Another great dive into the history of #dataviz 📊

We at Esri look forward to seeing you at #AGU25, showcasing with our products & services not only how geospatial enables greater understanding of the world, but how we also perform good science as a member of the scientific community. www.esri.com/arcgis-blog/... 🧪 🦑 🌊 🌎 🌍 🌏 ⚒️ #geogsky #geogchat

TIL (via @mapsbyw.com ): @jscarto.bsky.social made a global basemap with NASA data: visibleearth.nasa.gov/images/14719...

I just had to resolve a minor issue with the IRS, and the agent I worked with was fantastic, even during the shutdown!

Thoughts from Aravind Ravichandran as NASA (again) flirts with moving Earth observation to commercial data buys: “Here is an underappreciated irony: commercial EO companies already depend on NASA's public infrastructure.” newsletter.terrawatchspace.com/why-science-...

Volunteers Needed! Will you be at #AGU25? Consider leading a small group tour of the exhibit hall, focused on a theme or topic of your choice. These are science-focused discussions (no marketing!), with each tour ~30-60 min. Learn more & sign up by tomorrow: docs.google.com/forms/d/e/1F...

Divide and concur — this radical plan from 1920, for "lasting peace" after WW1, proposed uniting central Europe into 24 wedge-shaped cantons which would radiate out from Vienna’s St. Stephen’s Cathedral: https://publicdomainreview.org/collection/unionization-of-central-europe/

It took me about three months to get here but... Here's a 🪶 for (nearly) every species of bird, with colors extracted from wikipedia descriptions. 10,151 species. #dataviz #birds #data

Every time a bar chart is replaced by a dot plot an angel gets their wings. #datavis

These are now being generated from eBird checklists. I need to sort out a bunch of things but they're fun for testing. Colors of birds extracted from Wikipedia descriptions. 🪶

#30DayMapChallenge 🗺️ Day 2️⃣: Lines This map shows all the airports with direct flights from #Singapore’s 🇸🇬 #ChangiAirport (#SIN) rendered on a custom logarithmic azimuthal map. Airports that are served by more airlines, like Jakarta (CGK) and Narita (NRT), are shown more prominently. 🧵 1/3 #avgeek

It's the second day of the #30DayMapChallenge! Some friends of mine got a new place in Prospect Lefferts Gardens. Coming from Park Slope, the walk between each avenue seemed so much longer. It is. I mapped block lengths to see how it shakes out throughout the city: jillhubley.com/project/bloc...

I’m calling it. This is not a decent or good book & I recommend *not* reading it. slapdash, mediocre style, persistent errors & misunderstandings, & too narrowly focused. It is #NukePorn & bad even by those metrics. Read @armscontrolwonk.bsky.social’s The 2020 Commission instead. #NukeSky

A look at the devastating power loss across Jamaica following the historic crossing of Hurricane Melissa, captured by NOAA-21.

It *is* possible to make a weather map with good cartography! Perceptual palette, well-chosen projection, anti-aliased labels, and country borders with enough width to differentiate but not be distracting. 👏📊🗺️

If you take the time to read the whole Gates memo (which I did), the bulk of the content was mostly solid and encouraging. Really! It was the FRAME that was off--very off, from the first line. And when your framing is off, then how you make decisions and set priorities is off. THAT'S the problem.

Another tidbit in our new #Melissa story: the government shutdown means that federal researchers weren't gathering the usual science data during hurricane-hunter flights, because only mission-critical data were allowed. And those who did fly aren't getting paid. 🧪 www.nature.com/articles/d41...

Tell me you don’t know much about orbital mechanics without telling me you don’t know much about orbital mechanics: “Under Golden Dome, interceptors would be stationed in low Earth orbit and quickly swarm to the target during the short boost phase, kamikaze style.” wapo.st/47t77IV

Hurricane #Melissa update: imagery from dawn until about 2:00 pm local time, when the eye was squarely over Jamaica. At landfall sustained winds were about 185 mph, making Melissa one of the strongest hurricanes ever.

This new annotated JWST Picture of the Month features a cosmic creepy-crawly called NGC 6537 - the Red Spider Nebula. Using its Near-InfraRed Camera (NIRCam), Webb has revealed never-before-seen details in this picturesque planetary nebula with a rich backdrop of thousands of stars. 🧪🔭

Thanks to some vigilant friends out there, I have a nearly-complete 87-hour radar loop of #Melissa 's approach to #Jamaica. The loop abruptly ends when the radar is lost (either loss of communication with it or loss of the actual structure). bmcnoldy.earth.miami.edu/tropics/radar/

Always a good reminder, especially on days when colorful weather graphics are dominating the news.

While I’m awed by the other map-makers I’m listed beside, isn’t “contemporary cartographers” a better description than “living cartographers”? Aside from the unwanted reminder of mortality, it implies the field is overshadowed by the past.

Stunning video of the enormous eye at the center of hurricane Melissa. Taken by the 53rd Weather Reconnaissance Squadron “Hurricane Hunters” just before they had to abandon their mission. Melissa is extremely dangerous, the strongest Atlantic hurricane to occur this late in the season.
