I had a lot of Fable tokens to use up before my weekly reset, so I made this live 3D map of London with Three.js Every train, bus, boat and plane is real and live right now! - Tube, bus and riverboat data from TfL - National Rail trains from Darwin live departure boards - ADS-B for planes and helicopters - AIS feed for boats and ships - Map data from Overture and OpenStreetMap Trains and buses have no GPS feed, so their positions are inferred from arrival countdowns and departure boards, then animated along the track/route geometry

Huge news. @wmata API now updates every 5 seconds! Adjust your apps, people!
👇 This is a big upgrade for Better Bus service. We have been working on this for a bit and the new tech is going to make tracking 🚌 more accurate & faster. This means better real time data so better OTP, Control Center can help reduce bunching/gapping & apps are more accurate.

I made a super simple website where you can see everywhere you can get to in under an hour on the NYC subway. The generated map is both a heat-map (changes color) and a cartogram (warps space). castrio.me/nyc

I'm scraping Amtrak, and made a website to see how busy each train is!

When I moved to new york, I found it hard to visualize what commute times actually looked like. The same dilemma occurs every time you move, or even book a hotel: what's actually accessible in 20 minutes of public transit? Deployment link below

Continuing our @Kpler analysis of GNSS spoofing in the Strait, this animation uses raw unfiltered AIS data to compare Feb 27 vs 28. The chaotic tracks on the 28th show intense GNSS spoofing with red lines showing AIS “jumps” caused by interference. #dataviz #ais #StraitofHormuz

Building ride playback with speed visualization in Mapbox GL JS? A developer on Reddit asked how to color-code speed along a bike route (green → yellow → red) and add interactive scrubbing to reveal speed time data at any point. We built a working demo. This post shows how to: ✅ Use line gradients to visualize speed variations ✅ Dynamically build gradient stops based on speed data ✅ Implement hover-based route “scrubbing” UX Includes a live CodePen you can fork and adapt.

Built an app for cyclists who record their rides. Telemetry Studio syncs your bike computer data to video and adds overlays - power zones, heart rate, speed, GPS map, elevation. Works with FIT and GPX files. Strava segments too. Download and try it free at telemetrystudio.com

Interesting: @DDOTDC has placed two speed-sensing cameras along the Metropolitan Bike Trail that show a smiley face if you’re riding under 15 mph or a frown if you’re above. City officials say it’s to encourage safer riding, but they are also collecting speed data from cyclists.
