Non-destructive system for in-wall moisture assessment of cultural heritage buildings

• Non-destructive system for in-wall moisture assessment of cultural heritage buildings. Geo-positioning microwave monitoring. Cultural preservation and safeguarding. In-depth wall measurement location the content. sites are exposed to several factors that cause their deterioration degradation, namely There destructive non-destructive methods available monitor moisture. However, avoided in prevent surface damage, while limited penetration capabilities. This study proposed geo-positioning based on spectroscopy close-range photogrammetry. The experimental data were collected at Museum King Jan III's Palace Wilanów, Poland. was analysed using clustering algorithms ( t -SNE, PCA, K-Means Hierarchical), which demonstrated clear clusters. results did not fully align with pin-type as able penetrate through material, whereas meter only measured surface. Therefore, sensing approach provided more detailed information material.
