I was interviewed about a great new #opendata #gis layer on imperviousness in the Netherlands developed by #Friedenau Society for #KlimaatEffectAtlas. Read here: https://klimaatadaptatienederland.nl/actueel/actueel/nieuws/2025/groen-nederland-kaart/
Hoe groen is Nederland? Deze kaart brengt dit nauwkeurig in beeld
Nederland moet vergroenen, maar waar begin je als je niet precies weet hoeveel groen er al ligt? De vernieuwde Basiskaart Groen en Verharding in de Klimaateffectatlas brengt dat in beeld. Met deze kaart kun je tot 25 centimeter nauwkeurig zien hoe groen onze buurten werkelijk zijn.

#30DayMapChallenge Day 30 – Makeover
Traveling today to Marrakech 🇲🇦 for a water trade mission, so I kept it simple. I revisited my Day 2 map and turned the Schie, Coolsingel & Goudsesingel back into water bodies 💧.
Stronger blue infrastructure = better climate adaptation.
