Forest fires are one of the most dangerous events, causing serious land and environmental degradation. Indeed, besides the loss of a huge quantity of plant species, the effects of fires can go far beyond: desertification, increased risk of landslides, soil erosion, death of animals, etc. For these reasons, mathematical models able to predict fire s...
Conference Paper
In Italy, at present, the cadastral cartography and every related service to citizen are managed by the Revenue Agency. It is important to remember the era of cadastral mapping formation, which has undergone many changes over time, dictated by the continuous evolution in the survey discipline. It is important to remember that the original maps were...
Conference Paper
Geophysical measurements provide a massive data source to investigate the behaviour of active volcanoes like Mt. Etna (Sicily, Italy). Here we present a new interface to visualize gravity variations, observed through time-lapse measurements, based on the Google Maps service, a choice motivated by its ease of use and the user-friendly interactive en...

The proposed...
Article
In recent years, the use of remote sensing in archeology has rapidly grown, having being proven particularly useful for landscape archaeology investigations. The quality of results obtained through remote sensing mainly depends on the number of bands that can be exploited, the spatial and spectral resolution of imagery and the methodology used. In...
Chapter
It has been largely proven that Geographic Information Systems (GIS) provide a valuable tool as Decision Support System (DDS) for the assessment and management of environmental hazards. In this work we used the GIS technologies to simulate scenarios associated to possible tsunamis in the Ionian Sea, involving the territory of Acireale (Catania), in...
Article
Biomasses are materials of organic origin that can be used for the production of energy. Among the renewable energy sources, a prominent role is played by woody biomass, which can be retrieved from existing forests or plantations governed in short or middle rotation coppice, the so-called Short and Medium Rotation Forestry. The main environmental b...
Chapter
Multispectral and hyperspectral remote sensing have significantly improved territorial surveys and mapping. However aerial images are often expensive being acquired through aircraft and satellite sensors. Furthermore, the processing and classification of these images need commercial software that increases the entire cost of the analysis. For these...

A rockfall analysis at one of the most relevant cultural heritage sites of northeastern Sicily (Italy) is presented herein with the aim of assessing the hazard arising from the unstable conditions of the rock cliff of Taormina city, upon which the Saracen Castle is perched on its top. Several rockfalls affected this area in the latest years, repres...
Conference Paper
The Structure From Motion (SFM) is a technique applied to a series of photographs of an object that returns a 3D reconstruction made up by points in the space (point clouds). This research aims at comparing the results of the SFM approach with the results of a 3D laser scanning in terms of density and accuracy of the model. The experience was condu...
Conference Paper
We deal with the theme of the simulation of risk analysis using a technological approach based on the integration of exclusively free and open source tools: PostgreSQL as Database Management System (DBMS) and Quantum GIS-GRASS as Geographic Information System (GIS) platform. The case study is represented by a seismic land in Sicily characterized by...

Conference Paper
The flight planning for Unmanned Aerial Vehicles (UAVs) is extremely useful both in terms of planimetry and altimetry. Regarding the planimetry, it is needed to reach and operate on the region of interest, while for the altimetry, it is functional to plan the flight altitude as function of the obstacles along the navigation path. In this paper we p...
