Cultural landscapes are those that are shaped through the combined forces of cultural and natural activity, typically over a long period that may reach back to historic and prehistoric times. Amongst these, the documenting, modelling and visualisation of cave landscapes have always been particularly important for scientific communities such as speleology. In the current state of the art, terrestrial laser scanning provides a level of documentation of objects whose accuracy cannot be achieved by conventional methods. In addition to the highly accurate metric and geometric information, visual information brings incredible richness to the presentation of data. Virtual reality (VR) allows individuals to immerse themselves within virtual environments to explore monuments and other cultural heritage sites up close. More and more, VR systems are available at lower prices and are not only limited to VR labs. In this paper, we present research on the generation of a virtual 3D model of the İ...

Recent advances in contemporary Virtual Reality (VR) technologies are going to have a significant impact on veryday life. Through VR it is possible to virtually explore a computer-generated environment as a different reality, and to immerse oneself into the past or in a virtual museum without leaving the current real-life situation. For such the ultimate VR experience, the user should only see the virtual world. Currently, the user must wear a VR headset which fits around the head and over the eyes to visually separate themselves from the physical world. Via the headset images are fed to the eyes through two small lenses. Cultural heritage monuments are ideally suited both for thorough multi-dimensional geometric documentation and for realistic interactive visualisation in immersive VR applications. Additionally, the game industry offers tools for interactive visualisation of objects to motivate users to virtually visit objects and places. In this paper the generation of a virtual 3...

Documentation in maintaining cultural properties is a highly important stage of work for determination of the unique properties. The researches having been carried out over years to increase the accuracy of documentation enabled it to reach such a point that the properties can be scanned by 3D laser scanners today. In order for the lost parts of the civil architecture examples required to be preserved in the context of cultural texture to be found and reconstructed, precise measurement have gained importance in documentation of the current status. Over years, major losses have arisen in the cultural texture situated around Erzurum Castle where the unique architectural examples are placed together. In this study, the importance of the 3D documentation in preserving the cultural properties is discussed in the context of Zırnıklı Vehbi Bey Mansion situated near to the Castle. The CAD drawings of this structure which has significantly lost its spatial integrity has been generated from t...

Determination and documentation are the basis of all studies in the context of conservation and sustainability of cultural heritage. Considering the number of historical and cultural properties and their deterioration status, the fastest and most accurate method of documentation is required to be used in these studies. With the development of technology, traditional documentation methods have been replaced by digitization which enables the acceleration of the whole process. 3D laser scanning technology is the most rapid, accurate (metric) and reliable method used in digitization studies of cultural properties / cultural heritage nowadays. By using laser point cloud data, 3D model of cultural properties can also be generated quickly and in detail as well as documentation and digital archiving. At this point, the integration of digital camera or 360 ⁰ panoramic camera, which is very popular today, and point cloud data makes a significant contribution to further analyzes. This study expresses the 3D digitalization processes of the Suleymaniye Külliye (Mosque and Complex), which is included in the UNESCO World Heritage List. 3D model and VR applications, which are also outputs of the study, are discussed at the end part.

Cultural heritage monuments are ideally suited both for thorough multi-dimensional geometric documentation and for realistic interactive visualisation in immersive VR applications. Additionally, the game industry offers tools for interactive visualisation of objects to motivate users to virtually visit objects and places. In this paper the generation of a virtual 3D model of the Selimiye mosque in the city of Edirne, Turkey and its processing for data integration into the game engine Unity is presented. The project has been carried out as a cooperation between BİMTAŞ, a company of the Greater Municipality of Istanbul, Turkey and the Photogrammetry & Laser Scanning Lab of the HafenCity University Hamburg, Germany to demonstrate an immersive and interactive visualisation using the new VR system HTC Vive. The workflow from data acquisition to VR visualisation, including the necessary programming for navigation, is described. Furthermore, the possible use (including simultaneous multiple users environments) of such a VR visualisation for a CH monument is discussed in this contribution.

