## 7 Final Remarks  
In the present work we surveyed and mapped geological features using the IVR approach, focusing, as a key site, the Metaxa Mine volcanic area, located in Santorini Volcanic Complex, Greece. We have firstly reconstructed the area in 3D, with centimetric accuracy, using UAV-based photogrammetry. The resulting high-resolution 3D model was used as a VR scenario, imported in GeaVr software, where we mapped the upSper excavation boundary of the mine, the LBA-phases, natural and anthropogenic debris, and we quantified the thickness of LBA-phases all around the vertical cliffs. These data were processed and analyzed in GIS environment in combination with existing ones, providing new DSM, orthomosaic map, thematic maps as well as new results regarding the volume of the excavated material. Finally, we described the Metaxa Mine as a key geosite, and shared the 3D model of the mine as well as the Famous LBA-Section, with the purpose of popularizing them and making them available worldwide, both during COVID-19 times and beyond.
