(Konya Technical University Faculty of Architecture and Design, 2012) Belli, Gianluca; Bonora, Valentina; Guardini, Nadia; Güleç Korumaz, Saadet Armağan; Tucci, Grazia
1.1any technologies have been used in cultural heritage conservation and documentation in recent years. üne of these techniques, laser scanning which is increasingly becoming popular in late years is used for various purposes like surveying, modelling, archiving and visualization in the field of cultural heritage. Plenty of works have been done in heritage documentation with laser scanning technique allowing the user to achieve different information from a 3D model and helping to investigate the shape and components of heritage. This paper deals with how a 3D model can be used to identify the construction technique of heritage and the application of laser scanning for the generation of 3D models of the vaults in Sangallo's House in Firenze. The aim of this study is to compare the shape and the constructive techniques of surveyed vaults. To achieve this aim, we needed to obtain the thickness and the morphology of the vaults, and this information was provided by laser scanner survey. The paper presents applied technology and instruments used, steps of graphical evaluation and 3D, comparisons between the vaults. In order to make comparison, detailed surface modelling was needed to understand them and to be able to see the differences between construction techniques of the vaults. Leica HDS 6000 laser scanner was used for the generation of 3D model of the vaults. Then point clouds were registered in Cyclone. After that, cross sections were extracted from 3D model to understand vault thickness, shape and to have an idea about how they were built. The results will be displayed and evaluations will be made as conclusion.
Geomatics: New Technologies for an Innovative Planning Approach
(Konya Technical University Faculty of Architecture and Design, 2014) Tucci, Grazia; Bonora, Valentina
The paper discusses the technical and cultural evolution of the approach to environment, landscape and cultural heritage, providing a short review of the international charters, recommendations and conventions focused on those themes. It presents some innovative ways for collecting 3D metric documentation, such as digital photogrammetry from UAV systems and mobile mapping, since 3D models are widely used in cultural heritage to create accurate records of individual monuments and buildings as well as complete sites, and they are of great interest both for research and for dissemination purposes. The topic of the re-use and promotion of digital cultural resources is proposed as a challenge for the near future.
Ict Project for the Museum of Casa Martelli in Florence, Italy: for a Virtual Tour of Today's and Yesterday's Collections
(Konya Technical University Faculty of Architecture and Design, 2012) Cini, Daniela; Bonora, Valentina; Tucci, Grazia
Through the use of multimedia centered on imaging technology, three-dimensional survey and customized educational itineraries, a noble ancient palace with its relevant art collection becomes a very communicative museum. This paper presents the project plan and first achievements, featuring the objectives, the explorative tools and impacts on visitors and users. The purposes of the project are to reconnect threads between artworks and documentary sources, which have been cut or forgotten, and to reveal to the museum 's visitors the lost evidence of these links, either attested to by dire et figurative references or by art-historical reconstructions. The technical aspects of the planned paths for different kinds of visitors are m eant to engage the users and make their cultural experience unique and personal: both the applications on site and through the Web will broaden the visitor's perspective providing information, suggestions and stimuli for an integrated and accurate perception of all elements related to the family's collections and home.
New Technologies for Cultural Heritage Documentation and Conservation: the Role of Geomatics
(Konya Technical University Faculty of Architecture and Design, 2012) Tucci, Grazia; Bonora, Valentina
The concept of Cultural Heritage is rapidly evolving, connoting the union of an intrinsic and an extrinsic value that includes several economic, territorial, environmental, academic and social aspects. The terrible natura! disasters ( cyclones, cloudbursts, floods, landslides, volcanic eruptions and earthquakes) that periodically occur weaken our fragile cultural heritage, which is constantly exposed to risk factors. Failing to protect it has negative effects on the sectors mentioned above, as we know that far some of these phenomena the anthropic action (i.e. pollution, improper use) actively contributed to their occurrence. In compliance with this wider view, the scientific and technological research is acting in different fields: from chemical, physical and biological sciences to nanosciences, from the methods of spatial positioning to info sciences.

