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.

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

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
