ISCRAM 2012 #123 ISCRAM 2012 #123 Presentation Transcript

  • Integrating National Tsunami Early Warning Systems towards Ocean-Wide System-of-Systems NetworksMatthias Lendholt [1], Martin Hammitzsch [1], Miguel A. Esbri [2] [1] German Research Centre for Geosciences (GFZ), Germany [2] ATOS Research, Spain
  • Motivation• Increasing number of national tsunami early warning systems (TEWS)• Increasing number of Crisis Management Information Systems (CIMS)• Research about information systemsDo we design + develop + implement + deploy interoperable information systems that are capable of system to system communication?Or do we create more and more isolated islands?
  • Overview• Introduction• Challenge• Results• Reference implementation• Outlook
  • UNESCO Tsunami Programme• UNESCO Intergovernmental Oceanographic Commission (IOC) Tsunami Programme: o Objective: The IOC Tsunami Programme aims at reducing the loss of lives and livehoods that could be produced worldwide by tsunamis. o Four Intergovernmental Coordination Groups (ICG) corresponding to the regions Pacific, Caribbean, Indian Ocean and Mediterranean have been established to address particular regional needs
  • UNESCO Tsunami Programme• Main objective IOC Tsunami Programme: The integration of national TEWS to ensure information exchange during tsunami events.  ICG Implementation plans• IOC ICG/IOTWS, 2008: Implementation Plan “… the establishment of a coordinated regional warning system for the entire Indian Ocean basin, through the establishment of a network of National inter- operable Warning Centres.”
  • ICG Implementation plan• Goal: develop systems-of-systems o Based on Standard Operating Procedures (SOP) • Legal aspects • Workflows o Standardized ICG warning products (bulletins) • Content: What, Where, When • Format: Plain ASCII text designed for FAX transmission • No protocols, technologies, encodings o Standardized ICG spatial reference schemas • Coastal Forecast Zones • Coastal Forecast Points
  • ICG/IOTWS Coastal Forecast Zones• Coastal Forecast Zones (CFZ) introduced to ensure interoperability between TEWS
  • Challenge• Develop a communication model to interlink/integrate national TEWS: 1. According to UNESCO IOC guidelines 2. Accounting UN International Strategy for Disaster Reduction (ISDR) recommendations 3. Based on standards of the emergency management domain 4. Applying system-of-systems engineering• Best practices / design philosophy: o Keep it simple o No proprietary technology o Open standards, open source software
  • Information gathering What are the needs and requirements? Which information must/must not be shared? Which technologies must/must not be used?• Experiences from preceding projects o GITEWS (German Indonesian Tsunami Early Warning System)• Literature work o IOC / ICG guidelines, implementation plans, … o ISDR recommendations o Other TEWS related research o Crisis Information Management Systems (CIMS) in general• Survey among experts o Questionnaires, Interviews, …
  • General public Legal Aspects §§§ Cultural background, capacity buildingOperators Technologies
  • Identified Workflows1. National Centres (NC) share sensor observations2. Wide Area Centre (WAC) runs ocean wide tsunami simulation3. WAC sends warning messages (IOC bulletins) to NCs Wide Area Centre
  • National Centres National CentreNational Centre Thailand Sri Lanka National Centre Indonesia
  • Wide Area Centre Infrastructure National CentreNational Centre Thailand Sri Lanka National Centre Indonesia Wide Area Centre
  • Earthquake Event National CentreNational Centre Thailand Sri Lanka National Centre Indonesia Wide Area Centre
  • Observation by NC National CentreNational Centre Thailand Sri Lanka National Centre Indonesia Wide Area Centre
  • Dissemination on National Level National CentreNational Centre Thailand Sri Lanka National Centre Indonesia Wide Area Centre
  • Sending observations to WAC National CentreNational Centre Thailand Sri Lanka National Centre Indonesia Wide Area Centre
  • Forwarding to NCs National CentreNational Centre Thailand Sri Lanka National Centre Indonesia Wide Area Centre
  • Running ocean wide tsunami forecast  IOC bulletin National CentreNational Centre Thailand Sri Lanka National Centre Indonesia Wide Area Centre
  • Delivery of warnings to NCs National CentreNational Centre Thailand Sri Lanka National Centre Indonesia Wide Area Centre
  • Dissemination on National Level National CentreNational Centre Thailand Sri Lanka National Centre Indonesia Wide Area Centre
  • Information Encoding1. Sensor Observation exchange  SWE (Sensor Web Enablement) messages • XML • OGC (Open Geospatial Consortium) Standard • Used by GITEWS and many others sensor related information systems2. Ocean wide bulletins  CAP (Common Alerting Protocol) • XML • OASIS (Organization for the Advancement of Structured Information Standards) • Widely used in Canada, US and Australia3.Envelope / addressing  EDXL-DE (Emergency Data Exchange Language-Distribution Element) • XML • OASIS
  • Example message: EDXL-DE envelope<EDXLDistribution xmlns=urn:oasis:names:tc:…><distributionID>urn:org:dews_online:WAC.IO:CAP6_1</distributionID> <senderID>urn:org:dews_online:WAC.IO</senderID> <dateTimeSent>2011-03-10T17:50:28.202+00:00</dateTimeSent> <distributionStatus>Actual</distributionStatus> <distributionType>Report</distributionType> <keyword> <valueListUrn>http://www.dews-online.org/urn/c2c</valueListUrn> <value>BULLETIN</value> </keyword> <contentObject> <contentDescription>CAP message generated by DEWS WAC.IO</…> <incidentID>urn:org:dews_online:WAC.IO:6</incidentID> <incidentDescription>Tsunami Warning</incidentDescription> <xmlContent> <embeddedXMLContent> <alert xmlns=urn:oasis:names:tc:emergency:cap:1.1 xmlns:xsi=…> <!-- CAP payload with Tsunami bulletin embedded here--> </alert> </embeddedXMLContent> …

  • Reference Implementation• Messaging: o Asynchronous communication o Message Oriented Middleware (MOM) o Apache Active MQ• GUI Client o Command and Control User Interface (CCUI) o Eclipse Rich Client Platform (programming language: Java)• Encodings o XML Schema + Java XML Beans
  • Participation at IOWave 10/2011 in Jakarta
  • Conclusion• Simple and robust communication model o Follows UNESCO IOC/ICG guidelines o Accounts UN/ISDR recommendations o Based on open standards (OGC, OASIS) o Reference implementation • Open source MOM • Standard compliant (xml schema) • Tested/Validated at IOC exercise• Deployment is not a technological problem o Longsome decision processes on high levels (political processes) o Development of information systems not driven by IT experts
  • Outlook• TRIDEC: EU project focussing on TEWS in Mediterranean o Project partner: Turkey – system is running there o Cooperation with ICG/NEAMTWS o Evaluation which countries are interested to participate• Indonesia: Evaluation of the system with real data• Convince IOC/ICGs to rely on open standards (Cap, EDXL)• Long term: official IOC CAP profile for tsunami bulletins
