  1. Virtual Disaster Viewer:Understanding Disasters through Shared Knowledge Ronald T. Eguchi Paul Amyx Charles K. Huyck ImageCat, Inc. DHS – S&T Workshop on Emergency Management: Incident, Resource, and Supply Chain Management 5-6, November 2009, UCI, Irvine, CA www.virtualdisasterviewer.com

  2. Presentation Outline • The Problem • VDV interface for damage assessment • Outreach • Future activities • Summary

  3. Problem Statement There is a post-disaster need… … for expert analysis to provide rapid and accurate commentary after significant events … to harness the skills of experts from a wide variety of industries, affiliations, and locations … for a central repository for experts’ interpretations to improve dissemination and discussion of data from current and past disasters • After major disasters, it is not always feasible to deploy field teams due to damage and/or access restrictions • Multiple field deployments can result in duplication of effort and costs • Data is not shared from multiple field teams

  4. 2008 Wenchuan, China Earthquake Beijing Korea Japan Wenchuan Earthquake Tibetan Plateau Shanghai Chengdu Philippines Hong Kong 2008 Wenchuan Earthquake Details (known): May 12, 2008, 2:28pm(Local time) Magnitude: 7.9 (USGS) Location: 30.986°N, 103.364°E Depth: 19km Fault length: approx. 250km Details (unknown): Number of ? dead (missing) ? injured ? buildings collapsed ? buildings damaged ? homeless ? evacuated ? people affected ? Economic loss Damage Estimates: 69,200 dead (20,000 missing) 374,200 injured 5.4 million buildings collapsed 21 million buildings damaged 5 million homeless 15 million evacuated 46 million people affected Economic loss US$80 billion? UNDMT Situation Report No. 8, 14 June 2008

  5. VDV Interface for Damage Assessment • The login procedure • Accepting an assignment • Scope of evaluation • The notion of a damage scale based on remote-sensed images • Damage assessment procedure • Results from 2008 Sichuan, China earthquake

  7. Grid Cells for Analysis

  8. Structural Failure

  9. Landslides & Blocked roads

  10. Remote Sensing for Earthquake Scale (RSE) Damage Scale Descriptions

  11. Pre Post Assigning Damage Level

  12. Results BUILDING DAMAGE

  13. Results LANDSLIDE EXTENT

  14. The VDV Community...so far • Initial funding from EPSRC (UK), EERI, MCEER (USA) • Tool developed by ImageCat • Currently being developed for inclusion in EEFIT missions to Indonesia & South Pacific • 84 expert volunteers from 8 countries

  15. VDV Outreach Conferences & Workshops Wired Magazine article: April 2009 Imaging Notes Magazine article: Fall 2009 Flagship project for Community Remote Sensing theme: IEEE International Geoscience & Remote Sensing Symposium (IGARSS) 2010

  16. Future VDV • Sumatra & Samoa currently being developed • Validation of expert analysis & assessing experts’ skills – “superusers” • Extend functionality may include • Video field blogs & text summaries of professional findings • Greater use of commenting facilities • Develop analytical tools for automatic interpretation of results

  17. Summary VDV developed to fill technological need for a post-disaster data portal Multiple functions developed according to needs of field teams on per-event basis Currently broadening VDV’s outreach for future funding and data partnerships A growing community of expert users and contributors are realizing VDV’s potential
