- Resumen
The thesis focus in the central idea of Digital Representations and the Valuation of Cultural Heritage, in the relation between Technology, Agents and several knowledge Domains, seeking to analyse the Augmented Valuation of Cultural Heritage, based on Geographic Information Technologies (GIT). It introduces the significance of (digital) representations through the concepts of the individual¿s spatial cognition (internal/mental representations) and physical (external) perceptions and their epistemological importance, revealing what are the GIT contributing to these representations: Global Navigation Satellite Systems (GNSS), Remote Sensing (RS), Geographical Information Systems (GIS), 3D data Acquisition, Modelling and Visualisation and Virtual/Mixed Environments.
The methodology consists of point clouds (x,y,z) data acquisition using terrestrial and Unmanned Aerial Vehicles (UAV), 3D modelling procedures, integration between 3D-GIS and virtual environments applied to cultural heritage systems and elements in urban areas. The results consist of geographical information products and 3D acquisition and modelling processes to be visualised in an Augmented Reality environment, through mobiles platforms. It was discussed experiments using mobile applications (App) available in the market that have enabled the adjustment of core solutions for further development of the App Lx_W, consisting in the related Apps: AqueductAR and AqueductGPS.
Selecting the ancient Lisbon (Aqueduct) water supply system (classified as a national monument in 1910) as a case study and considering the fact that most of the structure is unnoticeable, due to the large extent of underground galleries, these types of synthetized enhanced environments enable onsite visualisation and the perception of the relation between the system and the city. The prototype of Lx_W App was evaluated during the workshop with the purpose of analysing the application that had been developed using the answers obtained in survey, relating this App and some experiments carried out with other Apps available in the market. A second survey was conducted supported by a video where the heritage system and the Lx_W App were introduced, showing the App¿s features and capabilities applied to this specific case study.
The methods used aimed to strengthen the idea of the potential application of this technology for heritage valuation, introducing the concept of Augmented Valuation of Cultural Heritage, associating the use of geographic information to fields commonly related to a strong visual perception of space, providing essential data to the Agents, not only for occasional users (public), but also for specialised technicians, opinion/decision makers, promoters and other stakeholders, addressing solutions (or contributions) to the existing problems in the several technical-scientific, socio-economic, political-administrative, ideological-symbolic-religious Domains.