Opportunities of Geometric Documentation of Historic Buildings With Terrestrial Laser Scanner, Examples From Aksaray/Turkey
(Konya Technical University Faculty of Architecture and Design, 2018) Güleç Korumaz, Saadet Armağan; Tucci, Grazia; Korumaz, Mustafa; Bonora, Valentina
Detailed and accurate measurements can be done by using laser scanning technology compared to conventional methods in documentation of cultural heritage. Accuracy of measured data directly affects the protection of historical buildings and decision-making process. By processing laser scanning data, multipurpose 3d models can be obtained and all work and results can be shared via internet. Moreover, a detailed analysis of the building can be made with this data and it can be transferred to all related engineering and archeological fields. Despite the advantages of this technology, it has not been used widely yet in production of architectural projects. High cost of equipment and data processing software have been seen as main obstacles for widespread using of this technology. As well as, lack of integration of this topic into architectural education and less number of researcher studying in this field restrict the use of laser scanner. In this paper, evaluations were made in order to define the possibilities by using laser scanner technologies in process of restoration projects of which number is getting increased in last decades in Turkey. Positive and negative aspects of technology observed in survey process were given with a case study, a small traditional house in province of Aksaray and some reviews related to potential use of laser scanner technologies were made in Turkey.
Restoration Laboratory Class and the Role of Geomatics in Cultural Heritage Education
(Konya Technical University Faculty of Architecture and Design, 2014) Güleç Korumaz, Saadet Armağan; Korumaz, Mustafa; Bonora, Valentina; Tucci, Grazia
Conservation-restoration education has been discussed in context of teaching methods, curriculums, quality of courses and interdisciplinary relations since Bologna Declaration has started. Conservation-restoration classes are generally devoted to give general knowledge about theoretical background of restoration and to make some practices related to theoretical part with preparation of restoration project. In recent years, innovative technologies have given different opportunities to conservation-restoration practice and its education as well. University of Florence Restoration Laboratory class gives both theoretical and practical courses with innovative approach and interdisciplinary study. In this course GECO3 Laboratory provides methodologies and tools with new techniques in documentation/surveying and analysis of cultural heritage. This support would be very effective for students’ future studies and practices in their professional life. The aim of this paper is to represent an approach to conservation-restoration education adopted by University of Florence, to explain possible integration between different disciplines and to emphasize the significance of geomatics laboratories in conservation-restoration education.
Uav Systems for Documentation of Cultural Heritage
(Konya Technical University Faculty of Architecture and Design, 2014) Güleç Korumaz, Saadet Armağan; Korumaz, Mustafa; Tucci, Grazia; Bonora, Valentina; Niemeier, Wolfgang; Riedel, Björn
Architectural documentation is an activity which requires getting information from different sources for complete and comprehensive analysis. In the field of architectural documentation different innovative systems have been developed in survey like digital photogrammetry and Terrestrial Laser Scanning (TLS). One of these techniques Unmanned Aerial Vehicles (UAVs) equipped with a digital camera have become one of the most promising techniques in last years. It opens various new applications in large scale and close-range and so becoming progressively common due to the considerable potentials in terms of accuracy, costs and abilities. Their capability of data acquisition with high resolution allows texture mapping on DSM (Digital Surface Model), 3D models and orthophotos. It is also possible to create mosaics, maps and drawings which can be used for image interpretation. These data can be applied to several applications including 3D documentation of environment, cultural heritage, monitoring and recording landscape data and infrastructural assets for risk analysis and management process. This paper discusses the potentials of UAVs in order to analyze, interpret and manage cultural heritage data through a case study (carried out before). It also presents the procedure of processing UAV data in order to create digital surface models and photo-realistic outputs for digital reconstruction models and visualization. The obtained results have been demonstrated with case study and general discussion has been made for evaluating potential of UAV technique for cultural heritage documentation.
