Volcano Watch – A Cloud of Ten Thousand Points: Terrestrial Laser Scanning of Halemaʻumaʻu
The modern workhorse for ground surveying is terrestrial laser scanning (TLS) using light detection and raging (LiDAR) instruments. LiDAR may sound familiar to longtime “Volcano Watch” readers, because the basic technique was described in a November 2020 article that discussed an aerial LiDAR survey at Kīlauea. TLS surveys are similar, with a ground-based instrument emitting laser pulses and measuring their return times after reflecting off topographic features.
