Editing Photogrammetry (section)

=== Rock mechanics ===
High-resolution 3D point clouds derived from UAV or ground-based photogrammetry can be used to automatically or semi-automatically extract rock mass properties such as discontinuity orientations, persistence, and spacing.<ref>{{Cite journal |last1=Tomás |first1=R. |last2=Riquelme |first2=A. |last3=Cano |first3=M. |last4=Pastor |first4=J.
