Il rilievo del sito archeologico di Eraclea Minoa: valutazioni metriche sull’impiego di un Sistema Aeromobile a Pilotaggio Remoto (SAPR)
2017
Il lavoro condotto ha affrontato le problematiche connesse con le fasi di acquisizione e elaborazione dei dati ottenuti da SAPR con la finalità di dimostrare il grande potenziale di questi sistemi per la fotogrammetria aerea di prossimità. Il lavoro ha previsto lo studio delle principali problematiche attraverso prove sperimentali condotte durante le fasi del rilievo del sito archeologico di Eraclea Minoa (Agrigento). In particolare, i dati acquisiti hanno permesso di analizzare in dettaglio le procedure di pianificazione ed esecuzione di voli e le procedure di orientamento in relazione anche alle metodologie di rilievo dei punti di appoggio. La fase di pianificazione del volo è stata studi…
Assessing the performance of a large-scale irrigation system by estimations of actual evapotranspiration obtained by Landsat satellite images resampl…
2019
Abstract Remote sensing techniques allow monitoring the Earth surface and acquiring worthwhile information that can be used efficiently in agro-hydrological systems. Satellite images associated to computational models represent reliable resources to estimate actual evapotranspiration fluxes, ETa, based on surface energy balance. The knowledge of ETa and its spatial distribution is crucial for a broad range of applications at different scales, from fields to large irrigation districts. In single plots and/or in irrigation districts, linking water volumes delivered to the plots with the estimations of remote sensed ETa can have a great potential to develop new cost-effective indicators of irr…

Paesaggi urbani e rurali nella Sicilia di Tommaso Fazello: note di geomorfologia e archeologia
2014
The studies of Sicilian ancient landscapes, the histories of sites, towns and marks of antiquity, have necessarily to trace back to Tommaso Fazello’s book. Before him, nobody else had offered such a detailed depiction of ancient Sicily, and the methodology of his research is still very authentic. In addition to describing the ruins of ancient cities and identifying them (Selinunte is for instance a very special case), one could affirm that Fazello’s interest was also in the natural characterization and transformation of both rural and urban landscapes. In brief, it is possible to define the figure of Fazello in terms of a geoarchaeologist ante litteram. The descriptions of some towns – the …

Selinunt, Sizilien. Forschungen in Selinunt, Teil 1. Ein neues Modell für die Stadt Selinunt. Die Feldarbeiten des Jahres 2021
2022
Since 2021, the German Research Foundation has been funding a new interdisciplinary field project to investigate the urban fabric of the Greek colony of Selinous in a spatially comprehensive and diachronic perspective. The project aims at extending the existing model of the ideal Greek city by considering also the historically conditioned fractures in the urban development and the multiple transformations of the living space between the 7th and 3rd century BCE. This is to be pursued by large scale archaeological, geophysical and geoarchaeological prospections, small excavations in selected areas and the thorough study of the finds and archaeobiological remains. This is a report about the fi…
Radiometric and geometric evaluation of the capabilities of the new airborne digital photogrammetric sensors
2008
In this paper the theoretic and practical points of view about the applications of the modern digital airborne sensors in the photogrammetry and remote sensing fields are described. The first part of the paper describes the theoretic matter, the second one shows the first results regarding the carried out elaborations on an image of Palermo acquired by digital airborne sensor LH System ADS40. Besides the research has examined most of sides regarding the trilinear sensor and it has highlighted the capabilities and limitations respect to the traditional analogical system and the matricial CCD sensor.
Use of CORS Time Series for Geodynamics Applications in Western Sicily (Italy)
2020
In the last few decades, the use of GNSS Continuously Operating Reference Station (CORS) networks allowed improving the accuracy of real-time positioning and post-processing positioning. In this way, several applications have been performed including remote sensing, agriculture, cultural heritage and geodynamics studies. The latter have been developed analysing CORS time-series and consistent data over long periods were needed to validate the results. In Italy, specifically in Sicily, two CORS networks were be used to monitor the geodynamics motions: the Istituto Nazionale di Geofisica e Vulcanologia (INGV) GNSS CORS network in the eastern part and the University of Palermo (UNIPA) GNSS COR…
SOFIA: a decision support System for the Optimization of the biomass supply chain and Forest Integrated management in protected areas
2019
A decision support System for the Optimization of the biomass supply chain and Forest Integrated Management in protected areas (SOFIA) is presented. All functionalities have been developed in Python language embedded in the open-source QGIS 3.6 software. Two models were implemented with an approach and methodology based on free and open source software (QGIS, GRASS, SAGA, GDAL). The main aim of SOFIA is to support the Madonie Regional Natural Park authority and forest managers in decision-making processes to assess the costs and benefits in the energy production from residual agro-forestry biomass, as well as for determining the optimum plant size (and power) for energy and heat production …
