“…Prior to this study, many scholars have explored and studied the monitoring of formations in heritage building communities, some of which mainly use traditional formation monitoring methods, such as full stationers, GPS, InSAR, and so on. For example, the authors of reference [8] achieved a better effect with the use of the full-stage monitoring of an ancient building; and reference [9] uses InSAR technology to monitor the massive heritage building communities, and obtains more accurate information about the transformation. However, these approaches have problems with monitoring accuracy that are greatly influenced by environmental conditions and human factors, and require a lot of human and material resources, making large-scale remote sensing monitoring difficult.…”

The protection of heritage building communities is of important historical significance, the occurrence of a landslide is related to the safety and stability of the heritage building, and ground monitoring and forecasting are the key steps for the early warning and timely restoration of the heritage building. This study utilizes remote sensing technology to monitor the ground of a cultural heritage building, and employs a Long Short-Term Memory (LSTM) network for prediction. Firstly, we conducted ground subsidence monitoring within a specific time series of the study area using heritage remote sensing images and SBAS-InSAR technology. Following the subsidence monitoring, and incorporating an attention mechanism, we effectively localized and extracted features of heritage building clusters within the region. This approach efficiently addresses the challenge of feature identification resulting from the dense distribution of buildings and the similarity between various objects. The results indicate that the maximum subsidence rate in the research area reached −60 mm/year, reached a maximum uplift rate of 45 mm/year, and that the maximum cumulative subsidence reached −65 mm. Secondly, for the multi-level, multi-scale, and class-specific objects in remote sensing images, the LSTM network enables adaptive contextual information during deep and shallow feature extraction. This allows for better contextual modeling and the correlation between predicted and actual results reaches a 0.95 correlation, demonstrating the accurate predictive performance of the LSTM network. In conclusion, both LSTM and SBAS technologies play a crucial role in decision-making for heritage buildings, facilitating effective early warning and disaster mitigation.

“…Reduced configurations to study accessibility can also determine further variability to the final measurements, from the point of view of the number of points considered in the calculations, compared to the reference configuration, which includes all the monitoring points [35].…”

“…These aim at tracing the escaping tracks and maps and/or checking the available areas for safe evacuation of people. In a previous application [19] the authors faced the above problem with reference to the definition of an evacuation plan of a baroque cathedral located in Italy, which is characterized by having a complex structure and where hundreds of people could be present at the same time. To this purpose, a preliminary mapping of the monument has been carried out by using a terrestrial laser scanning to obtain the cloud points.…”

The design of evacuation plans for safety purposes is based on the graphical synthesis and visualization of data derived from high-performance measurement systems. The data post-processing requires some suitable procedures including many steps, to obtain the information needed. These are related to the global use of the measurement system, to the real measurement operating conditions, to the complexity of the building, to the simplifying hypotheses, to the data management. As a preliminary step, this work outlines a procedure for extracting a floor plan from a points cloud acquired by means of a laser scanner. The test case is a baroque cathedral, being a large structure and presenting some elements of irregular geometry. Some critical passages have been examined, presenting similar widths but different characteristics i.e., flat and regular geometries of the elements on the walls, in some cases, statues, columns and adornments, in some others. The data management plays a key-role in the correct interpretation of the outcomes, having a great impact on the results reliability. The obtained estimated variability of the passage width is in the order of few tenth centimeters. This is strictly related to the specific operating procedure. How this affects simulation software for route optimization of emergency paths will be the object of further investigations.
