Chapter
Earth observation satellite systems play an important role in the provision of a wide range of information, especially in data-scarce regions. This role becomes extremely relevant during a disaster and when direct access to the affected area is difficult. This chapter provides an overview of the state of the art remote sensing techniques and tools...

Floating car data (FCD) is becoming more and more relevant for mobility domain applications, overcoming issues derived by the use of physical sensors (e.g. inductive loops, video observation, infrared and laser vehicle detection etc.), such as limited geographical distribution, measure inhomogeneities, limited or null coverage of minor roads. An in...
Conference Paper
Full-text available
The recent socioeconomic and environmental impacts of extreme flood events occurred in Europe are testimony to the disastrous consequences that such future hazards are likely to pose. Managing inundation risk requires prevention measures in close cooperation with Civil Protection authorities. This topic underlies the TRIBUTE (TRIgger BUffers for in...
Conference Paper
Full-text available
Early Warning Systems (EWS) for drought are currently underdeveloped compared to those related to other natural hazards. Both forecasting and monitoring of drought events are still posing challenges to the scientific community. In fact, the multifaceted nature of drought (i.e. hydrological, meteorological, and agricultural) is source of coexistence...

Early Warning Systems (EWS) for drought are currently underdeveloped compared to other hazards. In fact, the multifaceted nature of drought (i.e. hydrological, meteorological, and agricultural) necessitates a number of different ways to measure this phenomenon and its effects. In the present study an approach to identifying and monitoring drought e...

To evaluate accuracy of low resolution vegetation mapping for hydrological purposes, a comparative study of NDVI images derived from MODIS and Landsat 7 ETM+ data has been done. Main goal is to understand how effective MODIS images can be for vegetation characterization on large areas, as compared to the Landsat 7 ETM+ ones. In this paper a methodo...

The non-profit association ITHACA cooperates with the World Food Programme in order to define a global drought Early Warning System, mostly based on satellite data, with the scope of mapping critical areas that may be potentially subject to food crises. In 2010 the African regions of Sahel, especially Niger and Chad, faced a relevant food crisis du...
Conference Paper
Full-text available
A complete understanding of the complexity of physical-ecological-anthropogenic systems is the objective for scientists that are faced with Global Change and its consequences; managing and modelling the dynamic interaction of natural and social systems is the key for a clearer understand of actual environmental processes and how they may evolve in...
Article
Full-text available
Problem statement: The Normalized Difference Vegetation Index (NDVI) is the most extensively used satellite-derived index of vegetation health and density. Since climate is one of the most important factors affecting vegetation condition, satellite-derived vegetation indexes have been often used to evaluate climatic and environmental changes at reg...

Satellite images and GIS procedures are key elements for emergency management, especially in case of events hitting developing countries, more vulnerable to calamities and less prepared to face them. This article aims to show the procedure applied for the production of a cartography of flooded areas during the early impact phase; these activities a...

The ITHACA project ( Information Technology for Humanitarian Assistance, Cooperation and Action ) has the main goal to carry on operational and research activitie s in the field of geomatics for analysis, evaluatio n and mitigation of natural and manmade hazards. The project has been developed within an association founded by Politecni co di Torino...
Article
Full-text available
In this paper an innovative procedure based on satellite data aimed at the daily monitoring of snow covers is shown. Snow mapping is required to verify accessibility to those areas interested by catastrophic events. This need was expressed by the United Nations World Food Program (WFP). The research was developed within a collaboration agreement be...
Article
The cyclone Nargis that hit Myanmar in May 2008 and the earthquake occurred a month later in the Sichuan Chinese province, prove that natural disaster, although forecasted, may cause enormous damages and thousands of victims. ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action) operates in the field of early warning a...

a , O. Terzo b ABSTRACT: Short-term emergency response capacities, long-term risk reduction, development and environmental protection activities are sector where a Spatial Data Infrastructure (SDI) may strongly improve efficiency, facilitating access to geographically-related information using a minimum set of standard practices, protocols, and spe...
Article
Endorsement for a UN Spatial Data Infrastructure (UNSDI) to support coordinated efforts in the development and management of geo-spatial information was made by United Nations Geospatial Information Working Group (UNGIWG). World Food Programme (WFP), the largest humanitarian agency of United Nations, with its GIS operational units and the support o...
