User oriented multidisciplinary approach to flood mapping: The experience of the Italian Civil Protection System

This paper describes two examples of synergistic management of EO based services for flood emergency monitoring. The first relates to the benefits of collaboration between decision makers, end users and experts reporting the case of the November 2014 Liguria and Po River flooding, when early activation, prior to the occurrence of the flood, was made possible and the second shows the benefits of the synergy between Sentinel-1 (S-1) and COSMO-SkyMed (CSK) contributing missions for monitoring floods at national scale. The two examples are referred to flood monitoring but the conclusions can be easily extended to other risks.
