Transcript

  • 1. How Geoscience Australia ProvidesInformation on Natural Disasters Andy BarnicoatGA information on natural disasters
  • 2. Geoscience AustraliaDepartment of Resources, Energyand Tourism • 760 staff • Canberra, Alice Springs & PerthProvides technical information andadvice to Government • Operational science • Geography and GeologyHas a role in emergency response • Earthquakes, Tsunamis • Sentinel bushfire hotspots GA information on natural disasters
  • 3. Sensor networks • National Geophysical Network • National Geomagnetic Network • National Gravity Network • Australian Regional GNSS NetworkGA information on natural disasters
  • 4. Sensor networks in emergency responseAustralian NationalSeismic Network (192stations) – Supports Joint Australian Tsunami Warning System in partnership with BoMGA information on natural disasters
  • 5. Sensor networks in emergency responseSatellite remote sensing…GA information on natural disasters
  • 6. Satellite’s in Emergency ResponseTask Acquire Analyse Deliver GA ground stations OGRE procurement panel Generate GIS FTP site compatible image Email GA Sentinel AsiaTasking Automated Footprint Physical media International Charter Extraction for Space and Website Major Disasters Map productionGA information on natural disasters
  • 7. RockhamptonRaw Radarsat-2image GA information on natural disasters
  • 8. RockhamptonFlood polygon GA information on natural disasters
  • 9. Processing chain 1. Raw satellite image 2. Flood extraction 3. Map ProductionGA information on natural disasters
  • 10. GA information on natural disasters
  • 11. GA information on natural disasters
  • 12. Queensland:15/10/2009vs.06/01/2011MODIS imagery GA information on natural disasters
  • 13. Condamine – Balonne RiversGA information on natural disasters
  • 14. Flood Mapping SystemGA information on natural disasters
  • 15. GA satellite imagery response summary • 609 images captured • 109 products generated • 2616 products downloaded • Data volumes: – Each image was approximately 1 GB • 609 GB download required in near real time – Each product was approximately 50 Mb • 130 GB upload required in near real time • This seriously tested current (relatively traditional) delivery technologiesGA information on natural disasters
  • 16. Sensor network in emergency response • Human sensors – Felt reports (post event data)GA information on natural disasters
  • 17. Sensor networks – Social media • Social media as a sensor network • U.S. Geological Survey: Twitter Earthquake Detector • Crowd 2 Agency (C2A) • Social epicentreGA information on natural disasters
  • 18. Agency 2 Crowd• Traditional web delivery interface• Capacity issues with near real time delivery • e.g. Victorian bush fires 2009• Presents a view • Web services will allow integration into end-user applicationsGA information on natural disasters
  • 19. Agency 2 Crowd (A2C) issues • Data volumes are increasing rapidly – Spatial & spectral resolution both increasing Volume of worldwide climate data is expanding rapidly, creating challenges for both physical archiving and sharing, as well as for ease of access and finding what’s neededOverpeck, J.T., Meehl, G.A., Bony, Easterling,D.R., 2011: Science 331,700 -702. http://www.sciencemag.org/content/331/6018/700.full.html GA information on natural disasters
  • 20. Agency 2 Crowd • Cloud computing assists with: – Storage capacity – Computation capacity – Delivery speed – Increased reliability – Surge capacity • But… at the petascale traditional databases breakGA information on natural disasters
  • 21. Improving Data Assimilation:a National Location ‘Scaffold’ (or Framework) Multi-scale Nationally Standardised Grid Framework (CRC-SI Demonstrator)• current, consistent, authoritative grid-cell data repository• multi-scale data management and governance environment• facilitate and improve data access and sharing• Lockheed Martin, VPAC, NCI, GA awarded $3.4 million to develop an infrastructure to ‘Unlock the Landsat Archive’ GA information on natural disasters
  • 22. Final Remarks • To a geoscience agency social media is just another sensor network • In the future we will need more data about data (metadata) than ever before • Data volumes in 2020 will require new architectureGA information on natural disasters
  • 23. Questions?GA information on natural disasters
