In September the ZP&M team has been in the field with the CERENA-IST team to support the PhD research of André Texugo on the archaeology of 5K BP human settlements in the Estremadura region. The team has been surveying several archaeological sites were dense vegetation induces major limitations for terrain analysis. The use of a drone-based LiDAR will allow to mitigate the vegetation effects and improve the 3D mapping of the sites.
