Day 7: Taal Volcano PHIL-LiDAR at 1 m, processed with PDAL for morphology and hazard context. Week 1 of GIS foundations closes here. #100DayMapChallenge.
Day 5: Point Clouds Cross Borders – Dublin LiDAR (2020)
Day 5: NYU Dublin LiDAR, 500M+ points, same PDAL pipeline as Yosemite in an urban context. Geography is local. The tools are global. #100DayMapChallenge.
Day 3: Nearly 25 Million Points in a Single File – PDAL Yosemite
Day 3: PDAL and Entwine on Yosemite Valley LiDAR. 570 million points, JSON pipelines, Potree visualization. Processing took 19 hours. #100DayMapChallenge.
Day 2: Mapping Walls You Can’t See From Above – Yosemite LiDAR
Yosemite Valley climbing walls from 0.5 m airborne LiDAR: slope analysis above 75°, flow direction for wall height, yellow-to-red classification. Day 2 of #100DayMapChallenge.
LiDAR PDAL Experiments – Dublin
Those are my notes on taking some LiDAR data and testing different commands in PDAL. If you like, you can follow along using your own data. Most probably I’ll de adding or deleting stuff, but you can take a look…
