The dataset consists of the original top-view and cross-section digital photographs of the model presented in Broerse et al. (2020) (Mappingand classifying large deformation from digital imagery: application to analogue models of lithosphere deformation.). The top-view images have been taken at a regular interval of 45 seconds during the entire experiment. Cross-section images have been taken after the experiment was finished. The purpose of the top-view images is to track incremental displacement fields of the model surface in time, estimated by Particle Image Velocimetry (PIV) based on the digital images. The cross-section images serve to inspect the final internal deformation along vertical planes.
The images are located in two folders; top-views contains the full range of top-view images as used in the PIV analysis, starting at the original undeformed state until the final deformed state at the end of the experiment. A sub-folder not used in PIV contains images from before the start and after the stop of the experiment, and that are not used in the accompanying manuscript. The folder cross-sections contains an overview image of the locations of all cross-sections taken (IMG 7243) and images of vertical model cross-sections. In total 13 cross-sections have been made, where the cross-section numbering starts from the north, and continues southward (see image IMG 7243). The cross-sections a-a’, b-b’ and c-c’ that are used in Broerse et al. (2020) correspond to numbers 2, 6 and 13, respectively. The cross- section images have been taken with a southward view, while in Broerse et al. (2020) we have mirrored the images to present a northward view on the cross-sections. All photographs are in .jpg format and their names are original generic names created by the camera software at the moment of acquisition. Contact person is Taco Broerse - D.B.T.Broerse@uu.nl
