This dataset consists of 3D point clouds acquired via UAV laser scanning (ULS) of a forest plot in the Black Forest in Hundseck, Germany. The plot was captured under snow conditions in January 2021, and the acquisition was repeated under snow-off conditions in February 2021. Additional terrestrial laser scanning (TLS) point clouds were acquired as reference. Details about the acquisition and preprocessing are described in the documentation. The data can be used to assess snow depths in the observation period, as well as the topography and vegetation structure.
