Mountain Hamlet Heritage Between Risk and Enhancement
No full textThis paper focuses on villages and hamlets on the mountain considered historical, cultural heritage. Due to their cultural and historical values, they need documentation, enhancement, and revaluation activities. The research aims to semantically and spatially describe minor historical centres such as hamlets affected by natural hazards and risk phenomena (landslide, avalanches, {\ldots}). In this domain, many actors and use cases are involved in different activities such as urban and landscape planning, restoration, tourism, etc. For this reason, it is necessary to develop a replicable and sharable workflow able to harmonise and integrate different sources (spatial, structured, unstructured, historical and so on) to document these centres thoroughly. A significant case study has been selected to apply the presented methodology. It is the hamlet of Pomieri, in the municipality of Prali (Piedmont Region, Alps, Germanasca Valley, Italy). Different documents about natural hazards phenomena have been investigated parallelly to semantic and ontologies sources. This method set the basis for developing a knowledge base, including further information on such centres subject to risk and needing documentation, restoration, preservation, maintenance and planning actions
Un nuovo sistema informativo e collaborativo per i beni archeologici marini della regione Puglia: design, implementazione e scopi
Full text linkI beni archeologici marini – sommersi e costieri - rappresentano una sfida crescente in termini di documentazione, monitoraggio, accesso e conservazione. I recenti progressi tecnologici e la capacità turistica hanno alimentato un crescente interesse verso questo ambito (Bulut & Yüceer, 2023; Manglis et al., 2020; Stefanile, 2016). Tuttavia, la gestione dei dati digitali che documentano questi beni resta complessa (Calantropio & Chiabrando, 2023). Nonostante diverse iniziative nazionali e
internazionali, la documentazione risulta non strutturata, disomogenea e priva di database basati su standard e tesauri condivisi – come ad esempio CIDOC-CRM, Getty CCO e CDWA, UNESCO Thesaurus, e Getty AAT - che consentano la collaborazione e condivisione di dati interoperabili. Esempi come Australian National Shipwrecks Database (AUCHD) e Bermuda 100 Challenge dimostrano il potenziale di una documentazione sistematica per la protezione e promozione dei beni, anche a scopi turistici

Il database spaziale e la sua gestione
Full text linkLa digitalizzazione nel settore delle costruzioni sta offrendo opportunità significative per l’intera filiera delle costruzioni, migliorando le pratiche esistenti, integrando tecnologie e strumenti dirompenti che possono portare a nuovi processi, modelli di business, materiali e soluzioni, con significative potenzialità anche per la gestione del patrimonio architettonico e per le sfide rappresentate dagli obiettivi di riqualificazione del patrimonio esistente. La corretta combinazione di Digitization, Digitalization e Digital trasformation offre l’opportunità di raccogliere le sfide di quest’epoca definendo nuovi metodi e strumenti di lavoro per innovare l’industria delle costruzioni. La digitalizzazione del settore delle costruzioni si concentra su una serie di tematiche legate a tre categorie principali: i) tecnologie di acquisizione dei dati (e.g. sensori); ii) processi di automazione (e.g. robotica); informazioni e analisi digitali (e.g. Building Information Modelling - BIM) per la rappresentazione grafica
Reanalysis-based mesoscale wind maps for the design of structures and infrastructures with an application to Italy
Full text linkSynoptic extreme winds are traditionally mapped at the lower bound of the countrywide macroscale resolution (hundreds of km) on the basis of time series measured at land anemometric stations, while the assessment of the design wind speed at the construction site is entrusted to the designer within the so-called return criterion. Coarse, uneven distribution of the stations, uncertainties in their setup, measurement errors, challenging subjective evaluation of the exposure roughness, inconsistencies among national wind provisions are some of the critical issues affecting the in force map-and-return approach. This study is intended to test an alternative approach to directly assess the wind hazard at the lower bound of the meso-y scale resolution (about 2 km) around a construction site. The approach is grounded on data issued from a weather forecast computational model, its reanalysis by means of assimilated remote sensing observations, and possibly its downscaling. Three different reanalysis/downscaling models are adopted. The resulting wind maps over the Italian Country are critically compared with measurements at 21 stations. The errors made by each model are assessed for current and extreme wind speed with different return periods. Finally, a reanalysis-based engineering approach to design wind speed is presented by proposing model correction factors
Addressing Flood Risk Assessment and Heritage Conservation by Integrating HBIM and GIS: The Case Study of Castello del Valentino (Italy)
