Enabling Grids for E-sciencE EGEE-II INFSO-RI EGEE User Forum, Manchester, 11/5/ GMES, CP, GIS and OGC GMES is EU and ESA initiative with the aim of “establishing by 2008 a European capacity for Global Monitoring of Environment and Security” –GMES is a set of services for European citizens helping to improve their quality of life regarding environment and security The Report for the GMES Initial Period recognises the European Civil Protection (CP) as one of the GMES Service Categories –Services for risk management including prevention, monitoring and assessment at EU level of:  Natural hazards (floods, forest fires, landslides, earthquakes, etc…)  Technological hazards (industrial activities)  Maritime transport and security (oil spills, ice monitoring) GMES services based on Geographic Information System (GIS) –observation data from Earth Observation satellites and ground based information, but big fragmentation, lack of harmonisation, gaps in avail. –recent Geospatial Science developments provides the basis for GIS interoperability  Open Geospatial Consortium (OGC) as stdz. body

Enabling Grids for E-sciencE EGEE-II INFSO-RI EGEE User Forum, Manchester, 11/5/ Why GRID for CP? CP deals with emergency situations: forecasting, monitoring/warning, disaster management, assessment –Many different actors involved:  At administrative level: European, National, Regional, Provincial, Local  At mission level: emergency & rescue, health, police, environmental monitoring, meteorology, scientific observatories –They need to use and share heterogeneous and distributed resources (computing, data, services, knowledge, expertise, etc) in a coordinate and effective way –Many CP applications are high demanding (high performance, high throughput, intensive data access)  GRID is ideally suited to match CP needs

Enabling Grids for E-sciencE EGEE-II INFSO-RI EGEE User Forum, Manchester, 11/5/ CP application requirements Civil Protection and GMES applications/systems have specific requirements: –to access infrastructure, run models and search information in real-time (RT) or near-real-time (NRT):  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)
