The paper presents the results of fieldwork and geodetic surveys carried out on a landslide in Wleń (Western Sudetes, Izerskie Foothills). This reactivated landslide occured firstly in 2011 and later on 16th July 2016, following heavy rainfall in the Lower Silesia region, and covered an area of ca. 1100 m2 above the renovated “Leśny Dwór” guesthouse in Wleń town. The main scarp of the landslide is built of strongly deformed Upper Permian (Zechstein) heterolithic deposits, composing the marginal part of the Wleń Graben - a NW-SE elongated, tectonic sub-unit within the North Sudetic Synclinorium. The landslide was a consequence of undercutting of steep slopes of the Bóbr River valley by anthropogenic activities and loading of the slope surface by blocks and pedestrian paths in the vicinity of the guesthouse. Monitoring of landslide activity was performed using the initial surface model of the slope subjected to mass movements, LiDAR elevation data, as well as 3D point cloud data from a non-metric camera on an Unmanned Aerial Vehicle (UAV). They were used to construct digital elevation models (DEMs) of the area covered by the landslide. The DEM from photogrammetric UAV data was processed using Structure from Motion (SfM) technology. The obtained dataset was verified by additional measurement series from terrestrial laser scanning (TLS). and Kowalski Aleksander, Wajs Jaroslaw, Kasza Damian.
Technical marks as a neglected archaeological record? Photogrammetric analysis of the bottoms of vessels from Great Moravian pottery workshops at the 'U Víta' site in Staré Město (Uherské Hradiště district).
Práce prezentuje možné alternativy v přístupu k vyhodnocování souborů keramických nádob se značkami na dnech. Prostřednictvím analýzy ukázkového souboru ze dvou předpokládaných hrnčířských dílen ze Starého Města (okr. Uherské Hradiště), polohy „U Víta“ jsou ilustrovány přednosti metody fotogrammetrické dokumentace a následného porovnávání záznamů ve virtuálním prostředí. Možnosti virtuálního porovnání archeologického materiálu jsou testovány nejen na tradičně vyhodnocovaných značkách s reliéfními symboly (tzv. značky plastické), ale i na dosud opomíjených otiscích os na dnech nádob (značky technické) a také některých dalších neintencionálních otiscích. Prostřednictvím obdržených výsledků se pak práce zamýšlí i nad možnou úrovní organizace produkce v obou pojednávaných dílnách. and The work presents possible alternatives in approaching the evaluation of assemblages of pottery vessels with marks on their bottoms. By means of an analysis of a sample group from two assumed pottery workshops from the ‘U Víta’ site in Staré Město (Uherské Hradiště district), the benefits of the method of photogrammetric documentation are illustrated and records from the virtual environment are subsequently compared. The possibilities for the virtual comparison of archaeological material are tested not only on traditionally evaluated marks with relief symbols, but also on heretofore neglected axis imprints (technical marks) as well as some other additional unintentional imprints. Based in the obtained results, the work then considers the possible level of production organisation at both of the studied workshops.
