TL;DR: It is suggested that sediment delivery rate decreased each year and was affected by heavy rainfall during each period for the Meiyuan Shan landslide area, and multi-period aerial photogrammetry and ALS can be effectively applied after the landslide disaster for monitoring the terrain changes of the downstream river channel and their potential impacts.

TL;DR: In this article, a morphological reconstruction method was proposed to assess landslide morphology based on the dome-shaped topography of the volcanic edifice and the nature of its morphological evolution, and two large-scale landslides in the Tatun volcano group in northern Taiwan were targeted to more accurately characterize the landslide morphology through airborne lidar and UAS-derived digital terrain models and images.

TL;DR: In this paper, a polygon auto-tracing method for generating dip-slope maps based on airborne Light Detection and Ranging (LiDAR) data and a customized spatial analysis toolset developed in Python is proposed.

TL;DR: A high-resolution 2-ky record of changes in sediment delivery to Dahu, a floodplain lake in northeastern Taiwan, that suggests changes in precipitation has been inferred from organic matter, pollen, and spores in a 12m sediment core and from the organic matter compositions of soil, catchment plants, and fluvial suspended sediment as discussed by the authors.

TL;DR: Li et al. as mentioned in this paper used two types of 3D images which differ in imaging principles to further explore the finer details of sedimentary terrain, and proposed a geological mapping practice that improves efficiency and meets a high-precision mapping standard with up to 2 m resolution using airborne LiDAR data.
