The GESYP (Geovisualization of Singular Spaces and Heritage) is working in this area since 2005 and has published several studies (https://www.youtube.com/watch?v=8YT4BkLi0EY and https://www.youtube.com/watch?v=2BYjJ-Lebn8), articles (“Assessment of underground wine cellars using geographic information technologies” (https://doi.org/10.1179/1752270614Y.0000000104), “Characterization of Cavities Using the GPR, LIDAR and GNSS Techniques (https://doi.org/10.1007/s00024-014-0985-6) and others), and phd thesis (http://oa.upm.es/30463/) around these underground cellars of El Plantio in Atauta (Soria). This area was declared an Asset of Cultural Interest (Bien de Interés Cultural, BIC) in March 2017, which represents a unique testimony of the life associated with work on the land and the traditional wine production system. In the different researches made by GESYP, the most innovated geomatics techniques in geomatics like Global Navigation Satellite Systems (GNSS), Terrestrial Laser Scanners (TLS), Unmanned Aerial Vehicles (UAV), Ground Penetrating Geo-Radar (GPR) or others were used to obtain in internal and external 3D Models of these cellars even other constructions as pigeon houses to recreate and recover this important, historical and recognized rural landscape in the Duero Basin.
In this study, there has been used a combination of Pegasus backpack-mounted mobile scanning system (MMS) and a Mavinci fixed-wing drone (UAV) to register the surface ground over the cellars. The possibility to evaluate the structural situation of the cellar roofs and the ground that cover them was an interesting target for this study. In a first instant, the researchers analyzed the data captured of both methods to stablish the precision and resolutions that could be achieved. Both systems showed different behaviors depending on their configuration and registration processes but precisions of 5cm in height in a short distance from the tracks of the MMS was achieved and similar results were obtained with UAVs. This precision was significantly reduced when the distance increased from 7.5 to 15 meters of width as demonstrated in the paper.
These first results were compared in order to define a final ground surface but the limitation of both systems in terms of obstacles and irregularities of the ground were found in this type of complex terrain. These limitations were understood such as an opportunity to combine both techniques in order to acquire and unique model of surface that combines both techniques part of the limitations found.
In the second part of the study, it was studied parameters such as the distance to the scanning point, the angles of incidence with regards to the ground, or the study of irregularities in the terrain. As a result, the combination of both data into a new model has been demonstrated as an improvement for their limitations, trying to keep the original precision of both systems by mean a selection of the points that came from the best registers of both systems.
The use of new technologies of capture like MMS or UAV reduce the cost and time of registration and allow the improvement of knowledge of the status of this kind of high value heritage areas. The use of this type of systems allows the guarantee of the conservation of important spaces such as the underground cellars of El Plantío in Atauta and what it is more important, give us better information for their recover possibilities.
