The European GMES project OSIRIS has been structured to answer to the following operational objectives.
    • Improve the constant monitoring of the environment and the management in real time of an environmental crisis.
    • Open the environmental domains offering to the end-users the capacity to know simultaneously situations of different nature, evaluate their interactions (weather forecast, water, air, etc) and better master the situations in case of crises.
    • Improve the security of the citizens and the rescue teams.

OSIRIS offers a three-dimensional set of services, sufficiently generic to address environmental requirements, but also any kind of security missions, thanks to its open and flexible system architecture.
Operational services: Facilitating the access and presentation for users to multi-domain sensor information. The services and data are accessible through a web portal or a Geographic Information System. Applications are delivered for operational supervision and exploitation purposes: generic display of data and alerts, tasking of sensors.
System services: Enabling the management of the configuration of the system and its evolution. The services provide a searching engine to identify the available sensors and observation capacities. They allow data workflow management, data processing, managing and orchestrating of processing means, and offer storage and access capabilities to the stored data, hiding the complexity of the underlying data sources involved. Services of fusion of information are offered here.
Sensor Services: Allowing accessing to raw sensor data and control of the sensors. Standardization is a very important step in order to reach interoperability, thus those services are based on the Sensor Web Enablement (OGC standards), adjusted for OSIRIS. Improvements were done in conjunction with OGC (especially for mobile sensors), and are still participating to the new revisions of the standards.
The services are grouped in several layers, the Sensor Services, near the sensors, being exploited by added value services: System Services. Operational Services can access the System Services as well as the Sensor Services.
