Historical Digital Surface Models and Surface Roughness Maps from the Palomares and Llano del Águila Faults (Eastern Betics)

This repository stores the Digital Surface Models (DSMs), the GCPs used for each DSM, and the corresponding Surface Roughness maps generated in: Digital Surface Models Derived from Historical Aerial Imagery in Highly Anthropized Areas Applied to Active Fault Studies (Eastern Betics, Spain). The datasets correspond to the Palomares Fault (PF) zone and the Llano del Águila Fault (LLAF). The imagery used derives from the American B-series Flight (AmB) and the Interministerial Flight (InM). Data: DSM files: AmB-PF.tif, InM-PF.tif and InM-LLAF.tif Surface Roughness files: R_AmB-PF.tif, R_InM-PF.tif, R_InM-LLAF.tif and surface_roughness.pdf GCPs files: GCPs location (GCPs_location.pdf) and GCPs coordinates (GCPs_AmB-PF.txt, GCPs_InM-PF.txt, GCPs_InM-LLAF.txt) Coordinate reference system (CRS): ETRS89 / UTM zone 30 For details on processing methods and further information, please refer to the associated publication: Molins-Vigatà, J., Blanch, X., Martín-Banda, R., García-Sellés, D., Gómez-Novell, O., García-Mayordomo, J., Insua-Arévalo, J.M., Ortuño, M., 2026.
