Abstract
The structural analysis of cultural heritage buildings, including their monitoring and maintenance, requires accurate 3D models of the structure, especially when these monuments are threatened (e.g., anthropogenic and natural disturbances). However, monuments such as castles and monasteries often lack such construction plans. Structure from motion (SfM) photogrammetry and Terrestrial Laser Scanning (TLS) techniques can provide a geometrically accurate and cost-efficient survey solution to derive such plans. The accuracy and spatial resolution of the derived 3D reconstructions depend on instrumentation and data processing procedures. Here, remote sensing data, acquired from Unmanned Aerial Vehicles (UAV) and TLS surveys, were combined to map and monitor an eighteenth-century monastery. The monastery, located close to the village of Skoutera in Western Greece, is within the area of an active landslide that has already impacted different building elements. Significant cracks have appeared on the ground floor and the walls of the building putting its structural integrity in question. A DJI Phantom four Pro UAV together with photogrammetry were used for the aerial surveys. Ground observations with a Leica P50 TLS were used to map the interior and the exterior of the monastery. The derived 3D point clouds from the TLS scans obtained at different time periods were processed with change detection methods for the precise mapping of the ongoing displacements in building’s elements and quantitative mapping of the cracks. Moreover, a Building Information Modeling (BIM) approach was used to generate a structural plan of the monastery that could facilitate the monitoring process and possible maintenance interventions in the future.
