Discovery of archaeological sites through Lidar in Picardie

Published in Archaeology

  • Client: SRA de Picardie
  • Domaine: Archéologie
  • Moyens utilisés: LIDAR aéroporté

Applied to the Lidar technology, the Magsalia process allows an in-depth study of a site, without even degrading the surface.

The process’s field experience shows Magsalia increases by a factor of 10 the sensitivity of the sensors and allows to characterise buried objects at depth of 20 cm below the ground surface. Coupling Lidar with Magsalia has allowed the locating, under the forest cover, of a tumulus with a circular ditch and an oppidum.
