This article seeks to highlight the vanished and not-so-well-known material culture of historical southern Moroccan Jewry. Jewish settlements could be found practically in the whole of North Africa before the Second World War; however, afterwards, it almost completely disappeared due to the political changes in the region and the establishment of the state of Israel. In southern Morocco, the last Jewish communities were present until the 1950s. Thanks to the interest of the Moroccan authorities, an effort has been made to restore some monuments and keep them as part of the cultural heritage that has attracted foreign tourists for the last few years. As part of the expeditionary research of Charles University and the Czech Technical University in Prague, several documentation projects were carried out in 2020, some of the results of which are described in this paper. Modern automatic methods of geomatics, such as easy to use laser scanning, mobile laser scanning in PLS modification (personal laser scanning), and close-range photogrammetry were used. The results of documentation were processed in the form of 3D models and basic plans, which are used mainly for analyzing residential zones of the Jewish population, the so-called mellahs. In this article, two case projects are described. In both cases, all the mentioned documentation methods were used. The technologies used were analyzed in terms of data collection speed, price, transport, and possible difficulties in use. The PLS technology is relatively new and still under development, such as miniaturising of other measuring instruments. Accuracy testing and usability of above-mentioned technology in cultural heritage documentation real practice is the benefit of this research. Finally, a second aim was to provide information of abandoned cultural places and constructions, which are on the edge of interest and endangered by destruction. It clearly shows that PLS technology is very fast and suitable for these types of objects.

“…Durante esta última década, el escáner láser terrestre (Terrestrial Laser Scanning, TLS) ha sido la principal herramienta para la obtención de datos 3D de objetos patrimoniales complejos (Alshawabkeh, El-Khalili, Almasri, Bala'awi, & Al-Massarweh, 2020). Presenta la ventaja de la medición masiva de datos en un corto período de tiempo.…”

One of the main objectives of heritage management policies is to promote measures aimed at the maintenance, restoration and enhancement of cultural and archaeological assets. To guarantee this, the responsible institutions must promote actions for the dissemination and transference of cultural heritage, as well as promoting actions with the greatest possible rigour, developing scientific and technical studies that support and improve intervention methods. Recent technological advances in fields such as photogrammetry, digital terrestrial scanning and 3D modelling have made a significant contribution to the digital preservation and dissemination of architectural heritage.European administrations, in their desire of regional development, as well as the central or local governments have notably boosted the recovery of their rich and diverse heritage. A particular case is Priego de Cordoba’s Castle, a stronghold which was one of the most important monumental icons of the Andalusian period.Currently, this site is the main target of many architectural interventions and a model due to the implementation of last generation techniques in digital preservation. The local archaeological department promotes a large number of interventions and archaeological excavations. This has made a priority to get a qualitative geometrical 3D documentation, and therefore a constantly updated the point cloud (xyzRGB).This paper is focussed on presenting the results of the digital preservation process through 2D planimetry obtained from photogrammetric technics, 3D models, and geospatial data. These techniques are a previous step to large architectonical intervention planned in Priego de Cordoba’s Castle, in particular, the identified structures as Wall 1 and Tower 1.Two out of the three studied structures can be found in Wall 1. They correspond to a cobblestone pavement located in the rampart of the Wall 1, which is a post-medieval period; a double-stepped semi-underground path, excavated in the infill of the wall. The third structure studied in this paper consists of a well, which drills vertically the infill of the wall of the Tower 1. This feature is interpreted in the last research as a vertical well to place the weights of the clock sited in this tower until the 19th century.This work combines two techniques of geometric documentation to obtain a more complete point cloud. The terrestrial laser scanning, and the photogrammetry due to the higher colour performance, along with the completion of the point cloud obtained with the laser scanner. Along with this study, we will analyse the features which will better define the best technique to fit the documentation of the different structures. Their geometric characteristics, the incidence of sunlight or the accessibility will condition the use and choice of the technique.We have stated that there is software nowadays which makes it easier to access and consult the information through new computing hardware. Besides, we have highlighted the importance of knowledge and synergy from the different stakeholders implied (city council, technological centre and private companies). The final goal consists of making the society aware of the capital importance of digital preservation as well as dissemination of science.

“…Digitization is very important in the process of evaluation-preservation-restoration of the elements that make up the cultural heritage, and can also have attributions in the dissemination of knowledge. In the eld of research related to cultural heritage and geohazards, with the advancement of digital technology, new methods are identi ed in order to conserve heritage assets, photogrammetry and 3D scanning (Alshawabkeh et al 2020). By the three-dimensional models resulted, one can map, compare and study aspects of cultural heritage; these possibilities making them ideal for conservation and restoration (Scopigno et al 2011; Akoglu et al 2019).…”

The impact that geohazards have on cultural heritage requires continuous research in order to assess risks, prevention and conservation. This study has as the main research object, a uniquen monument in terms of its connection with the risk phenomena. It is about a wooden church historical monument from the village of Corbești, Romania, which was destroyed at the beginning of the tenth decade of the last century by a meteorological hazard, later reconstructed on a new site (in Oradea Municipality), and currently there is a risk of being affected by a geological hazard. The study focused on three main directions of research, namely: reconstructing the film of events, analyzing current risks and finding viable methods for future conservation and promotion. The methodology is based on extensive field research and the use of digital technologies. The results obtained confirmed the church's tendency to be affected by the emergence of a new risk phenomenon - landslides. In order to conserve and rebuild in case of need, the monument was digitized and a three-dimensional model of high accuracy was developed. This approach has the advantage of being low-cost, fast, non-invasive and providing large volumes of valuable information in the process of cultural heritage conservation.
