#30DayMapChallenge Day 13: Interactions
Every drop the Rhine and Meuse bring into the Netherlands fell on someone else's land first: 180,294 km² of upstream catchment, over 4× the size of NL.
Rhine at Lobith: 64% Germany, 18% Switzerland, 15% France
Meuse at Eijsden: 56% Belgium, 43% France
Made in #QGIS with #HydroSHEDS, finished with Claude.

#30DayMapChallenge Day 12: Power
The Grid Is Full ⚡

70% of TenneT’s 271 substations have no room for new consumers, 73% none for new feed-in. Randstad is full for taking power, the north and east for feeding in. 8.6 GW + 6.0 GW waiting at TenneT; some regions until 2036.

Made in #QGIS from the Netbeheer Nederland capacity map export (https://capaciteitskaart.netbeheernederland.nl/) + #OpenStreetMap substations.

Vom Fernwärmepotenzial zur konkreten Ausbauplanung: Wie geht das?

Wie wird aus der Analyse ein konkretes Projekt?

Darauf antwortet Welf Schröder (Bonn-Netz) auf der #Where2B 2026.

Im Fokus: erste Ergebnisse mit #QGIS und eine spartenübergreifende Ausbauplanung, die auch der Kundschaft mehr Transparenz bietet.

#30DayMapChallenge Day 11: Sound
The Sound of Rotterdam 🔊
Five open noise maps combined: which source is loudest in every 10 m cell?

🟠 Road dominates 78% of the area above 55 dB
🔵 Port & industry 14%
🟣 Rail 6%
🟡 Airport 2%
🟢 Wind <1%

Total noise as an energy sum (60 + 60 dB = 63 dB). Made in #QGIS with #RIVM and EU noise map data. Finishing touches with Claude.
