The result is the documentation of an extensive set of mines, which places Lusitania as one of the main gold producing areas of the Roman Empire. These are mainly open-cast mines, which were worked with the help of water. “ https://www.theportugalnews.com/news/2021-07-03/researchers-confirm-existence-of-ancient-roman-gold-mines-in-central-portugal/60839 Summary: So, what is this technology known as Lidar or LiDAR (Light, Detection, and Ranging also called Laser imaging, Detection, and Ranging)?
