摘要

To assess the potential of a large-scale landslide, it is essential to obtain geological information for the landslide site through site investigation which may include aerial interpretation, field geology survey, geophysics tests and borehole exploration. However, the implementation of geological surveys usually consumes a lot of time and manpower. The access of large-scale landslide site is often exposed to rugged terrain; it is usually challenging and dangerous to collect geological information in some inaccessible spots such as cliffs and deep valleys. Lately, light-weight unmanned aerial vehicles (UAV) equipped with cameras or image sensors have been widely used because of its high mobility and low cost. In this study, we demonstrate a variety of possible UAV applications for the geological survey in a potential large-scale landslide area. The present work adopted commercial UAV as a site-investigation tool and utilizes UAV-photogrammetry methods to improve the efficiency of geological survey in a large-scale landslide area in southern Taiwan. The produced UAV photogrammetry includes aerial photos, three-dimensional point cloud, digital surface models, and ortho-images. In this paper, we demonstrate four possible applications of geological survey to collect various types of data. These applications include (1) the thickness estimation of colluvium; (2) the orientation determination of outcrop bedding planes; (3) the micro geomorphological features interpretation; and (4) the depth, area and volume estimation of the rainfall event.
