscience The reason they don't take more frequent images is because the things they're measuring (global weather patterns) aren't (usually) subject to extremely rapid change. So they spend their data budget on resolution rather than frequency.

@JessicaElisa93 @xkcd And it's weird that it gets reasonably close with the spelling too. You'd think that if it doesn't understand text at all it would spit out total gibberish, but it seems to get like 90% of the way there before it loses the plot.

@Alsadius @contrapolitical @wonderofscience B and C aren't true in this case. The satellites that took these images are new (2014 and 2018 respectively) and are in geostationary orbits (they stay above the same point on Earth).
