[ABSTRACT] The purpose of this study is to develop an efficient method to utilize high-definition topographic data by lidar or SfM-photogrammetry for applications in forestry and geomorphology. Here we report a case study at a small headwater channel, in which tree inclinations are found to be affected by surrounding geomorphlogical conditions. We used multi-temporal 3D point cloud data in 2005 and 2016 to reveal the spatio-temporal changes of the tree shape and landforms. Further applications of morphological investigations of tree shapes are expected to be applied in other areas where geoenvironmental changes are predicated.
