Hyperspectral outcrop models for palaeoseismic studies
The Photogrammetric Record, Volume 34, Issue 168, Page 385-407, December 2019., 2019 To overcome the limitations of the traditional study of palaeoseismic trenches, a new workflow is presented that integrates infrared hyperspectral and photogrammetric data. This method was applied on two palaeoseismic trenches excavated across a post‐glacial fault scarp in northern Finnish Lapland.
