The campaign was carried out in collaboration with the University of Costa Rica and Jet Propulsion Laboratory of the California Institute of Technology (Pasadena, California) and has allowed the acquisition of a number of measures through scientific instrumentation as miniaturized multi-gas, thermal cameras and spectro-radiometer. First analysis in terms of brightness temperature was carried out through Landsat and ASTER satellite data. In addition to the instrumental test, one of the objectives has been to verify the possibility of mounting a light payload on a quadcopter and fly it on areas of high gas flow to allow the acquisition of data security. First results are reported in this work while it is foreseen a more accurate analysis of the data obtained. campaign, some results using the spectro-radiometer ASD FieldSpec of optical labo...

The latter, which includes objects, building and sites with historical, architectural and/or engineering relevance, concerns the management, the preservation and the maintenance of the heritages within their surrounding environmental context, in response to climate changes and natural hazards (e.g. seismic, volcanic, landslides and flooding hazards). Within such a framework, the complexity and the great number of variables to be considered require a multi-disciplinary approach including strategies, methodologies and tools able to provide an effective monitoring of Cultural Heritages form both scientific and operational viewpoints. Based on this rationale, in this study, an advanced...

PRISMA is an Earth observation system with innovative electro-optical instrumentation which combines an hyperspectral sensor with a panchromatic medium-resolution camera. These instruments offer the scientific community and users many applications in the field of environmental monitoring, risk management, crop classification, pollution control, and Security. In this context Mt. Etna (Italy) has been choose as site for testing the sensor capability to assess volcanic risk. Thevolcanic calibration and validation activities comprise the managing of a large amount of in situ hyperspectral data collected during the last 10 years. The usability and interoperability of these datasets represents a task of ASI-AGI project. For this purpose a database has been created to collect all the spectral signatures of the measured volcanic surfaces. This process has begun with the creation of the metadata structure compliant with those belonging to some standard spectral libraries such as USGS ones. Each spectral signature is described in a table containing ancillary data such as the location map of where it was collected, description of the target selected, etc. The relational database structure has been developed WOVOdat compliant. Specific tables have been formatted for each type of measurements, instruments and targets in order to query the database through a user-friendly web-interface. The interface has an upload area to populate the database and a visualization tool that allows downloading the ASCII spectral file and also visualizing an interactive graph where the spectral range to plot can be selected by the user. Ground campaign: Fieldspec acquisition In order to acquired the spectral signatures of the volcanic products, on each measurement sites, the volcanic surfaces (targets) have been sampled using a Portable Field Spectrometer (Fieldspec). The Fieldspec instrument measures the reflected spectral solar radiation in the wavelength range (350-2500) nm. The radiation collected by the entry optics is projected into a holographic diffraction grating where the wavelength components are separated and reflected into the light sensitive detectors. The photoelectric currents are converted to a voltage and digitized by a 16 bit analog to digital converter. The digital data are transferred to a personal computer connected to the instrument. In real time data are available to processing, visualization and storage by the controlling software. The spectral wavelength range is covered by 3 separate spectrometers: the first one operates between 350 and 1050 nm with a spectral resolution of approximately 3 nm and a sampling step of 1.4 nm. The other 2 spectrometers cover the region from 900 to 1850 and 1700 to 2500 nm, respectively. In these regions the sampling interval is 2 nm and the resolution varies between 10 to 12 nm. Solar reflected energy is collected through a bundle of bare optic fiber under a conical field of view of 25 o . Fieldspec can acquire both radiance and reflectance data. The instrument provides the reflectance value calculated as ratio between the incidence solar radiation reflected from the surface target and the radiation reflected by a reference surface. Spectralon panel regarded as a Lambertian reflector is used in the field as a reference surface. Fieldspec may be operated with different lenses that control the field of view: in this survey the bare fiber was used resulting in a surface area of about 40x40 cm when instrument is about 60 cm above the target. The instrument was always nadir oriented and attention was devoted to collect data at maximum sun elevation to avoid shadowing effects.

Coastal retreat, erosion and storm surges are yet posing serious threats to archaeological and historical structures built along the coastal zones of this region. In order to assess the coastal changes by the end of 2100 under an expected sea level rise of about 1 m, a detailed determination of the current coastline position and the availability of high resolution DSM, is needed. This paper focuses on the use of very high-resolution UAV imagery for the generation of ultra-high resolution mapping of the coastal archaeological area of Pyrgi, near Rome (Italy). The processing of the UAV imagery resulted in the generation of a DSM and an orthophoto, with an accuracy of 1.94 cm/pixel. The integration of topographic data with two sea level rise projections in the IPCC AR5 2.6 and 8.5 climatic scenarios for this area of the Mediterranean, wer...

It integrates ground-based, airborne and spaceborne remote sensing tools with geophysical and in situ surveys to provide the multi-spatial (regional, urban and building scales) and multi-temporal (long-term, short-term, near-real-time and real-time scales) monitoring of test areas and buildings. The measurements are integrated through web-based GIS and 3D visual platforms to support decision-making stakeholders involved in urban planning and structural requalification. An application of this system is presented over the Calabria region for the town of Cosenza and a test historical complex.

Such events occur with a frequency of a few per year (major events) to a few per century (paroxysms).During such events the risk level close to the volcano enormously increases, and thevolcano acvity represents a danger for inhabitants and for the many tourists whofrequently crowd the island. The paroxysms occurred in 2003 and 2007 represent for the scienfic community case studies of great relevance for understanding the dynamics associated to such events. Parcularly, the event of April 5th, 2003, has clearly shown the destrucve potenal of the volcano. Besides major events and paroxysms, lava flows somemes mark changes in the usual volcano acvity, oen represenng phases of transion in volcanic acvity and possibly ancipang the occurrence of paroxysms.The aim of this project is that of understanding and recognising short te...
