“…The critical issue previously evidenced requires a number of different geomatics methodologies to be employed in the project that are: Survey techniques useful to acquire 3D data at different scales of investigation (ranging from the single building to the district). Satellite and aerial photogrammetry, including UAV are being used to obtain DEMs [ 17 , 18 ]. A slightly different approach, included in an open source tool for DEMs generation from high resolution optical satellite imagery, will also be considered [ 19 ].…”

The presented paper describes the ReSCUDE project, developed by the Department of Civil, Environmental, Land, Construction and Chemistry (DICATECh) of the Polytechnic University of Bari under the grant Attraction and International Mobility, of the Italian Ministry of Education, University and Research. The project focuses on the evaluation of the effects of Slow-Onset Disasters (SODs), and Rapid Onset Disasters (RODs) on historic town centres. To this end, an integrated approach based on innovative geomatics, building techniques and advanced behavioural models, is being applied to the old town built area of Ascoli Satriano (FG) and Molfetta (BA) in the Apulia Region (Italy). Over the next three years, the ResCUDE project will allow to perform in-depth analyses on the historic built environment of the identified case studies, fostering the processes of its knowledge, assessment, control, management and design, in connection to the risks deriving from ROD and SOD events. The expected outputs will be useful to define possible scenarios for civil defence purposes and undertake actions aimed at risk mitigation.

“…The "Pozzo del Merro" sinkhole is located at 140 m a.s.l., on the southern slopes of Cornicolani Mountains (site La Selva 42 • 02 ′ 21 ′′ N, 12 • 40 ′ 50 ′′ E, Sant'Angelo Romano, Latium, central Italy [10]), and is within the "Macchia di Gattaceca e Macchia del Barco" nature reserve (997 hectares; Cornicolani Mountains). It is a funnel-shaped cenote (cavecollapse sinkholes), with a diameter of about 200 m at ground level (7 ha), narrowing to 25 m at the lake water surface 80 m below (Figure 1).…”

Karstic sinkholes are peculiar structures hosting specific biological communities. Birds are still little studied in this regard. This note reports, for the first time, original data relating to the density of breeding species occurring within a sinkhole in central Italy obtained with a fine-grained and time-expensive sampling technique (mapping method). The results were compared with data sampled with the point counts method carried out in the same phenological period. We recorded 22 breeding species, all typical of meso-thermophilous forests and ecotonal habitats of hilly central Italy. Among them, two species (Turdus merula and Troglodytes troglodytes), typical of shady, undergrowth habitats, were recorded in the deepest part of the sinkhole (−70 m from the top). No significant differences emerged between the relative frequencies of the species obtained with the two methods, except for Luscinia megarhynchos (overestimated with the mapping method) and Aegithalos caudatus (underestimated). At the community level, the comparison of the two methods revealed similar values in univariate diversity metrics, Whittaker plots did not show a significant difference (ANCOVA test), and ordinary least squares regression between the frequencies showed a highly significant correlation. Therefore, in these peculiar habitats, data obtained from the two methods are comparable: since the point counts method needs lower sampling effort, it appeared to be more effective when compared to the mapping method to study these peculiar habitats.

“…The geometry and sequence of the images to be acquired for correct photogrammetric reconstruction using smartphones is the subject of lively debate in the scientific community, which has also developed useful guidelines [19]. For this experiment, the authors have decided to proceed according to their experience gained in previous experiments [1], [2], [10] and therefore to use mainly the intermediate focal length with a single horizontal strip, maintaining an overlap between one frame and the next never minor than 60 % in the longitudinal direction.…”

“…In fact, remains in densely populated areas have problems of accessibility because they are often located in underground areas with limited space [1]. On the other hand, remains in sparsely populated areas are often remote and difficult to reach with bulky equipment [2]- [6].…”

<p class="Abstract"><span lang="EN-US">Archaeological remains need to be geometrically surveyed and set in absolute reference systems in order to allow a "virtual visit" and to create "digital twins" useful in case of deterioration for proper restoration. Some countries (e.g., Peru) have a vast archaeological heritage whose survey requires optimized procedures that allow high productivity while maintaining high standards of geometric accuracy. A large part of Peru's cultural heritage is located in remote areas, at high altitudes and not easily accessible. For this reason, it is of great interest to study the possible applications of easily transportable instruments. In this study it was verified how the capabilities of the latest smartphones in terms of absolute differential positioning and photogrammetric acquisition can allow the acquisition of a geometrically correct and georeferenced three-dimensional model. The experimentation concerned a new survey of the Intihuatana stones at Machu Picchu and its comparison with a previous survey carried out with a much more complex laser scanning instrumentation. It is important to note that both the photogrammetric survey and the GPS/GNSS survey were carried out with the same smartphone taking full advantage of both features of the same mobile phone. Relative comparison to an existing point cloud provided differences of 2 millimeters in mean with an RMSE of 2 cm. The absolute positioning accuracy compared to a very large-scale cartography appears to be of the order of one metre as was expected mainly due to the high distance of the GPS/GNSS permanent stations.</span></p>
