Services from the Continuously Operating Reference Stations (CORS) of the Global Navigation Satellite System (GNSS) provide data and insights to a range of research areas such as physical sciences, engineering, earth and planetary sciences, computer science, and environmental science. Even though these fields are varied, they are all linked through the GNSS operational application. GNSS CORS have historically been deployed for three-dimensional positioning but also for the establishment of local and global reference systems and the measurement of ionospheric and tropospheric errors. In addition to these studies, CORS is uncovering new, emerging scientific applications. These include real-time monitoring of land subsidence via network real-time kinematics (NRTK) or precise point positioning (PPP), structural health monitoring (SHM), earthquake and volcanology monitoring, GNSS reflectometry (GNSS-R) for mapping soil moisture content, precision farming with affordable receivers, and ze...

The paper presents a digital approach to the reconstruction and analysis of two small-sized fragments of <i>louteria</i>, a kind of large terracotta vase, found during an archaeological survey in the south of Sicily (Italy), in the area of Cignana near the Greek colony of Akragas (nowadays Agrigento). The fragments of <i>louteria</i> have been studied by an image-based approach in order to achieve high accurate and very detailed 3D models. The 3D models have been used to carry out interpretive and geometric analysis from an archaeological point of view. Using different digital tools, it was possible to highlight some fine details of the <i>louteria</i> decorations and to better understand the characteristics of the two fragments. The 3D models provide also the possibility to study and to document these archaeological finds in a digital environment.

The diffuse data fruition of archaeological hypogeum sites still represents a challenge due to their limited accessibility and their preservation and maintenance issues. This implies that the fruition of these peculiar archaeological sites is often possible through digital reconstructions and interactive web navigation systems. The survey methodologies based on terrestrial laser scanning and photogrammetry allow making accurate and detailed digital reconstructions of these sites that are useful for virtual fruition purposes. In addition, many different systems can be used for remote web navigation and fruition. This work presents a possible solution for the virtual fruition of archaeological hypogea with a multiscale 3D web navigation system based on WebGL open-source technology. The system has been implemented for the Roman hypogeum of Crispia salvia, located in Marsala (southern Italy). The hypogeum belongs to the Archaeological Park of Lilibeo-Marsala and is considered one of the...

The paper shows the results of the research activities carried out by the Department of Engineering at the University of Palermo (Italy), which assessed the application of the Heritage Building Information Modelling (HBIM) methodology through a Scan-to-BIM approach to two local churches belonging to the medieval period. This project was motivated by a renewed interest from the city administrators towards the conservation of cultural heritage dating back to the Arab-Norman domination in Sicily since one of the two buildings was included in the UNESCO World Heritage Sites list in 2015. The morpho-typological style of the churches has been acquired by high-detailed 3D surveys, which provided the base for two HBIM models suited to render the peculiarity of these buildings at their best. The BIM environment allowed both the geometrical representation of all the architectural elements and their further enrichment with the integration of non-geometric data and semantic signification throug...

The work shows the results of testing conducted from 2008 to 2009 within the Network-based RTK GNSS of University of Palermo. The network is composed of eight Continuously Operating Reference Stations (CORS) located in western Sicily and managed by a Control Centre located at the Dipartimento di Rappresentazione (DIRAP) of University of Palermo. The main goal of the work is to verify the reliability of the CORS network (successful tests, failed initialization time, satellite configurations) and the accuracy of measurements positioning using VRS, FKP and Nearest Station techniques. The reliability was considered the probability that the operator can correctly determine its position within the CORS network, depending on the method of calculation used in surveys conducted in different areas and in different days. Accuracy was determined by comparing the coordinates of several points calculated in post-processing and NRTK surveys

This paper describes an experiment concerning a ‘historical heritage-conscious’ data recording system. The experiment was part of a wider research, which was conducted into the archaeological site of Piazza Armerina, Sicily, and comprised the surveying, recording and classification of various kinds of information. Notably, the main aims of the research into the data recording system were: a) devising an information system capable of easily recording and organising survey data such as text, drawings, images and animations, for the use of researchers and technicians; b) promoting a multidisciplinary dialogue among different disciplines, thus obtaining some integration among different kinds of documents and projects; c) verifying the effectiveness of a hyper-textual system as regards procedures for storing survey data; d) supporting researchers and technicians when investigating an archaeological site.

The development of automatic procedures in close-range photogrammetry is an interesting research topic today especially for the images orientation. The integration of Computer Vision and photogrammetric techniques allows the automation of the process. These techniques have allowed the development of scientific and commercial softwares to automate the process of orientation. The aim of the study is to test the potential of automated procedures available in the software PhotoModeler Scanner 2011 by EOS Systems. These procedures use the strategy called "Structure from Motion", that automatically orients a large number of images. Different objects were considered for the test in terms of shape, size, materials and architectural details.

The work aims to investigate the main steps of a virtual reconstruction process of ancient statues, inspecting theoretical and technical approaches. Two fragmentary Roman statues from the "Sanctuary of Isis", inside the Archaeological Park of Lilibeo-Marsala (Italy), were chosen as a case study. Trying to preserve the original artwork authenticity and the transparency of the reconstruction method, a workflow was developed following three steps: 1) 3D survey and reality based model production; 2) evaluation of reconstruction hypotheses based on a rigorous selection of reference sources; 3) 3D modelling and source-based model creation. Three models for multiple visualization purposes were carried out: a high-resolution reality-based model for documentation and detailed specialist analyses, a real-integrated model for scientific purposes in which it is possible to visually distinguish the surviving fragments from the modelled ones through a partial texture and an ideal model ...

