This project, in themainframe of the program ―Civil Protection from forest fires‖, should take into account the institutional requirements, as: thenormative aspects in forest fires matter, the <strong>di</strong>stribution of responsibilities and competence of the authorities involved in thefollowing activities: planning and management of the land, dangerousness forecast and risk assessment, prompt fire detection,monitoring and management of the fire event, damage assessment. The principal user (reference user) of such a system wouldbe the Italian Dept. of the Civil Protection (DPC). Nevertheless, the system would be able to generate information useful forsupporting <strong>di</strong>fferent user types having the role of respon<strong>di</strong>ng, operationally, to the forest fire management accor<strong>di</strong>ng with theguideline and operational addresses in<strong>di</strong>cated by DPC. In particular, the objective of SIGRI is the development of productswhich can be useful to the fire fighting activities along all the phases which can be <strong>di</strong>stinguished in the fire contrasting activity:forecast, monitoring/detection, counteract/propagation pre<strong>di</strong>ction, damage assessment/recover. One of the constraints of theproject is that the products provided by the system should be mostly based on satellite imagery. Three test areas, namelyCalabria, Liguria and Sar<strong>di</strong>nia, have been selected. The present paper is devoted to present the objectives of such project andthe activities carried out in order to achieve them. In particular, the fire risk index developed within the project will be<strong>di</strong>scussed. The starting point for the development of the fire risk index is represented by the well known FPI (Fire ProbabilityIndex). To make such index more suitable to describe the very <strong>di</strong>fferent environmental con<strong>di</strong>tions which are typical of theEuropean reality and the Italian one in particular the effect of the solar illumination has been introduced by computing of theevapotranspiration (ET) and the equivalent water thickness (EWT). Moreover, an effort has been made to improve theknowledge of the vegetation types covering the area of interest with the objective of determining the correspondence betweenthese and the fire fuel types. The possibility of using hyperspectral images to classify the land cover by using a series ofvegetation in<strong>di</strong>ces capable to estimate <strong>di</strong>fferent vegetation characteristics (greenness, senescence, canopy water content, etc.)has been analyzed. This idea aims at exploiting the images which will be made available in the next future as consequence ofthe launch (possibly in 2013) of the satellite sensor PRISMA, funded by ASI. The utilization of these in<strong>di</strong>ces in theclassification approach should present the double advantage of provi<strong>di</strong>ng values not affected by illumination con<strong>di</strong>tions aswell as values <strong>di</strong>rectly linked to the characteristics of the vegetation as fire fuel. Other products of the project, like the realtimefire detection system based on geostationary sensor SEVIRI, the high resolution satellite images automated procedure forburned scar mapping, the fire simulation behaviour will also be illustrated.Keywords: satellite, remote sensing, fire detection, risk index, burned areasIl progetto pilota SIGRI (Sistema Integrato per la Gestione del Rischio Incen<strong>di</strong>) finanziato dall‘ASI (Agenzia SpazialeItaliana) prevede lo sviluppo <strong>di</strong> prodotti come l‘in<strong>di</strong>ce del rischio incen<strong>di</strong>, le mappe dei punti pericolosi in tempo reale e lastima delle aree incen<strong>di</strong>ate. Questo progetto, nell‘ambito del programma ―Difesa Civile contro gli incen<strong>di</strong> boschivi‖ dovrebbeprendere in considerazione i requisiti istituzionali, quali: gli aspetti normativi in materia d‘incen<strong>di</strong> forestali, la <strong>di</strong>stribuzionedelle responsabilità e competenze delle autorità coinvolte nelle seguenti attività: pianificazione e gestione del territorio,previsione della pericolosità e valutazione dei rischi, in<strong>di</strong>viduazione sollecita dell‘incen<strong>di</strong>o, monitoraggio e gestione dell‘eventoincen<strong>di</strong>ario, valutazione dei danni. L‘utente principale (utente <strong>di</strong> riferimento) <strong>di</strong> tale sistema sarebbe il <strong>Dipartimento</strong> Italianodella Protezione Civile (DPC). Ciononostante, il sistema sarebbe in grado <strong>di</strong> generare informazioni utili a sostenere <strong>di</strong>versi tipi<strong>di</strong> utenti che hanno il ruolo <strong>di</strong> rispondere operativamente alla gestione <strong>degli</strong> incen<strong>di</strong> boschivi, secondo le linee guida e gliin<strong>di</strong>rizzi operativi in<strong>di</strong>cati dal DPC. In particolare, l‘obiettivo del SIGRI è lo sviluppo <strong>di</strong> prodotti che possono rivelarsi utilialle attività antincen<strong>di</strong>o insieme a tutte le fasi che si <strong>di</strong>stinguono nell‘attività <strong>di</strong> contrasto all‘incen<strong>di</strong>o: previsione,monitoraggio/in<strong>di</strong>viduazione, contrasto/previsione della propagazione, valutazione del danno/risanamento. Uno dei vincolidel progetto è che i prodotti forniti dal sistema dovrebbero essere principalmente basati sulle immagini satellitari. Sono stateselezionate tre aree <strong>di</strong> sperimentazione, ovvero Calabria, Liguria e Sardegna. La presente relazione è de<strong>di</strong>cata a presentare gli18
