Modern remote sensing methods like photogrammetry and photoclinometry, LIDAR, laser altimetry, etc., allow the quantitative characterization of outcrops and geomorphological features, offering new opportunities to model geological structures in 3D. These techniques have been successfully applied, at different scales, to outcrops on the Earth's surface, terrestrial planets, satellites and minor bodies in the Solar System. We solicit contributions to this session on remote sensing technologies, geological interpretation and structural modelling strategies, and 3D studies carried out on terrestrial and extraterrestrial structures, aiming at bringing together experiences from different science communities.
