CE S Disaster Management Support Group  Work with WGISS task teams, e.g. IDN, WWW, Data Services  Work with WGISS strategy – WGISS Meeting & CSIRO Workshop in May  Provide info to WGISS/Task Teams before April

  Approach--DMSG define requirements & pass on to WGISS ; ; WGISS can better understand scope of our problem ; ; Different from current WGISS scenarios (“use cases”)?   Some differences (my preliminary perception) ; ; Many DMSG “use cases” high level, poorly defined ; ; Often users doesn’t know what they need ; ; Requirements are diverse ; ; Requirements are often specialized ; ; Users speak a different language DMSG requirements very different, I believe!! Opportunity & challenge for WGISS & DMSG

Hazard Team Recommendations Some Recurring Themes Integrated satellite/in-situ data sets - Models - Models - GIS/SDI - GIS/SDI Improved communications--networks Compelling demonstrations--fire,flood,…. Global data bases--accreditation/standardization - E.g. DEM (~1m vertical resolution) - E.g. DEM (~1m vertical resolution) Global systems
