So far my only (tiny) suggestion is to make the pop-ups for the "Go to my current location" tool either close themselves after some time or be closeable by the user. I opted to not change the location access setting in my browser, but the pop-up persists, and I don't see a way to close it.

I've been studying contour/elevation/relief maps for upwards of 30 years and this one stands out for its wealth of visualization options and elegant interface. Pretty amazing to explore. High resolution in NL is extra cool. Even keyboard shortcuts!

This (to be clear, the linked article) was the first time I'd heard of snailjet. Great concept, and great name! I'm curious how the stickers will look in 20 years. Maybe you'll report back then?

Part 2, mostly for the nerds: Zuzai is a recursive acronym. It stands for "zuzai uses zero artificial intelligence" If you like the idea, please spread the word! 2/2

I wrote something, based on my conviction that the current moment calls for a new word. A nice, crisp word to indicate that something was made or done *without* AI. My proposal for this new word is ... zuzai. zuzai.org 1/2

Here are the original displayed image (in the one above I added the yellow for better visibility) plus one with time zones, which is more cluttered but provides additional context. Also, if you're really super curious, here's the FlightAware depiction, too: www.flightaware.com/live/flight/... 3/3

The flight path was not a great circle. Evidently so many airlines are avoiding Russian and Iranian airspaces that there's something of a bottleneck on the route between the two airspaces over Azerbaijan. (When I flew from Amsterdam to Tokyo, that's the route that KLM chose.) 2/3

Surprise on a KLM flight yesterday from Tokyo (Narita) to Amsterdam: the entire flight was in an eastward direction. Though both Tokyo and Amsterdam are in the Eastern Hemisphere (with ~⅜ of the world's longitude between them), most of the flight was in the Western Hemisphere. See image & 🧵. 1/3

I have no immediate plans to migrate the content to another platform; the explanation is based on a set of numbers and groupings that are now outdated. At some point I would like to provide an updated version. If folks have recommendations for FOSS scrollytelling platforms, please let me know! 3/3

Blake Esselstyn @mapblake.bsky.social · 23/02/2026
One thing about this early generation of scrollable story maps is that the content can't be indexed by search engines. Nonetheless, as of today, the explainer has had nearly 3,000 views, almost all presumably driven by people sharing links to it. Not too bad for a somewhat arcane topic. 2/3

In 2019 I created a Story Map explainer of NC's distinctive county grouping requirement for legislative redistricting. Soon that resource will vanish (Esri is retiring that old platform). If you want a refresher on the so-called "Stephenson" process, now's the time! #NCPol 1/3 arcg.is/1DnDO

Fascinating exploration. In 2024, I was a visiting instructor introducing GIS, and a student from Western Sahara refused to accept that Felt could be a credible tool given how its base map showed Western Sahara's boundary (unlike UN, Wikipedia, Google, NatGeo, etc. when viewed from the Netherlands).

- I did not make a significant wrong turn that required rejiggering the route, nor was there congestion on the roads that would have been nice to avoid. - The car I was driving didn't support Android Auto. - Yes, my phone is set to French language, in anticipation of #QGISFR2026 🤓 3/3.

Other notes: - I was driving from Maastricht to near Charleroi in Belgium. YMMV depending on OSM data. - In the screenshot, you can see I was in flight/airplane mode, using downloaded data. Still worked well. - It also offers the "first person driver" view. I just prefer keeping north as up. 2/3

After years of using Google Maps as my primary app for driving navigation, today I drove to an unfamiliar place using @organicmaps.bsky.social for the first time and was pleasantly surprised. Particularly nice was that the app was less talkative, not stating the obvious (e.g., merge). 1/3

Do you know anyone whose birthday is today (Sept. 16th)? If they like math—or even if they don't—you could point out to them that 9 / 16 / 25 is a sequence of perfect squares. AND! 2025 is also a perfect square (45²). Best time of day to acknowledge? Perhaps 1:04. 🤓

It also appears that this is not new news; the first such release evidently was in 2024. (For my work, I still mostly use the 2020 geographies because of their alignment with the PL 94-171 redistricting file.) www.census.gov/newsroom/pre... 3/5
