DOCUMENTATION OF CULTURAL HERITAGE THROUGH THE FUSION OF GEOMATIC TECHNIQUES. CASE STUDY OF THE CLOISTER OF "SANTO DOMINGO" (JAÉN, SPAIN)

Abstract. This study describes the methodology and results obtained for the modelling of the cloister of “Santo Domingo” located in the city of Jaén (Spain). The main objective of the application of geomatics techniques to this case was the graphic documentation of the site, the development of HBIM and the diffusion of the results. For this purpose, we developed a methodology based on the fusion of data obtained using several sensors, acquisition techniques and scales. In this sense, we used TLS, RPAS aerial photogrammetry and terrestrial photogrammetry using a spherical camera. As results, we obtained a 3D model with real texture and from this we developed several applications focused on the documentation and diffusion of the results, such as the BIM (HBIM), an interactive virtual tour and a 360 virtual tour available on a website. The proposed methodology has demonstrated its feasibility for performing this type of study due to the results and accuracy achieved with this application. We highlight the potential of current geomatic techniques for documenting this type of cultural heritage regardless of its structure and dimensions, selecting in each case the most appropriate methodology in relation to the scale of the products demanded. In addition, we also emphasize the need to use several techniques and the fusion of their partial products in order to obtain a complete product of the whole scene, taking advantage of the specificities of each one.
