  1. Using the Grid to aid Humanitarian Relief Efforts Sean Moran Cambridge University sean.moran@cern.ch

  2. Agenda • Origin • Unosat Overview • Indian Ocean Tsunami • Unosat and CERN • Unosat and the Grid • Future Roadmap Sean Moran

  3. Unosat Origin • Pre-Unosat Environment • Difficult to access reliable Geoinformation • Satellite imagery expensive and complex • The Digital Divide • Birth of UNOSAT • Concept was first devised in 2000 • Green light for the project came in 2002 • Operated by UNOPS Sean Moran

  4. Unosat Overview • Satellite imagery based web mapping service • Objectives • Easy access to quality geoinformation services • Organize the demand for geoinformation • Ensure cost-effective and timely products • Core Services • Humanitarian Mapping • Image Processing VEGETATION - 1 Km IKONOS - 1 m Sean Moran

  5. Unosat System i j k Ground station l Data suppliers USER WWW UNOSAT Central Unit m

  6. Relief Projects • Case Study: Indian Ocean Tsunami Relief and Development • 29th Dec 2004: First Map distributed online to field users • 14th Jan 2005: Imagery Bank online: • 100 Tsunami-related maps (pre and post) • 670 raw satellite images • January: 200,000 tsunami maps downloaded in total Sean Moran

  7. Unosat and CERN • Partnership since 2002: “CERN is the initiator of the web and because of the nature of the project (which is internet based), we approached CERN," - Alain Retiere, UNOSAT Director • Excellent network, computer infrastructure and support • Asian Tsunami Example: • Central Web Services at CERN under considerable strain • Solution quickly found by CERN's Internet Services Group • Result: UNOSAT data remained available continuously Sean Moran

  8. Unosat and the Grid • Potential Bottlenecks: • Limited capacity & processing power • Multiple Satellites being launched • Surveillance drones** • Solution: The Grid? • Data intensity: Excellent test case • Openlab Project: • Proof of Concept • Asses upload, download and compression • Provide roadmap for future implementation **See BBC News Online: “Eternal planes' to watch over us” August 2005

  9. Impossible to work on GRID without these! lcg-cr command Openlab Project • Pre-development • UNOSAT Virtual Organization (VO) • Negotiate 3.5TB in CASTOR • Collaboration with ARDA group • Image Upload • Bring files to a User Interface (UI) (e.g. EIS testbed: lxb0709.cern.ch) • Register Images on LFC • Copy Images to Storage Element (SE) (e.g. CASTOR) Sean Moran

  11. Compression • Image Compression • JPEG2000, ECW Mode • Speed up compression of maps • Facilitate image distribution • Realistic Scenario:Matagalpa Flood Map

  12. Future Roadmap • Openlab project: proof that Grid meets the needs of Unosat • Future objectives: • Expand framework into a fully-fledged application (Website Integration) • Provide widescale access to relief community • LCG & CERN IT: Negotiate resources with sites to provide resources “At the moment, the maps are only constrained by the imagination of the users - and the possibilities are infinite.” - Alain Retiere, UNOSAT Director Sean Moran
