2. Outline The Civil Protections requirements The CYCLOPS architecture
The gridded OGC Web Coverage Server
Use case: the RISICO forest fires assessment application
Porting RISICO in the CYCLOPS Grid infrastructure throug OGC Standard Web Services
CYCLOPS, as you probaby know, is a SSA founded in FP6 which aims to study a cyber infrastructure to connect the various European Civil Protections
Our work started from the analysis of the Civil Protection requirements
From these requirements we derived our CYCLOPS architecture
Recently we chosen a particular operative use case, the RISICO forest fires assessment application, and we ported it to the Cyclops Grid Infrastructure

3. From CP/GMES needs
Civil Protection and GMES applications/systems have specific requirements:
to share geospatial information that has complex characteristics:
Huge amounts of remotely-sensed observations, which are multidimensional and frequently updated
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
have access to computational power for working out simulation tasks or tasks for critical missions
To implement the strict data policy and the security requirements typical of dual systems (civil/military);
To formalise the knowledge required to analyse data and provide decision-makers with effective information
They need
At least

4. To GRID (Why to use Grid Platform for GMES applications?)
Provide physical resources to support heavy application workloads
Virtual Organization management
Provide a security infrastructure
Provide a quality of service agreement & monitoring infrastructure
We have chosen the grid tecnology to be the base of our architecture
The grid technology

10. RISICO use case: Forest fires risk assesment
RISICO is a forest fire risk forecasting system, operative for the Italian Civil Protection (DPC) since august 2003
It is developed by the CIMA Foundation for the DPC.
Such a system is made of two main models:
the fuel moisture model
the potential fire spread model
the fuel moisture model representing the dynamic behaviour of the distribution throughout the territory of the variable expressing the water contents of the vegetation;
the potential fire spread model evaluate the physical characteristics that a fire could assume, on the basis of the variables that locally determine the possibility of a successful ignition and fire propagation.

11. RISICO current implementation
RISICO current implementation runs on a single node on the CIMA premises
It accesses LAM and Earth Observation input data through heterogeneous protocol and interfaces

15. RISICO improvements
Flexibility: The geospatial services layer allow to:
Integrate new and heterogeneous input data.
Dynamically choose the spatial location and resolution of the run.
Be interoperable with other “standard-based” infrastructures.
Scalability. The grid infrastructure provides high processing and storage capabilities on-demand, allowing to:
Improve output data resolution.
Widen the covered area.
Improve the response time.
(Futures) Improve model complexity.
The introduction of the geospatial services layer allowed
