The 3D characterization and modelling of geological and geomorphological structures on the Earth, terrestrial planets, satellites and minor bodies in the Solar System poses common problems to different science communities. We solicit contributions in two main fields: (i) remote sensing techniques (e.g. photogrammetry, photoclinometry, LIDAR, laser altimetry) allowing the quantitative characterization of outcrops and geomorphological features, and (ii) innovative 3D interpretation and modelling strategies allowing to obtain new or (more) quantitative results on terrestrial and extraterrestrial structures.
