The study is aimed at investigating environmental topography at 2018 Taichung flora exposition and surrounding areas by use of Unmanned Aerial Vehicle (UAV) and airborne Light Detection And Ranging (Airborne LiDAR). The practical surveys were carried out over Houli area with a location 120°43'20'W-120°45'00'W and 24°17'15'N-24°18'20'N in February, 2014. UAV is applied to obtain a Digital Surface Model (DSM) with a spatial resolution of 10cm, and LiDAR is adopted to acquire both DSM and Digital Elevation Model (DEM) with resolutions of 1m. The theories and experiments of UAV and LiDAR are both entirely described. Topographic slopes, topographic slope aspects, and environmental hydrology of the area are precisely computed and analyzed. The elevations in the study area vary from 200 to 400m, and increase gradually from west to east. In addition, natural woodlands with tree height of 14~25m are averagely distributed in Eastern part, which mostly contains hilly and mountainous terrains. We hope that the results are able to be taken as references for planning and design of 2018 Taichung flora exposition.
