Notas do Editor
- But we’d assume that in today’s modern world, we’d assume that all of that wonderful tech gets applied to archaeology and pop culture sources speak to this having happened and to science fiction potential for high speed data capture and visualization Bones CSI Prometheus LiDAR balls BUT ITS NOT YET SO- visual data manipulation limited, 3D modelling mostly- one offs- not a systems for entering, storing, and accessing information
- As an archaeologist- approached the initial data collection problems- how can we use laser scanning tech (LiDAR) for quick data collection in excavation and surveying environments Solved certain archaeology specific field issues- Resulted in Enhanced speed
- My trial system at Khirbat Faynan in southern Jordan worked so well that we applied it to a nearby endangered site
- The Birth of Rescue LiDAR: Umm al-Amad
