Abstract
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.
Highlights
The promotion and dissemination of historical-architectural sites and buildings for cultural enhancement and touristic enjoyment are nowadays increasingly focused on innovative enabling Information and Communication Technologies (ICT) for the restitution of so-called Digital Heritage (DH).In particular, the most common acquisition techniques, from topography to laser scanning, and from terrestrial to aerial digital photogrammetry, including by Unmanned Aerial Vehicles (UAVs), has the potential to address a variety of 3D representation solutions, e.g. 360° panoramic scenes, coloured point clouds and texturized polygonal meshes, as well as geometry modelling and surface rendering by Computer Assisted Design (CAD) tools

These solutions might be visualized by different systems, such as Geographical Information Systems (GIS), virtual tours, virtual reality (VR) environments and augmented reality (AR) contents
Summary
The most common acquisition techniques, from topography to laser scanning, and from terrestrial to aerial digital photogrammetry, including by Unmanned Aerial Vehicles (UAVs), has the potential to address a variety of 3D representation solutions, e.g. 360° panoramic scenes, coloured point clouds and texturized polygonal meshes, as well as geometry modelling and surface rendering by Computer Assisted Design (CAD) tools These solutions might be visualized by different systems, such as Geographical Information Systems (GIS), virtual tours, virtual reality (VR) environments and augmented reality (AR) contents. Within the prolific and dynamic scientific literature on the abovementioned topics, the most interesting field for the present study, in the light of its recent evolution, concerns the research and applications of photoscanning-based digital models and environments that are integrated in platforms for data storage, consultation and management, within geographic reference systems Such integration and application are able to address two correlated and complementary requirements for cultural enhancement and touristic enjoyment.
