Raw Data Examples for Close-Range Photogrammetry of Replicative Experiments on Ground Stone Tools

The data presented in this study pertains to the experimental collection built to verify the applicability of close-range photogrammetry to ground stone tools (GSTs).

GS17 is a sandstone slab collected from the Fiora River in Manciano, Italy, where sandstone of Miocene formation outcrops. This stone is primarily composed of quartz grains embedded in abundant carbonate cement. It was utilized as a GST in replicative experiments, paired with an active tool from the same provenience, and subjected to 2 hours of Rumex crispus achenes grinding. Photogrammetric techniques based on Structure-from-Motion and Multi-View Stereo reconstruction were employed to generate the 3D models of the tool at different stages of the replicative use. We recorded the geometry of the GST before (referred to as T0) and after use (T4) to later compare and assess the change in object geometry during the transformation of vegetal resources, thereby facilitating our understanding of archaeological tools.

This dataset comprises the pictures required for the elaboration of the GS17 models at T0 and T4, as well as the data necessary for calibration.
