Article Citation - WoS: 7Citation - Scopus: 6Documentation of Historic Structures for the Assessment of Heritage Characteristics(Locke Science Publishing Company Inc., 2011) Turan, Mine; Akbaylar, İpekCorrect identification of heritage characteristics is a prerequisite for the conservation of historic structures. This study summarizes the developments in image-based documentation techniques and explores a way of combining them with conventional documentation techniques for architectural conservation. The processes of architectural photogrammetry and pictorial photography help the architect-conservator examine the many details of architectural heritage, making the assessment of heritage characteristics easier. Nevertheless, site observations and historical research are indispensable tools that support the evaluation process. A 19th centwy Ottoman church in western Turkey has been documented by combining the above techniques. Scaled drawings, a 3D model, maps on rectified image mosaics, and image albums make it possible to perceive the spatial qualities and conception of the original construction techniques, together with their alterations. The assessment results are presented in thematic tables with links to visual documents, and the heritage values and conservation problems of the church are clarified. Finally, this study illustrates one example of a successful heritage assessment leading to a conservation design.Article Citation - WoS: 31Citation - Scopus: 41Metadata-Based Heritage Sites Modeling With E-Learning Functionality(Elsevier Ltd., 2009) Styliadis, Athanasios D.; Akbaylar, İpek; Papadopoulou, Despoina A.; Hasanagas, Nikolaos D.; Roussa, Sotiria A.; Sexidis, Lazaros A.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 e-learning 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.
