Lidar-derived dems for geoarchaeological investigations in alluvial and coastal plains

Here we present some Digital Elevation Models (DEMs) produced from airborne laser altimetry in the distal sector of the Venetian-Friulian Plain. The research considered some areas where the high detail of the surface landforms allows to evidence the occurrence of some ancient anthropogenic features that normally are not detectable in the present landscape or have been eroded by recent human activity. Case studies are selected from NE Italy, but this work shows the potential of the use of LiDAR data for geoar-chaeological and geological mapping in alluvial environments.
