4. nativi@imaa.cnr.it 4 Participants Civil Protection Agencies – CP-CH (Civil Protection of Chania Prefecture) – DDSC (Direction de la Défense et de la Sécurité Civiles) – DPC (Dipartimento della Protezione Civile) – SNBPC (Serviço Nacional de Bombeiros e Protecção Civil) Scientific/Technological partners – EMA (Ecole des Mines d' Ales ) – IMAA-CNR (Istituto di Metodologie per lAnalisi Ambientale del Consiglio Nazionale delle Ricerche) – INFN (Istituto Nazionale di Fisica Nucleare) – TEI-CR (Technological Educational Institute of Crete)

5. nativi@imaa.cnr.it 5 Rationale Civil Protection and GMES applications/systems have specific requirements: – to access infrastructure, run models and search information in a real-time (RT) or near-real-time (NRT) way privileging time of response instead of accuracy – to control sensors networks and acquisition systems and modify their acquisition strategy and processing chain – to share geospatial information that has complex characteristics: Huge amounts of remotely-sensed observations, which are multidimensional and frequently updated – To formalise the knowledge required to analyse data and provide decision-makers with effective information – To implement the strict data policy and the security requirements typical of dual systems (civil/military);

6. nativi@imaa.cnr.it 6 Why to use Grid Platform for GMES applications? 1. Provide physical resources to support application workloads a. Provide the computational power for working out simulation tasks or tasks for critical missions (see job management) b. Provide near real time access to data resources (see data management) 2. Virtual Organization management a. Grid information system b. Resource cataloguing and sharing 3. Provide a security infrastructure 4. Provide a quality of service agreement & monitoring infrastructure 5. Provide an infrastructure to distribute VO policy management on its nodes

7. nativi@imaa.cnr.it 7 Objective & Research Strategies Conceive a complete Grid-based platform supporting Civil Protection/GMES applications – The CYCLOPS platform Many open issues must be addressed – Integration & Interoperability (with EGEE platform) Implement Spatial Data Infrastructures (SDI) services in the EGEE platform Integrate sensor networks and acquisition systems in the EGEE platform – Define specific services for GMES/CP applications Define advanced services (knowledge-based services, Quality-of-Service management, etc.) Define Data Policy and Security services Define generic Business Logic, Presentation and Fruition services

8. nativi@imaa.cnr.it 8 CYCLOPS Main Activities Definition of research and innovation strategies – Analysis of CP systems – EGEE Request for Enhancements – Research strategies for enabling CP applications on Grid infrastructure – Guidelines for CP innovation towards the adoption of Grid technologies Cross-dissemination between GRID (EGEE) community and GMES (Civil Protection) community. – Seminars, workshops, tutorials directed to CP personnel – Reports to EGEE Working Groups

9. nativi@imaa.cnr.it 9 Standardization Communities GRID community – test and validate, the middleware re-engineered by EGEE and EGEE-2 in compliance with the current open standards (GGF, OMII Europe) Geospatial Information community – INSPIRE (The INfrastructure for SPatial InfoRmation in Europe ) – GEOSS (Global Earth Observation System of Systems) – OGC/ISO (Open Geospatial Consortium) Risk and Crisis Management Sensor Web Enablement Earth Observation OWS: WCS, WFS, CS/W, CTS, WPS, … Civil Protection community – GMES (Global Monitoring for Environment and Security)

10. nativi@imaa.cnr.it 10 Selected use case: Flood Forecast Involves heavily meteorology and hydrological modelling Involves many sensors (floods gauges, rain radars, meteo sats) Linked to GMES flash flood anticipation service

11. nativi@imaa.cnr.it 11 Selected use case : Large forest fire propagation Propagation models used on the field are simplistic due to computational limitations More sophisticated models require heavy computations, large number of field and meteo parameters French research project PAREFEU, link with GMES service PREVIEW After Sero-Guillaume et al.
