The SRV project is funded by Italian Space Agency (ASI) in the frame of Earth Observations activities for natural risks management included in the National Space Plan 2003-2005. The SRV Project started in January 2007 and is coordinated by INGV which is responsible at national level for the volcanic monitoring by means of geophysical ground networks. The objective of the project is aimed to the implementation of pre-operative version for a system based on EO data analysis and ground measurements integration to support the volcanic risk monitoring activities of Italian Civil Protection Department. The project philosophy is to realize a prototype already analyzed in previous feasibility study in 2004. A very important issue regarding the product implementation of SRV is the achievement of End-User requirements, which will guarantee the compliance between the system modules and out-puts with the operative request of the End-User during the different volcanic risk phases: 1) Knowledge and Prevention, 2) Crisis, 3) Post Crisis. The different products will be developed on three test sites (Etna, Vesuvio and Campi Flegrei) accessible by WEB-GIS interface. It will be important to compare the SRV development with other similar or complementary project developed in Europe and worldwide in order to define common standards for products and procedures to facilitate the use to the final End Users.
