Sperimentazione di smart device equipaggiati con GPS per guide multimediali di siti archeologici
2009
In last years several methodologies have been developed for guided tours of cultural heritage supported by handheld computers (PocketPC). The instruments used for this purpose are pocketPC, possibly equipped with a GPS receiver, which offer contents related to the place where the visitor is at that moment. This paper concerns the design of an innovative multimedia guide running on handheld computers to support the visit of archaeological sites. To that end the performances of various mobile phones and pocketPCs, equipped with low-cost GPS, have been tested; an application software developed by the Palermo research Unit has been installed into these devices to locate in real time the positio…
La crisi vista da un archeologo. Alcune considerazioni sulla situazione attuale dei beni culturali
2015
Il contributo esamina la situazione dell'archeologia siciliana negli anni della crisi, non solo dal punto di vista dell'assenza di adeguati finanziamenti, quanto dal punto di vista della politica di tutela e valorizzazione dei beni culturali e dell'investimento nella formazione. Il punto di svolta in negativo è individuato nella legge 40 del 2000 che abolì i ruoli tecnici nell'amministrazione dei beni culturali. Perché dai beni culturali si abbia un ritorno economico è necessario investire in maniera sinergica sul beni culturali stessi, sulle infrastrutture e sulla promozione del turismo.
Archéologie préventive. Une ressource pour la recherche et la mise en valeur?
2014
This paper discusses the results in applying Italy's law in preventive archaeology five years after the publication of the executive rules. It examines strenghts and weaknisses of the law, the latter identified in the scant attention paid to ancient topography and landscape archaeology. The role of university departments, the responsabilities of the Superintendences, the role of cooperatives of young archaeologists, the problems arising from the heavy costs in publishing the reserach results are examined. It is also proposed that the archaeological exavations and the programs of musealization be financed by a national fund fed by a percentage of the costs of all projects of public interest.
Levantamiento 3D para el estudio arqueológico y la reconstrucción virtual del Santuario de Isis en la antigua Lilybaeum (Italia)
2020
[EN] In recent years, the use of three-dimensional (3D) models in cultural and archaeological heritage for documentation and dissemination purposes has increased. New geomatics technologies have significantly reduced the time spent on fieldwork surveys and data processing. The archaeological remains can be documented and reconstructed in a digital 3D environment thanks to the new 3D survey technologies. Furthermore, the products generated by modern surveying technologies can be reconstructed in a virtual environment on effective archaeological bases and hypotheses coming from a detailed 3D data analysis. However, the choice of technologies that should be used to get the best results for dif…
Fornaci e produzioni del Golfo di Castellamare (Sicilia nord-occidentale)
2020
L’area del Golfo di Castellammare (Sicilia occidentale) è nota per le numerose fornaci di età romana. In questo articolo, si cercherà di ricostruire l’attività di un’officina destinata principalmente alla produzione di laterizi con bollo ΟΝΑΣΟΥ, databile fra III e I secolo a.C. Ricerche precedenti hanno permesso di riconoscere nel produttore di questi laterizi lo stesso Onasus Segestanus citato nelle Verrine di Cicerone e di localizzarne una possibile officina presso la Baia di San Cataldo. La scoperta di nuovi laterizi bollati e di scarti ceramici assume notevole importanza per una ricerca sugli ateliers ceramici del Golfo di Castellammare e della Piana di Partinico. Ne deriva un quadro ag…
BIM Modelling of Ancient Buildings
2018
In the last years, new procedures on design and management of constructions, based on 3D standardised models of building elements, have been proposed. It’s the case of Building Information Modelling (BIM) applications, that, differently from CAD ones, allow to work with libraries of 3D parametrical objects (smart objects) describing geometric, structural and material properties of building elements. This methodology is based on the Industry Foundation Classes (IFC) model, that represents a global standard for the building data exchange. Initially used for the design of new architectures, BIM methodology has been even more considered also for the management and the conservation of historical…
Coastal zone water quality: Calibration of a water-turbidity equation for MODIS data
2013
AbstractA nephelometric turbidity algorithm has been specifically calibrated for coastal waters in Sicily. To this purpose, intensive field campaigns were performed in July, August and September 2008. Measurements were collected in situ in three different gulfs. Statistical analysis suggests that field data should be spatially grouped but temporally separated; hence, new calibration parameters have been proposed.Turbidity retrieved by applying the algorithm using literature coefficients and the ones calibrated in situ are shown and compared. The comparison demonstrated that a specific calibration was necessary for quantitatively monitoring turbidity in Sicilian gulfs.
Integration of fuzzy logic and image analysis for the detection of gullies in the Calhoun Critical Zone Observatory using airborne LiDAR data
2017
Abstract The entire Piedmont of the Southeastern United States, where the Calhoun Critical Zone Observatory (CCZO) is located, experienced one of the most severe erosive events of the last two centuries. Forested areas were cleared to cultivate cotton, tobacco, and other crops during the nineteenth and early twentieth century and these land use changes, together with intense rainfalls, initiated deep gullying. An accurate mapping of these landforms is important since, despite some gully stabilization and reforestation efforts, gullies are still major contributors of sediment to streams. Mapping gullies in the CCZO area is hindered by the presence of dense canopy, which precludes the identif…
GEOMETRIC AND RADIOMETRIC ANALYSIS OF PAINTINGS
2010
The paper reports an overview of some experiences carried out by some Italian research groups (Politecnico di Milano, University of Palermo, Bruno Kessler Foundation in Trento) aimed to assess the conservation‟s state of some analysed paintings and provide useful information for further diagnostic applications. The activities were accomplished in interdisciplinary teams composed of photogrammetrists, surveyors, restorers and experts of non-destructive diagnostic techniques for Cultural Heritage. Two main aspects are considered: (i) the analysis of the radiometric contents using multispectral images and (ii) the 3D surveying for geometric deformation analysis by means of photogrammetry and l…
Studio delle potenzialità delle piattaforme UAV nel campo del rilievo dei Beni Culturali
2013
L'uso di piattaforme aeree senza pilota a bordo (UAV) sta diventando sempre più frequente nel campo del rilievo fotogrammetrico soprattutto grazie ai numerosi vantaggi che tali sistemi presentano rispetto alle classiche riprese di fotogrammetria aerea. Il lavoro condotto descrive i primi risultati ottenuti utilizzando sistemi UAV per il rilievo di Beni Culturali. Lo studio è stato svolto acquisendo alcuni dataset relativi a siti archeologici; tali dataset presentano caratteristiche differenti in relazione ai velivoli utilizzati, alle caratteristiche dei voli ed all’estensione delle aree rilevate. Il lavoro ha permesso di eseguite delle prime valutazioni sulla precisione metrica degli orient…
