This dataset comprises a 2-m-resolution digital elevation model (DEM) (WorldView3-DEM.tif) and 0.5-m-resolution orthophotograph (WorldView3-DOM.png) of the West Helanshan Fault (Northern China) which is a Holocene active right-lateral strike-slip fault located at the junction of the Tibetan Plateau, Alashan, and Ordos blocks. The dataset covers a 6 km wide swath along an approximately 50 km long section of the fault (the dataset extent can be found in West_Helanshan_Fault.kmz). The DEM was built from the WorldView-3 panchromatic stereo images acquired on 5 July 2018 based on the photogrammetry method, and the orthophotograph was created based on the generated DEM. Two local areas along the fault are heavily obscured by clouds in the WorldView-3 images. Thus, we used a small four-rotor Unmanned Aerial Vehicle (UAV), the Motoarsky MS670, to acquire images of the two areas on 27 September 2018. Based on the Structure-from-Motion (SfM) method, we finally obtained DEM with a spatial resolution of 0.1 m (UAV-DEM1.tif and UAV-DEM2.tif) and orthophotograph with a spatial resolution of 0.03 m (UAV-DOM1.png and UAV-DOM2.png) for the two local areas.