Restitution Projects which enable us to show the autentic properties of historical buildings, give us an important reference for the related restoration projects. During the restoration process of Sepetciler Kasr, restitution studies had a similar importance. Sepetciler is the only shore palace left from the Topkapı Complex and has a perfect location at the Haliç entrance. The allocation of this Kasr to the Agency of Đstanbul 2010 European Capital of Culture in 2009, brought renovation attempts and detailed project studies into the agenda.In Sepetciler case we can differentiate several historical periods. For example it has Byzantion Towers from 9th Century, city walls from 11th.century , a substructure from 17 th. century and finally a totaly new sight gained in 1990's. In Sepetçiler building, the coexistence of these older and newer construction elements in a new combination was an important factor which complicated restitution studies. Because of this property, every single detail of the building was analyzed and the authentic parts were differentiated according to their period. During the restitution studies, we reached some documents about how was the situation of the building in 17th. century and by using this data with the one's we gathered from the building itself, we proposed 3 alternate restitution projects, every one of which are based on different historical periods of the building. ÖZET Kültür varlıklarının yapıldıkları dönemdeki özgün hallerinin ortaya konmasını sağlayan restitüsyon projeleri yapının restorasyon projesi için önemli bir altlık teşkil etmektedir. Sepetçiler Kasrı proje sürecinde de restitüsyon çalışmaları ise ayrı bir önem taşımaktadır. Sarayburnu'nda Haliç girişine hakim bir noktada bulunan Sepetçiler Kasrı Topkapı Sarayı'nın günümüze ulaşan tek sahil sarayıdır. 2009 yılında Đstanbul Avrupa Kültür Başkenti Ajansı'na tahsis edilmesiyle gündeme gelen onarım çalışmaları, ayrıntılı bir proje çalışması yapılmasını gündeme getirmiştir. Sepetçiler Kasrında pek çok tarihsel dönem bir arada görülebilir. M.S.9.yy Bizans'ından kalan kuleleri, 11.yy'a ait deniz surları ile 17.yy dan kalan alt yapısı ve 1990larda kazandığı yeni görüntüsü. Yapıda ilk dönemden kalan yapı elemanlarıyla sonradan eklenenlerin kaynaşmış bir şekilde birarada bulunması restitüsyon çalışmalarını zorlaştırıcı önemli bir etken

Documentation in maintaining cultural properties is a highly important stage of work for determination of the unique properties. The researches having been carried out over years to increase the accuracy of documentation enabled it to reach such a point that the properties can be scanned by 3D laser scanners today. In order for the lost parts of the civil architecture examples required to be preserved in the context of cultural texture to be found and reconstructed, precise measurement have gained importance in documentation of the current status. Over years, major losses have arisen in the cultural texture situated around Erzurum Castle where the unique architectural examples are placed together. In this study, the importance of the 3D documentation in preserving the cultural properties is discussed in the context of Zırnıklı Vehbi Bey Mansion situated near to the Castle. The CAD drawings of this structure which has significantly lost its spatial integrity has been generated from the 3D laser point clouds, then the restitution and the restoration projects of the monument have been prepared accordingly.

The first step of the conservation action, which defines all the operations to “preserve the authentic qualities" of a building or property, is "to understand the object, to collect data about its physical condition before any action or intervention that can change it" (URL4, Operational Guidelines of World Heritage Sites, 1998). The purpose of the conservation action is to “preserve the authenticity”. The first step is to record the “current status of the heritage”. Over the years, research to increase the sensitivity of documentation has led to the use of these technologies together and to the point of scanning the entity with 3D laser scanning devices today. The Registered Civil Architecture Examples around the  Erzurum Castle were documented and conservation projects were designed within the scope of the Cultural Road Project, which is planned to be carried out in order to protect, sustain and economically evaluate the immovable cultural heritage, which are considered the most important values of cultural identity.
