This dataset contains 3D point clouds (raw data) from TLS measurement of valley walls and talus deposits beneath them in the Lauterbrunnen Valley, Switzerland. The point clouds of valley walls were collected as part of an ongoing monitoring study of the valley walls since 2012. The data files included here are those that have been used for talus volume calculations which were used for calculating the long-term (~11 ka) wall retreat rate (Mohadjer et al., in review ).
