Innovative Methodology for Personalized 3D Representation and Big Data Management in Cultural Heritage

Three-dimensional (3D) visualization is an effective way not only to study but also to disseminate the built environment particularly the one of the cultural heritage (CH). The extended growth of the technical means have enabled standardized methods for (semi) automatic 3D model production motivating more and more researchers from various backgrounds (e.g. material scientists) to integrate the aspect of 3D modeling within their work despite the certain limitations concerning the amount and types of the data that have to be managed. In order to facilitate the needs of data management, a scalable, interactive, web-based platform is proposed within this work. The case study over which the proposed methodology has been implemented is the recently rehabilitated Holy Aedicule of the Holy Sepulchre in Jerusalem due to the vast amount of heterogenous data produced for the needs of monument's documentation before and during rehabilitation. To address this issue, the present study will provide the missing layer that enables the semantic data labeling, through data processing and filtering, and their spatial representation - visualization. Additionally, a straightforward methodology for affordable but of high quality and precision modeling of cultural heritage data and its exploitation towards the delivery of personalized content is achieved. As a result, the derivative georeferenced high-resolution 3D models are transformed resulting in a multi-resolution model management which under the appropriate configuration of the JavaScript components on an interactive web platform.
