Why we need Historical Disaster Data?
Global distribution of natural disastersGlobal distribution of natural disasters
Climate Change is the mixed and interactive result of earth evaluation and human activities.Natural Disaster is getting much more serious from such interactivities.

Scientific Data and Disaster Mitigation
The mitigation activities from scientific society PredictionMonitoringRe-Construction
Well-using of Scientific Data is very important for disaster reductionsEarth Observation DataIn-situ DataThematic DataBackground DataSocial-economic Data
The Gap of Data using in Disaster Mitigation
Capacity of satellite observationorbit, sensor, weather condition…..
Capacity of real-time processingDisaster thematic modelFast detection softwareSupporting from Supercomputers
Capacity of data infrastructureDistributed data providersComplicated searching and accessing

Data Using Analyses of Wenchuan Earthquake Disaster (12 May, 2008)
The duration of high frequent data using in Wenchuan case is only three weeks
Case 1：Wenchuan Earthquake
Case 2 ： World Flood Monitoring Grid

World Flood Monitoring Grid
HDDG as an e-infrastructureTargets of Historical Disaster Data Grid
To archive the scientific data of each disaster (above certain level)
To bridge disaster event with international EO data infrastructures
To make easy accessing of assistant EO data from volunteer space agencies
To collect and provide the necessary background data and disaster evaluation data
To keep and promote the data democracy around the world
To make it possible for disaster suffering country and region to generate thematic disaster information by themselves
Data on certain disaster event shouldbe captured
(ordering, imaging, receiving and preprocessing)be provided
(authorization, publishing and transfer)be stored
(save to disks and databases, temporary storage)be managed
(metadata generating, re-formatting, registration)be archived
(operational and long term storage)be reused
(scientific study and comparative using)

Questions to be thought
Data Policyfrom observation data providerfrom thematic information providerfrom data covered country
Cooperate with world-level activitiesInternational Charter, UN-SPIDER, ICSU/IRDRto connect with and response to the disaster call
Collaboration with operational Data Systemtechnical approach (NG-SDI)
Long term operation mechanism
Suggested Cooperation Opportunities
To contribute the DCP (data collection point) for Asia and North AmericanDCP@Asia
CAS (CNIC&CEODE) has decided to provide 100TB on-line space
DCP@NAWho will be the hoster?
To collaborate on the developing of the virtual SDI components
A prototype is scheduled to be presented by CAS(CEODE&CNIC) to UN-SPIDER and ICSU/IRDR this November (GEOSS summit @ Beijing).
Similar prototype study is desired to be taken by US partner.Joint team to work together
