⚽ Is synthetic turf taking over European football? 🇩🇪 leads on grass with 27.8k (78%) pitches, but 🇪🇸 & 🇹🇷 have flipped to 54% synthetic turf and 🇲🇹 sits at 91% artificial turf! PitchWatch maps these surface classes globally using #Copernicus #Sentinel2 satellite imagery. 👉️ map.pitchwatch.football
Every football pitch tells a story ⚽ Ash pitches get refurbished to grass 🌱 grass gets replaced by synthetic turf. These shifts happen continuously, but they are rarely tracked at scale. 👉️ pitchwatch.football monitors football pitches & classifies surface types, and is mapping changes over time.
Das ist sehr, sehr beeindruckend: @luisaneubauer.bsky.social über ihren Nazi-Urgroßvater, über seine Schwiegertochter, ihre Großmutter, und was das mit heute zu tun hat.
Interaktive Karten werden oft bei kommerziellen Anbietern außerhalb der EU eingekauft. Das bringt Abhängigkeit, Rechtsunsicherheit und kann mehrere 10'000 € im Monat kosten. Unser Gegenvorschlag: Lasst uns digitale Infrastruktur gemeinsam über ein Konsortium betreiben. 🧵 versatiles.org/consortium/de

I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

Always beautiful, the train journey from Prague 🇨🇿 to Dresden 🇩🇪 along the Elbe River / Saxon Switzerland.
🔌💡 Power outage from April 28 in the Iberian Peninsula is in parts still visible from space. This VIIRS nighttime imagery shows a clear drop in light emissions across southeast Spain (Almería, Murcia, Albacete) on April 29, 2025. lnkd.in/gghZ__Kh 🌍 Data: NASA Worldview / Suomi NPP VIIRS #PowerOutage
Just came back from the Fisherman's Trail (Rota Vicentina) in South-West Portugal. 10 days (240km) of ocean views • wind • waves • plenty of sun • but also rain. Loved it. 🇵🇹
