Metadata-based heritage sites modeling with e-learning functionality

Abstract

Nowadays, cultural heritage is under threat and danger (pollution, natural disasters, wars, etc.). In this domain, cultural heritage management (CHM) as the art, vocation and practice of managing cultural heritage resources and as a multi-discipline research area has a vital role. In recent years, the innovations, improvements and rapid advances in traditional and geographic (GIS) databases, design computing, digital architecture and archaeology, imaging sensors and scanners, computer modeling software, haptic equipments and e-learning technology, as well as the affordability and availability of many powerful graphics workstations make metadata and 3D modeling techniques for CHM with e-learning and haptic rendering (virtual reality) functionality feasible. This paper addresses the application research issue of incorporating metadata and modeling in a CHM case study and discusses the related e-learning functionality. So, in this article, a practical project is used to demonstrate the functionality and the performance of the proposed 3D modeling metadata based CHM methodology. In particular, the processing steps from image acquisition to the 3D geometric and semantic description of the Galerius Palace "Octagonon" (Thessaloniki, Greece) in a 3D digital environment are presented. Also, emphasis is put on documenting the new term 3D modeling metadata for CHM and on discussing as an open issue the concept personalized elearning CHM scenarios. The proposed methodology has 10 −2 modeling accuracy (i.e. 1% relative inaccuracy) and it is of interest for archaeology, architecture, virtual reality, e-learning, e-culture and virtual tourism.

Exploring Cultural Heritage Resources in a 3d Collaborative Environment

“…There are the conceptual representation, digital representation, and visual representation (Ahonen-Rainio, 2005;Laurini and Thompson, 1992;Worboys, 1995), and all of concern to a user of metadata. We propose a 3D modelling metadata structure based on the previous work carried out by Styliadis (Styliadis et al, 2009). First the data forming the basis of the modelling study are examined as primary metadata, then the principles of both the analysis and the restitution are presented (secondary and tertiary metadata), and finally the hypothesis formulation (fourth level metadata) and following the reconstruction hypothesis formulation (fifth level metadata) are documented.…”

Living in the clouds: conceptual reconstructions of harbour structures

“…However, for use in historic research, education and dissemination, the same operational format is not imperative. Though it has been argued that 'high modeling accuracy' is not required in models for archaeological hypotheses or architectural digital reconstructions (Styliadis et al, 2009), the premise of this paper is that it is accuracy that is paramount in these cases and that it is the need for an operational format that should be reconsidered.…”

(Re)presenting heritage: Laser scanning and 3D visualisations for cultural resilience and community engagement

“…This suggests an approach to the subject where metadata-rich models would extend the data typologies suggested by Styliadis et al [29], which have much in common with physically-oriented building information models, to incorporate qualitative and socially-driven information. Cultural assets can exist across a spectrum from 'high culture', recognised and protected in most regions, with cultural historical significance to that of vernacular or industrial structures, which can equally provide insights into the societies and culture from which they emerged and in which they are part of the ongoing development of place specific cultural urban identities as basis for cohesion and communities [30].…”
