From Hexagons to Foresight
How H3 hexagons, a spatial datacube, and visualisations turn Dutch geo-data into insight, time travel, and foresight. A deep-dive into the tools and methods behind Maps That Matter.
Interactive geospatial tools for the Netherlands — built with H3 hexagons, Deck.gl, and AI. Live CBS statistics, BAG buildings, and spatial analysis at your fingertips.
Ask a question in plain Dutch — AI picks the right datasource (CBS, BAG, NGR), you draw a bounding box, and data is fetched live as H3 hexagons at 174 m resolution.
Van beschrijven naar verkennen: stel wat-als vragen, identificeer conflictzones en vergelijk gebieden op H3-hexagonkaarten. Geo-GraphRAG aanpak met expliciete aannames en Woo-conform redeneerlog.
Stel zelf ruimtelijke normen in voor groen, geluid, overstroming en bouwkansen. Zie direct welke gebieden in uw gemeente voldoen — zonder AI, volledig transparant en stap voor stap.
