Day 10/100: Why hexagons for population density 🔶
Romania at 400m resolution via Uber #H3 hierarchical hexagonal index. Admin boundaries rarely reflect how people occupy space.
Hexagons > squares/triangles: 6 equal neighbors, minimal directional bias, reduced edge effects, circular distance approximation, perfect tessellation.
#QGIS for H3 processing + #Qgis2threejs for 3D export = browser scene with semitransparent hexagonal columns. Height + color encode density.
