Day 6/100: Antarctica doesn't look like this ❄️☁️

200m elevation data rendered as fluffy clouds in Three.js
QGIS → Three.js fly navigation + transparent texture = cloud-like appearance

Sometimes looking at data in an unfamiliar way reveals patterns you wouldn't notice otherwise.

Day 5: Point clouds cross borders 🌍

NYU captured Dublin LiDAR. I processed 500M+ points using PDAL years later.
NYC captures. Romania processes. Anyone explores.
Geography is local. Tools are global.

Day 3/100: 25M points. Where to start?

FOSS4G 2019: PDAL/Entwine demo. Hooked.

Filter early → lose detail Filter late → noise corrupts

570M points, 19h processing Open-source, documented

Tutorial = order Scale = patience
