The data consist of four cm-resolution orthophotos and digital elevation models (DEMs) derived from four drone photogrammetric surveys conducted on 23 July 2022, 18 November 2023, 25 April 2024 and 20 August 2024. The drone images were processed using Agisoft Metashape software to generate products for structural mapping and temporal comparison. The drone data evidences fracture reactivation processes and associated new surface fractures and sinkholes. The dataset includes maps of these structures, carried out using QGIS, and describes their temporal evolution. A full description of the data can be found in the file description.
