Abstract. Cultural heritage represents the link between past and present civilizations, contributing to the right appreciation of the present-day by understanding the historical evolution of different human communities that are shaping our world. Preservation of the cultural heritage and mitigating potential risks on invaluable artifacts or objectives is key to conserving the identity of present and future generations. Our complex project is dedicated to monitoring, conservation, protection and promotion of the Romanian cultural heritage. It addresses the challenge of better safeguarding the cultural heritage by developing a multidisciplinary approach.The combined use of Synthetic Aperture Radar and multispectral satellite imagery represent a non-invasive investigation instrument that enable multitemporal analysis, contributing with valuable insights regarding cultural heritage sites. Remote sensing techniques were used to generate geospatial products such as displacement maps, urban sprawl evolution maps, urban heat island maps and many more.For protecting important artifacts, innovative recipes based on nanotechnologies were developed. In order to promote these artifacts, 3D photorealistic models were created using 3D reconstruction technology. For selected cultural heritage objectives, an integrated LiDAR aerial mapping system has enabled the creation of a high accuracy 3D model.This paper illustrates how different technologies, ranging from remote sensing to nanotechnology, could be used for safeguarding and promoting the Romanian cultural heritage and represents a first step in establishing and consolidating a multidisciplinary team involved in this domain.

Abstract. The promotion and dissemination of architectural heritage for cultural enhancement and touristic enjoyment are increasingly focused on innovative ICTs, including 3D Geographic Information Systems, photorealistic models and scenes, and VR/AR immersive digital environments, which enable the interaction of visitors with a variety of informational contents, both educational and specialist. Within the above-mentioned framework, this paper will firstly outline the general objectives of the project “3D-IMP-ACT”, which has been funded under the international cooperation programme IPA CBC Interreg Italy-Albania-Montenegro. In this research, some ICT tools are tested and validated to create “virtual networks” of international ancient architectures and sites, based on the identification of “physical networks” of common historic, environmental and technical characteristics and infrastructural connections, in order to address coordinated strategies and transversal policies for development and management. Then, the paper will describe and discuss some results from the design and implementation of the project WebGIS system, which integrates virtual tours of 360° panoramas, 3D models from photomodelling of pictures taken by drones, multimedia contents, and 2D/3D historic evolution schemes within a single platform, where the users are supported in recognizing and exploring the tangible and intangible correspondences among the project pilot-cases. In conclusion, some remarks will be proposed on the potential benefits of the platform as an expert system which supports the technical assessment and control of architectural heritage toward maintenance, refurbishment and conservation.

Abstract In material cultural heritage documentation, the use of measurement methods, i.e. photogrammetry and laser scanning, is becoming more and more common. The increasing availability of hardware and software allows to create the photorealistic models of objects documenting the heritage and the state of its preservation. The virtual object model can carry information about the dimensions, shape, color and texture of the documented object and it can be the basis for the documentation of the archaeological site, architectural and construction inventory, architectural and conservation studies and monitoring the condition of the object. In the paper presented an overview of the most important measurement techniques and methods for acquiring spatial data used in the documentation of monuments, with particular reference to photogrammetric documentation generated on the basis of data obtained from photographs made with the use of UAV. The heritage documentation presented in the paper were created using the Agisoft Photoscan software. The use of geographic information systems in storing, analyzing and sharing information about monuments was also discussed.

Purpose Representative cultural heritage sites and monuments around the world have been lost or damaged by natural disasters, human conflicts and daily erosion and deterioration. Documentation and digital preservation by using three-dimensional (3D) modeling techniques enables to ensure the knowledge and access for future generations. Efficient working methods and techniques should be proposed for this purpose. Design/methodology/approach In this paper, a methodology for the generation of 3D photorealistic models of representative historical buildings is introduced, for using data are obtained using terrestrial laser scanning systems and photogrammetry. Findings In this paper, an approach to reconstruct 3D photorealistic models by using laser scanning and photogrammetric data is shown. Combination of data from both sources offers an improved solution for 3D reconstruction of historical buildings, sites and places. Integration of 3D models into virtual globes and/or software applications can ensure digital preservation and knowledge for next generations. Research limitations/implications Results obtained in a concrete building are shown. However, each building or studied area can show some other different drawbacks. Practical implications The study enables to generate 3D and four-dimensional models of most valuable buildings and contribute to the preservation and documentation of the cultural heritage. Social implications The study enables digital documentation and preservation of cultural heritage. Originality/value A proper solution at field (in a real and complicated case) is explained, in addition to the results, which are shown.

This paper presents a study of the process of virtualization or a cultural heritage modeling of Joglo house, an old Javanese house, through observation method. The method consists of three aspects as the following: (1) to observations and measurements, (2) to create a virtual image of the cultural heritage and (3) to integrate the all component of the cultural heritage house, so that the final image is expected to be the replicate of the original house. Additionally, in the process of making traditional Joglo house model, there is another aspect that has been conducted, it was to create harmony between the display of a merger of two and three-dimensional photorealistic models which was made with the help of computer-based applications, namely Computer Aided Design (CAD). As such, by implementing these methods, the reconstruction of cultural heritage of the Joglo house, the Kartasura, can be realized.

<p>Metric and graphic documentation of archaeological cultural heritage requires effective solutions for archiving, visualization, analysis, management, and monitoring of different monuments and sites. This paper presents the geomatic workflow undertaken on a singular rock art site, Coves de la Saltadora. The cave is part of the Rock Art of the Mediterranean Basin on the Iberian Peninsula declared World Heritage Site by UNESCO in1998. The different steps are reviewed, starting from the data acquisition until the final delivery of part of the metric outputs such as 3D models, photorealistic models, orthophoto mosaics in two levels, general and detail.</p>
