The dataset contains the geomorphological units map of the area Irizar - Crater Lake in Deception Island as a shapefile. Mapping was produced using high resolution field mapping and focus on present-day geomorphological processes and on the characteristics of the surface materials. The map was produced with the objective to contribute to analysis of surface deformation products derived from remote sensing imagery and permafrost modelling within the project ESA Data User Element - GlobPermafrost (DUE-GlobPermafrost).