Il lavoro \ue8 finalizzato allo studio di procedure fotogrammetriche speditive per il controllo e il monitoraggio del degrado superficiale di manufatti architettonici attraverso l\u2019utilizzo di archivi fotogrammetrici storici. La ricerca \ue8 stata condotta utilizzando l\u2019archivio fotogrammetrico storico del Dipartimento di Rappresentazione dell\u2019Universit\ue0 di Palermo, costituito negli anni settanta e formato da circa seicento lastre di vetro realizzate con le bicamere Wild C120 e C40. Nell\u2019archivio sono conservate numerose prese fotogrammetriche di importanti palazzi e monumenti di Palermo e della Sicilia occidentale. L\u2019archivio storico ha permesso di effettuare un primo studio per l\u2019applicazione di procedure fotogrammetriche che, in maniera abbastanza semplice e rapida, consentissero di eseguire delle analisi comparative delle trasformazioni avvenute nel corso degli anni. L\u2019applicazione \ue8 stata condotta su due differenti edifici presenti a Palermo: Palazzo Bordonaro, un palazzo nobiliare ubicato nel centro storico, e la chiesa di Santa Maria di Ges\uf9. Gli elaborati fotogrammetrici prodotti dai rilievi fotogrammetrici eseguiti negli anni settanta e da nuovi rilievi condotti nel 2008 hanno consentito di eseguire un\u2019analisi dello stato di degrado superficiale dei manufatti

The survey of archaeological sites by appropriate geomatics technologies is an important research topic. In particular, the 3D survey by terrestrial laser scanning has become a common practice for 3D archaeological data collection. Even if terrestrial laser scanning survey is quite well established, due to the complexity of the most archaeological contexts, many issues can arise and make the survey more difficult. The aim of this work is to describe the methodology chosen for a terrestrial laser scanning survey in a complex archaeological environment according to the issues related to the particular structure of the site. The developed approach was used for the terrestrial laser scanning survey and documentation of a part of the archaeological site of Elaiussa Sebaste in Turkey. The proposed technical solutions have allowed providing an accurate and detailed 3D dataset of the study area. In addition, further products useful for archaeological analysis were also obtained from the 3D ...

In this study, a new method to compare rebuilt surfaces of hulls of sailing yachts is presented. In particular, the considered rebuilt surfaces are created through classic reverse engineering approaches. The new method has been developed by means of Grasshopper, a free generative algorithms editor that can be used as plugin of Rhinoceros, one of the most widespread free-form modelling software. In particular, two different algorithms have been developed: the first one allows controlling the quality of the rebuilt surfaces, the second one, instead, allows to measure the deviations between the original CAD Model and the rebuilt surface of the hull. A case study related to the hull of a small sailing yacht is also presented. The obtained results have demonstrated the efficiency of the new proposed low-cost method

Thanks to recent technological developments in 3D surveys, computer graphics and virtual reality, new scenarios have been opened for the documentation and enhancement of ancient sculptures. When not totally preserved, sculptures can be digitally reproduced, modified and visualized to simulate their physical or virtual reconstruction in a non-invasive way for specialists or for dissemination aims. The virtual sculptural reconstruction process starts usually from the 3D survey of real fragments, and then continues by integrating missing parts with 3D modelling techniques by means of source evaluation. Along with primary data sources (reality-based model), secondary data sources (photos, drawings and 3D models of similar sculptures) can be directly used in the reconstruction process. This approach has a double advantage of making the reconstruction activities easier and less arbitrary, contributing to a decrease in the degree of uncertainty for the sculptural reconstruction work, also ...

The Temple of Olympian Zeus in Agrigento (Italy) was one of the largest temple and at the same time one of the most original of all the Greek architecture. We don’t know exactly how it was because the temple is now almost completely destroyed but it is very well-known for the presence of the Telamons. The Telamons were giant statues (about 8 meters high) probably located outside the temple to fill the interval between the columns. In accordance with the theory most accredited by archaeologists the Telamons were a decorative element and also a support for the structure. However, this hypothesis has never been scientifically proven. One Telamon has been reassembled and is shown at the Archaeological Museum of Agrigento. In 2009 a group of researchers at the University of Palermo has begun a study to test the hypothesis that the Telamons support the weight of the upper part of the temple. The study consists of a 3D survey of the Telamon, to reconstruct a detailed 3D digital model, and ...

The paper describes the first results of a study, supported by an Italian research project “Integrated Inertial Positioning Systems in Aerial Photogrammetry” on the potential use of these techniques for production of digital large scale orthophotos. The study has been done with aerial photographs collected from two different flights executed in Sicily: the former, relating to the city of Palermo, at average scale of 1:9300; the latter, over the city of Catania, at average scale of 1:2000. For both flights the orthorectification was carried out by direct georeferencing methods and by traditional photogrammetric techniques, using ground control points surveyed by means GPS techniques and aerial digital triangulation. The orthophotos generated by both methods were compared between themselves checking the influence of integrated sensors on the accuracy of the final product.
