I'm thrilled to announce that I will soon be an author! My book, The Twin Cities in 50 Maps, is a cartographic portrait of Minneapolis and St. Paul. The book includes 50 painstakingly designed maps and deeply researched essays that trace the Cities' urbanity, history, ecology, and culture.

Going through the Knoxville Library archives, looking for photographs of a building or two, and I came across this guy. I can't get over how insane it is to fly a plane like this. No cockpit, windshield, or anything. Just flying a canoe in the air. lol

This chart scaling is... a choice. It's like reverse mercator for every ten latitudes or something.

How many twilights are there? What is a true night? Which places go without it, and for how long? Ceren from our support team answers these questions with some very cool maps! 🌃 🌐 🗺️ www.datawrapper.de/blog/twiligh...

TIL the midnight sun at the north pole lasts about a week longer than its polar night (186 vs 179 days, respectively). This is due to our slightly elliptical orbit around the sun. We are further away from the sun in July and closer in January. All of this info is counterintuitive to me lol.

Earlier this year I got to play around with some Roman roads data for @sciam.bsky.social. The article (with four of my #maps) is out now: www.scientificamerican.com/article/new-...

Searching my photos for “map” this morning—as one does on Sunday morning—and studying @aasmith.bsky.social’s Prudence Island map which was labeled as “map inspiration” in my photo. 🔎🗺️ antonioantoine.com/product/prud...

Not a good sign! Although I wish this study had been published when I was in grad school.

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

Appalachian Trail Forest Map (WIP). I finally created a hillshade in Blender. S/o to @pinakographos.bsky.social for the great tutorial. It took me a few tries (over several months). I am impatient when it comes to Blender. I am changing the format to an oversized map. Wish my computer luck. 🫡

I saw a post on LI about a small AI company co-founder complaining about professors not letting students use AI in the classroom. His point was that AI was using "common knowledge" so professors needed to adapt to the changing times. Which is clearly missing the point of doing the work.

Percent of Residents Living in Their Birth State, by County.

Oh man. The blue land broke my brain for a bit.

Posting this mostly for myself. How to print transparent backgrounds in QGIS. There's a second background to turn off. #gischat gis.stackexchange.com/questions/19...

You can see a copy of Antonio's work printed here at The Map Center!

Rhode Island Shipwrecks Map 🗺️ As someone who lives in or near the mountains, shipwrecks are like barn finds, except the barn is a dungeon, and the monsters are not too thrilled about you taking their treasure. More deets: antonioantoine.com/2026/04/19/r... #gischat #cartography

Welp! I don't know how long my site's visibility was set to "Coming Soon", but I guess that explains the traffic nose dive.

I built an interactive guide on how GPS works! perthirtysix.com/how-does-gps...

I can't tell if I am accidentally unliking a post or if my likes aren't registering on BSKY lately. If the post shows up in the algo again, the like is missing. Sometimes, when I click on the post, it shows up. If you experienced this odd behavior from me, I am sorry! lol

One day, I will remember that CT changed their counties to county equivalents before nearly wrapping up a map. 😭 #gischat

Next Joy Plot Map is Ohio. Lots of people, very flat. #gis #gischat #cartography

Colorado Pop x Elev Joy Plot We can see a pretty good relationship between elevation and population density in CO. Even though the Rockies and high plains cover some of the small cities and towns. I may add an offset or extra VE point for the population layer. #gis #gischat #cartography

Thanks, I hate it! Side note: I was born on the 10 year anniversary of the moon landing in the Rocket City. More reminders of mortality at profmusgrave.github.io/anotherday

Now that I have a working model in QGIS for my Joy Plot workflow, I can focus on refining the maps. I have been interested in mapping elevation and populations for a long time, but I have struggled to find a method that shows both variables evenly. Joy Plots look promising. #gischat #cartography

I think I just lost a year of my life trying to get a PyQGIS environment set up in Pycharm. On the plus side, I finally built a working model in QGIS for one of my workflows. I may try to turn it into a plugin one day.

I am finally wrapping up this Rhode Island Shipwreck map (at least enough to print out a draft), and I am low key digging this inset map more than the main map. 😅😂 #gis #cartography #maps

Ah, that fun moment when you realize the data you collected from official sources, then spent time cleaning, formatting, and plopping it onto a map, has to be guessetimated anyway. 😭🤦‍♂️

I haven't used this site in over 10 years and it has come in clutch twice this past week. #gischat www.earthpoint.us

Rivers across Alaska and the wider Arctic are turning bright orange, as increased temperatures cause iron and other metals to leach into waterways, as permafrost thaws and glaciers melt Read @fteva.bsky.social and my visual story here as.ft.com/r/824504f0-d...

Median Generations by County (2023) Another version of my previous map. I used the #QGIS 2.5D symbology with a standard choropleth. It is a little confusing to use, but I think I get the gist of it now. The counties are extruded by population. #gischat #gis #cartography #maps

This is pretty cool. I am near the middle of the Geospatial Professionals.

I love a custom north arrow.

Our paper “Inferring fine-grained migration patterns across the United States” is now out in @natcomms.nature.com! We released a new, highly granular migration dataset. 1/9

The Utah Historical Society just produced a new, excellent map of "The Peoples of North America in 1776." Great resource for anyone teaching, writing, presenting about Native peoples as part of their 250th work. america250.utah.gov/power-of-pla...

Five classes I took in college. - Intro to Art (I still think about this class) - United States History in the 1970s - Climatology - German Fairly Tales - Microeconomics (yuck) Honorable mention for statistics. Also, taking an econ class dropped my opinion of econ into the toilet. Lol

I made a Median Generations map of the US for a contest, but I missed the deadline. 😅 The generations are based on the median age of census tracts in 2023. The urban areas are tract centroids, and the rural areas were dasymetrically binned to a 10km grid. #gis #cartography #gischat

Just an incredible and unusual landslide at Niscemi, Sicily, Italy, as captured by @planet.com SuperDove satellites 🧪⚒️🛰️

Animation showing the plunge of cold Arctic air which is causing disruption to flights and has left almost a million people without power Read Martha Muir and Ilya Gridneff's report www.ft.com/content/8757...

For context, before 1980, #Nashville temperatures hit 0°F an average of once per winter. Because of #GlobalWarming, what used to be an annual event has only happened 4 times in the last 30 years. Similarly, before 1980 we got 12" of snow in an average winter. Since 2000, it's around 4".

Increasing hazard situational awareness is always worthwhile, and disaster maps are never excessive. I made this US #WinterStorm map with a dark background (save battery during outages), a vertical layout (mobile viewing/sharing), colorblind friendliness, and county/city references. Source: #NOAA

Do you appreciate @nws.noaa.gov's posts on Bluesky? Did you know that this account is a pilot program that may or may not be continued and even expanded to NWS field offices? NWS is soliciting comments here! www.surveymonkey.com/r/PrototypeN... Press release: www.weather.gov/media/notifi...

I created a quick workflow on how to find the highest value from multiple attribute columns in #QGIS. This is helpful if you have temporal or similar data in a single feature class. In my example, I had over 100 columns to compare. #gis #gischat

Interesting #QGIS plugin for quick feature show/hiding. www.reddit.com/r/QGIS/comme...

The first JHU GIS After Dark in 2026 is on February 5th from 7-8pm featuring Lauren Teirney from ESRI. The event is free and open to the public, however, you need register to attend. #gis #gischat www.eventbrite.com/e/gis-after-...

This simple label took me over day to make. I am still learning expression builder in #QGIS. I needed the highest value for each feature from over one hundred attribute columns AND the name of the field name. The worst part is I don't know if I will use this info. lol
