# The IoT/IoE Integrated Security & Safety System of Pompeii Archeological Park
## 15 The Informative Systems
These images then undergo sophisticated post-processing techniques--including photogrammetry, 3D reconstruction, and automated image analysis--to detect even subtle signs of deterioration, deformation, or damage not easily visible during ground inspections. In addition, diagnostic investigations conducted using techniques such as ground-penetrating radar, infrared thermography, and laser scanning provide critical data about subsurface structures and material conditions. The re-processing of these diagnostic data support the creation of detailed risk maps, highlighting vulnerable zones, structural weaknesses, and areas with high exposure to environmental threats such as humidity, erosion, or seismic activity. All these activities are part of a broader strategy aimed at identifying and classifying potential risks to the protected archeological assets. This includes not only the physical vulnerability of the artifacts and structures themselves but also their contextual exposure--such as visitor flow, environmental conditions, and proximity to infrastructure. Understanding these risk factors is essential to developing effective, evidence-based conservation and maintenance strategies. The proposed model for this risk assessment and management process is structured in five sequential stages. The first stage, Knowledge, represents the foundational understanding of the site, much of which has already been established through the previous Great Pompeii Project that began in 2013. This includes detailed documentation, historical research, and baseline condition assessments of the site's structures and features. The second stage involves Expeditious Inspections, which refers to systematic surveys of all archeological assets using a comprehensive, site-wide approach. These inspections are designed to be repeated on a semi-annual or annual basis and feed into a centralized damage/defect/criticality database, which forms part of the broader Smart@Pompeii project. The structured and periodic nature of these inspections ensures that the site is regularly monitored and that emerging issues can be addressed promptly. In the third stage, the focus shifts to the Identification of Potential Risk Classes. Here, different areas, structures, and elements within the site are categorized based on their level of risk, taking into account both their physical condition and their contextual exposure. This classification serves as a critical input for prioritizing interventions and allocating resources efficiently. The fourth stage emphasizes the Monitoring of the Riskiest Situations, where targeted observation and data collection will be intensified in the areas most susceptible to damage or degradation. This monitoring is expected to be continuous or periodic depending on the severity of the risk and will rely heavily on the technological infrastructure developed under the informative system. The final stage involves In-Depth Analysis of Specific Situations, where complex or ambiguous cases are examined in greater detail. These analyses will provide essential information to inform the long-term maintenance management plan, ensuring that conservation efforts are both proactive and sustainable. Ultimately, the results of all these activities and analyses are integrated into the park's Web-GIS information system. This centralized geospatial platform will allow authorized users to visualize, analyze, and manage spatial data related to the condition and maintenance of the archeological assets. Additionally, the inspection activities are interconnected with the instant messaging system, which enhances coordination among staff, enables real-time communication during fieldwork, and streamlines the overall workflow of site monitoring and management.
