Title: Application of Digital Aerophotogrammetry in Active Tectonics
Abstract: In order to efficiently obtain high-quality quantitative parameters in active tectonics research, it is necessary to introduce digital aerophotogrammetry as a surveying and mapping tool. Testing research was performed along the Xianshuihe fault zone, which is located in the mountain area of western Sichuan Province. Using spatially enhanced, orthorectified images, large scale topography and ground surface profiles, we obtained a series of data of the active Xianshuihe fault zone near Tuanjie in the south of Kangding county. Left lateral horizontal deformation of the fault is about 43m and vertical deformation is about 5.8m since the T1 proluvial fan was formed. Digital aerophotogrammetry provides high precision when measuring quantitative parameters in the study of active tectonics such as accumulative horizontal and vertical deformations and fault length, detailed geometric structure resolution and geomorphological mapping, thus greatly improving field work efficiency.
