3D Information System of Historical Site – Proposal and Realisation of a Functional Prototype
Acta Polytechnica, 2005
The development of methods for 3D data acquisition, together with progress in information technologies raises the question of creating and using 3D models and 3D information systems (IS) of historical sites and buildings. This paper presents the current state of the “Live Theatre” project. The theme of the project is the proposal and realisation of a 3D IS of the baroque theatre at Eeský Krumlov castle (UNESCO site).The project is divided into three main stages – creation of a 3D model, proposal of a conception for a 3D IS, and realisation of a functional prototype. 3D data was acquired by means of photogrammetric and surveying methods. An accurate 3D model (photo-realistic, textured) was built up with MicroStation CAD system. The proposal of a conception of a 3D IS was the main outcome of the author’s dissertation. The essential feature of the proposed conception is the creation of subsystems targeted on three spheres – management, research and presentation of the site. The functio...
DEVELOPMENT OF A 3D INFORMATION SYSTEM FOR THE OLD CITY CENTRE OF ATHENS
The representation of three dimensional city models has been gaining ground increasingly in many scientific fields in the recent years. 3D City Modelling is a scale representation of natural and artificial objects in order to present the spatial data and highlight the social development of the city. Depending on its importance or the purpose of use, an object can be represented in various levels of detail. An increasing tendency to 3D city models is their integration into GIS, which proves to be an effective tool for managing, analyzing and planning in order to make decisions about technical, administrative and financial matters. A combination of digital photogrammetric techniques and laser scanning data contribute greatly to this, since a variety of data, such as aerial, satellite and terrestrial images, point clouds from airborne and terrestrial laser systems, and also a variety of photogrammetric and mobile mapping methods are available. The objective of this paper is the development of a 3D Information System (IS) for the three-dimensional geometric documentation of the buildings owned by the Ministry of Culture in the old city centre of Athens, Greece, named "Plaka". The area has been inhabited continuously since the prehistoric era, it has a special architectural style and includes a number of unique cultural heritage monuments. The data used for the reconstruction of the 3D model of Plaka consisted of aerial and terrestrial images, while raster, vector and descriptive data were used for the creation of a 2D GIS, which served as the background for the development of the 3D GIS. The latter includes all of the qualitative and quantitative information related to the 3D building models owned by the Ministry of Culture according to users' needs. Each building in the vicinity of Plaka was depicted in one of the four different levels of detail created for the purpose of the study, according to their ownership status and other criteria. The building models, depicted in the highest level of detail, were owned by the Greek Ministry of Culture whereas the other buildings (of a lower level of detail) were depicted in a more subtractive way. Therefor an integrated IS was developed that combines descriptive information, e.g., use, legal status, images, drawings, etc, with the spatial information and geometric documentation in three dimensions.
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.
Heritage, 2022
Architectural survey is an evolving field in architecture that has been affected during the past decade by the technological advancements in the field of 3D data acquisition. Some of these technological advancements include long-range laser scanning and photogrammetry. Laser scanning gives us an accurate documentation of the site, even in cases where parts of the building have collapsed. This paper aims to present two case studies of digital documentation through laser scanning and photogrammetry that led to the structural reinforcement and preservation of the first site and to a digital reconstruction and a mixed reality platform for the second site. The first site is an Ottoman Soap factory in Lod, Israel and the second one is an Ottoman Bathhouse in Apollonia, Greece. Both sites dealt with challenges during documentation due to a partial collapse of the building or due to dangerous structural conditions. The digital documentation methodologies allowed for a fast, accurate and comprehensive survey, as well as for a good understanding of the building and the areas which were concealed as a result of the collapse. At the same time, the digital documentation model gave the potential for the cultural heritage (CH) site to become part of the social, economic and cultural local community.
An integrated spatial information system for the development of the archaeological site of mycenae
Digital and automated photogrammetric methods and procedures developed for the collection and management of spatial data have been well introduced on archaeological applications. The use of terrestrial laser scanning systems provides new capabilities for 3D visualization of the present situation of a site. Recently, special tools in Spatial Information Systems (SIS) and management systems of virtual world models (VR) have been developed. Their combination can provide relevant scientists and users with a variety of possibilities for the creation of integrated systems capable for documentation, restoration and cultural development of archaeological monuments and sites, with: the detailed 3D documentation of the present condition of the site, the development of a multi-purpose SIS and the introduction of modern digital products at a local museum, such as 3D representations, creation of virtual environment, Web applications. Application of these techniques and systems was made to the archaeological site of the Mycenae, one of the most important sites worldwide. Photogrammetric procedures and laser scanning were used for the data collection. Airphotos were taken by helicopter and a large number of terrestrial photos by analogue and digital cameras. Orthophoto production for the site and detailed 3D vector restitutions, horizontal plans, facades and sections were made. In addition 3D views of vector data and textural scenes were produced by automated procedures. The development of the SIS is based not only on the data and products of the photogrammetric processing, but also on various other data sources, as the structure of the system contains historic, archaeological, architectural and technical information, with texts, digital images (recent and old pictures, old graphic representations etc.), video, 2D or 3D views plans, 3D representations of particular parts of the site, visualization of tour paths. The establishing of a local museum at the Mycenae is one more challenge for applying phorogrammetric procedures, object modelling techniques with laser scanning, texture mapping, 3D representations, VR applications and Web-related issues. The paper investigates all these possibilities in relation with the data of the particular archaeological site concerning the information supply, the difficulty in demonstrating moveable findings of great value, which are exposed in other museums, and also the knowhow and the financial parameters.

Technological development increases the value of a museum as a means for information dissemination by redefining its features as well as its new relationship with space and people. The creation of virtual reality systems and the development of a worldwide network society offer the museums the ability to promote their exhibits or their education material at a global audience at a relatively low cost. Great help can be offered by the new techniques in 3D geometric recording of objects-monuments of any size and the advanced spatial information management systems. In this paper the basic principles of a new concept regarding the 'space' of the museum is developed. In this concept a museum is examined as a building with its operational characteristics and also according to its information and activity: from the classical serial narration to the creation of different and multiple routes varying from the 'real' to the 'hybrid virtual' space where the real object and...

The use of historical maps in a digital environment can give considerable support to the study of the history of cities. It allows you to combine information from different sources, processed according to different geomatic techniques, to provide a reconstruction of urban configurations of the past and their comparison with iconographic and textual documentation of the same period. The aim of the research is to try to make the knowledge of a historical event easily accessible by converging within a simple model the various sources on which the reconstruction itself is based. This paper deals with the reconstruction of the ephemeral architecture created for Napoleon’s visit to Venice through the generation of 3D virtual models. The reconstruction was approached through a rigorous method, inserting these models into the context for which they were conceived. The generation of the historical city model, taking advantage of the algorithms of structure from motion applied to photogrammet...

Since the Renaissance, the remains, myths and visual representations of ancient Rome have influenced not only European culture but also the architecture and urban planning of the big cities of Europe and of the Americas through the process of colonization. The University of Caen Basse-Normandie (France) has a famous visual representation of ancient Rome in the scale model of Paul Bigot, a French architect who lived at the beginning of the 20th century. This exceptional part of our cultural heritage has been the pretext for a virtual reconstruction of ancient Rome. The technologies used and, in particular, the interactive visit with access to ancient source materials give a new life to the myth. Our team has developed a fully interactive model of ancient Rome which allows a visitor to move freely in a full-scale city and enter the main public buildings as well as some private apartments. The aim is both scientific and didactic. Scholars can use the model as a regularly updated database for reference and possible experiments. The general public can visualize a world that is now beyond their reach. This paper will focus on a particular example ========================================