Full text linkClimate change and increasingly frequent extreme weather events pose critical threats to cultural heritage, particularly flood-prone historic sites. This study presents an integrated workflow combining Historic Building Information Modelling (HBIM) and Geographic Information Systems (GIS) for flood risk assessment and heritage conservation. The methodology is applied to the Valentino Castle in Turin, a UNESCO-listed site located along the Po River, vulnerable to recurrent flood events. A semantically rich HBIM model was developed from high-resolution point cloud data to document the architectural and material characteristics of the castle. This model was then integrated into a multi-scale 3D GIS environment to simulate various flood scenarios and assess their impact on building elements. The workflow addresses technical challenges such as BIM-GIS interoperability, semantic-geometric translation, and applying Level of Information Need (LOIN) in heritage contexts. The resulting framework allows for detailed, spatially accurate vulnerability assessments and supports decision-making for risk mitigation, preservation planning, and stakeholder communication. While Valentino Castle is the case study for this first methodological validation, the proposed method is scalable and adaptable to other heritage sites. Integrating HBIM and GIS proves to be a valuable tool for protecting cultural assets in the face of climate-induced hazards
A Geodatabase Design for the Development of a Digital Twin for Urban Environments: A Case Study from Turin, Italy
Full text link3D City models are essential for urban planning, accurately visualizing, analyzing, and simulating urban environments. They find applications in various fields like AEC (Architecture and Construction), urban and transportation planning, development and conservation processes, energy systems monitoring, and many more. Extensive datasets for the 3D City Models need to be organized following international standards to make them reusable and sharable for different stakeholders. Designing a Geodatabase (GeoDB) for a 3D city model is crucial for data management as it is helpful in the streamlined visualization and analysis of the city's features and relations among its objects. Over the years, 3D city models have evolved into Urban Digital Twins, offering dynamic real-time simulations of cities and even better management and analysis of urban processes. This transition from 3D city models to UDTs enhances decision-making by providing detailed insights into the dynamics of urban systems, enabling better urban management and planning. This research concentrates on building a GeoDB to support the UDT. The paper discusses the data acquisition, processing, and integration methodologies.
Additionally, it highlights the significance of utilizing advanced remote sensing technologies such as aerial LiDAR and aerial photogrammetry to enhance the digital twin’s quality and richness in detail. The semantics of the built environment datasets are clarified and strictly defined for the most important UDT features, such as buildings, roads, trees, and other features. This will ensure everyone can interpret the data similarly, leading to better analysis and decision-making
A Review of Existing Sources for the Design of an Archaeological Underwater Cultural Heritage Database of Puglia Region (Italy)
Full text linkUnderwater cultural heritage (UCH) in Italy is under-documented despite its significance. Creating a comprehensive UCH database is essential but faces challenges, such as complex documentation processes, data interoperability, and international standard adherence. This paper examines data models, standards, and the use of webGIS and databases for underwater cultural heritage documentation in Italy and globally. International documents like the 1996 ICOMOS Charter and the 2001 UNESCO Convention emphasize in-situ preservation. However, documentation efforts remain scattered, lacking a unified database. GIS technologies are vital for managing and analyzing UCH data but are underutilized for public access and tourism. Projects like Andar per Mare and Archim3des in the Puglia region aim to promote underwater cultural heritage using webGIS platforms. However, existing sources like CartaPulia face limitations, including a lack of standardization, specialized fields for underwater cultural heritage characteristics, and language barriers. The proposed solution involves creating a new data model based on standards, resulting in a bilingual geodatabase. This geodatabase will support scientific and tourism-focused webGIS applications, enhancing accessibility and promoting Italy's underwater cultural heritage. A unified database will prevent duplication, facilitate discoveries, and promote Italy's cultural heritage

Full text linkA Framework Research: Investigating Different Methods and Solutions to Map Built Heritage at Risk Through Participatory and Crowd Actions
No full textThe conservation of built heritage is a critical issue, concerning the
evolving urban landscapes, potential threats to historical heritage, and the different
stresses that expose heritage to risk. The present paper focuses on the upcoming
theme of perceived risk, exploring the suitable and fundamental role of specific
and promising participatory representation tools, such as community maps,
crowd mapping, and video mapping, in empowering communities and facilitating
informed decision-making processes toward risk management and mitigation.
This contribution underlines the existing challenge of implementing and integrating
scientific knowledge with local and perceived knowledge about risk exposure.
Therefore, the above-mentioned participative tools are discussed, compared,
and proposed as methods to fill the gap between the recognized and perceived risk,
underlying their usefulness and contribution to risk evaluation within a comprehensive
framework, including the dimension of the perceived risk. These methodologies
are designed to serve citizens as users of the surrounding space and the primary
individuals expressing individual perceptions of risk. They also cater to expert
technicians responsible for implementing these methodologies. Lastly, they aim
to support policymakers or decision-makers in making decisions ideally informed
by these experiences and the results achieved applying these methodologies
