“…UAV offer timely, very accurate and with low cost 3D data like orthophotos, Digital Surface Models (DSMs), and 3D point clouds. Several recent studies have also demonstrated the power of UAV data in combination with Structure from Motion algorithms for rockfall 8,9 , or landslide 10,11,12,13,14,15 mapping and monitoring. In a very recent study, a guideline for researchers who try to follow the UAV photogrammetric survey method for landslide mapping and monitoring was presented 10 .…”

The preservation of cultural heritage and landscapes, which are constantly endangered by man-made hazards and natural disasters (earthquakes, landslides, floods, fires, urbanization, etc.) is a strategic priority for humanity. Nowadays, remote sensing stands out as an important, innovative and cost-effective tool with great potentialities for the protection and monitoring of cultural heritage as well as the prevention of monuments and sites, due to non-invasiveness in such a vulnerable research objective. In this context, remote sensing data, acquired by Unmanned Aerial Vehicles (UAV) and Terrestrial Laser Scanning (TLS) surveys were utilized for the precise mapping and monitoring of rockfalls occurred over an eleventh-century BC. Holy Monastery. The monastery is built on a rocky slope, which hangs over the bank of the ancient river Triton, and it is located a few kilometers away of the village of Andritsena within the Region of Western Greece. Significant damages to the dome of the monastery were detected after the occurrence of rockfalls in late January 2021. Remote sensing data were collected over the monastery area and were processed appropriately. UAV and TLS point cloud were generated and change detection methods were applied for the precise mapping of the rockfalls. Moreover, UAV and TLS point clouds were integrated towards a more comprehensive mapping.

A Buddhist monastery revealed by UAV survey and ground-penetrating radar in eastern Mongolia

Abstract: The site of the Dzuun Khuree monastery in the Upper Kherlen Valley of eastern Mongolia was recently investigated by UAV and ground-penetrating radar. The monastery's highly unusual circular form and layout suggest a foundation earlier than previously suspected.
