Introduction by OpenMethods Editor (Delphine Montoliu): This post updates the capacities of the scanning tool LiDAR for the archeology recognition and the new potential issues for our cultural heritage.

In recent years, LiDAR scanning has become a widely used tool for understanding both the cultural and natural landscape surrounding us. The result of this is, that new 3-dimensional point based LiDAR (Light Detection and Ranging) data is consistently being generated in a more precise and detailed version of raw point cloud form.

 

Airborne laser scan data includes information about the ground surface as well as the existing vegetation allowing to virtually remove for instance forests to reveal hidden structures. Even ground monuments which are heavily eroded and/or very flat can be detected by this approach. (Interpolated) surface models are often used to visualize the findings.
