The location of the slided area and the exact date of the event were not known in advance. A post-processing strategy was applied on the displacement time series in order to aid the detection of instability signs and to enable the identification of the location and the narrowing down of the time interval of the slide. InSAR displacement time series were obtained following the small baseline subset approach implemented on an automatic processing platform. Distributed scatterers were clustered based on the similarity of their displacement time series, in order to form clusters of scatterers with similar behavior. This procedure allowed the computation of displacement time series representative of each cluster, aiding the detection of instability signs on the slope. One of the clusters showed a sudden movement away from the SAR sensor. It was later confirmed that the slide had occurred at the location of the scatterers belonging to that cluster and during the time interval between the two observation epochs corresponding to the break in the time series. In conclusion, the proposed method was effective in the back-analysis of the slope failure, hopefully contributing to the uptake of InSAR technology by structural safety experts.

Este analisis se centra en la region portuguesa del Bajo Alentejo, donde se han destruido multiples sitios en los ultimos anos debido a la agricultura intensiva. El desarrollo de un sistema de vigilancia basado en datos de las constelaciones de satelites Sentinel 1 y Sentinel 2, SENSEOS, tuvo su aplicacion piloto en esta region durante el primer semestre de 2019. En una region donde las autoridades carecian de los recursos adecuados para detectar eventos a tiempo, poniendo en peligro la integridad de los sitios, este sistema intento superar estos problemas. El uso de radar de apertura sintetica (SAR) y datos opticos permitio detectar eventos a traves de una tecnica denominada Indice de Diferencia Normalizada de Amplitud (NDAI), identificando cambios en la superficie asociados con eventos destructivos y minimizando la destruccion de los sitios arqueologicos.

This analysis focuses on the Portuguese Lower Alentejo region, where multiple sites have been destroyed over the last years, mainly due to intensive agriculture. The development of a surveillance system based on data from the Sentinel 1 and Sentinel 2 satellite constellations, named SENSEOS, had its pilot application in this region during the first half of 2019. In a vast region where authorities lacked the proper resources to timely detect events endangering the integrity of heritage sites, this system tried to overcome these issues.

Com efeito, não se entende a maratona como meta de um trabalho de valorização patrimonial, mas como uma ferramenta de capacitação de um sítio arqueológico de uma compreensão mais alargada e mais democrática. Procura-se a simplicidade na maneira de transmitir os conteúdos científicos que proporciona cada disciplina, permitindo depois desenvolver conteúdo interativo capaz de mostrar arquiteturas e vivências da antiguidade, sem perder as referências fundamentais que a arqueologia exige na atualidade.

Moreover to examine the qualitative and emotional factors often essential in order to communicate facts deriving from a scientific research. We have welcomed recent projects that made use of CGI techniques in order to communicate to the public the constructed stories, after an archaeological research has been pursued. The final purpose of this session was therefore to open a discussion on the current situation of digital CGI visuali-zation in Cultural Heritage and archaeological practice. The intention was to put together investigators with different background experience in order to approach the issue at various levels and with different perspectives. This has been achieved by inviting to present the work of researchers involved in the study, the construction and the divulgation of different cultural heritage contents. The themes discussed were both theoretical and real project examples, this is because it was necessary to maintain not only a vivid discussion on the principle of past and modern visualization techniques but also on the new accurate surveys and digital reconstruction methodologies that make these final outputs more appreciable by the general public.

No decorrer das sucessivas campanhas de escavação ocorridas desde então, foi possível recons<tuir grande parte da planta desta importante infraestrutura pública de Al-'Ulyà. Conseguiu-se perceber que era cons<tuído por um vesRbulo que daria acesso a três salas paralelas (sala fria, tépida e quente), exis<ndo um hipocausto sob estas duas úl<mas. Os banhos seguramente um elemento central nas dinâmicas sociais quo<dianas da cidade, à semelhança do que ocorre no resto do mundo islâmico medieval .

virtual reality systems and 3D printing, have been pushing boundaries in the ways that archaeological fieldwork,
research and dissemination are being conducted.
The application of these digital technologies has opened a wide range of possibilities and solutions in the preservation
and dissemination of archaeological and cultural heritage, playing an especially important role in unstable socio-political
contexts. The sites of Tell Beydar (Syria) and Kani Shaie (Iraqi Kurdistan) were thus chosen as case-studies where modern
approaches to archaeological heritage have been developed.

The massive deposition of objects (mainly pottery) on a slope of the Cerro do Castelo (a small hill in the center of Garvão) had an intentional nature and has been associated to ritual practices. Despite the undeniable importance of the findings, it has been a challenge so far to satisfactorily exhibit this vast archaeological collection. The development of innovative digital tools emerged as a possible solution to overcome this problem.
One of the main aspects of this work was the creation of a Virtual Museum, in articulation with a physical exhibition installed in Ourique. The digitisation of artifacts for the Virtual Museum was carried out using two different approaches: photogrammetic survey and 3D laser scanning. Aerial photogrammetic surveys were also performed to generate a Digital Terrain Model (DTM) of the Cerro do Castelo (Garvão, Ourique). 3D technology was also incorporated in the physical exhibition itself, with the use of Augmented Reality tools, Immersive Virtual Reality and the 3D printing of replicas.
