Towards a sensor web architecture for Disaster management: Insights from the Namibia flood pilot

The Group on Earth Observations, GEO, has identified the need to improve disaster risk management by providing timely information relevant to the full disaster management cycle of mitigation, preparedness/warning, response and recovery. The Committee on Earth Observing Satellites, CEOS, as the satellite arm of GEO, has recognized the important role that remote sensing contributes to all phases of the disaster management cycle. Activities to address the satellite information needs and gap analysis for disaster management systems are ongoing. This paper reports on results from two such activities, the southern Africa Flood and Health Pilot addressing annual floods in Namibia, and the GEOSS Architecture for Disasters analysis to enhance the use of satellite data. Direct interaction with Namibian hydrologists to experiment with satellite and in situ data products has helped inform the disasters architecture, providing lessons learned and best practices for the GEO societal benefit areas.
