Abstract:The Unmanned Aerial Vehicle (UAV) photogrammetry method has been widely used in various applications. One of the potential photogrammetry methods is to estimate the land deformation, e.g., land subsidence. This study aims to analyze the opportunity of UAV photogrammetry utilization for detecting the land subsidence urban areas, including relatively low cost and wide area coverage in a relatively short time. Two photogrammetry measurements were conducted in two different epochs with different flight altitudes t… Show more
