Georadar Exploration of the Pilat Dune, France

Proceedings, 2014
The Pilat dune presents four principal paleosol (apparing at the surface) that have been dated by Carbon-14 analysis or Optical Stimulated Infrared Luminescence (OSIRL). Anyway, no quantitative information about the evolution of the paleosols within the dune is presented in literature.

Automated three‐dimensional georadar acquisition

SEG Technical Program Expanded Abstracts 1997, 1997
A self-tracking laser theodolite with automatic target recognition capabilities has been adapted to serve as a real-time positioning system for the acquisition of three-dimensional (3-D) georadar data. This surveying system provides complete coordinate information with high accuracy.
