文摘
- •
An unmanned aerial vehicle (UAV) is employed to autonomously collect nadir aerial photographs with sub-centimetre resolution.
- •
Digital photogrammetry is used to compute a high-resolution orthophotograph and a dense 3D point cloud.
- •
Digitally extracted bedding orientation measurements are used for 3D implicit modelling and bulk shortening strain estimation.
- •
Systematic fracture sets in basement and cover rocks are digitally traced on high-resolution orthophotographs and compared.
- •
Data suggest that one set of fractures is inherited from preferentially oriented upright folds and reverse faults in the basement.
