3. The Decision Support System (DSS)
The DSS
performs sensor and information fusion
generates situation awareness („common operational picture“)
generates regionalized decision proposals
what warn level in what part of the coastline?
when to warn? (wait for further sensor input?)
supports message generation and dissemination
by
aggregating all incoming sensor information
interacting with simulation and modelling systems
accessing huge databases
(geodata, risk modelling, vulnerability assessment, ...)
connecting to available dissemination systems

4. Warning Segments and Warning Levels

5. Core Decision Support Loop
DSS is designed for decision
making under uncertainty and
time pressure under
operational 24/7 conditions
Main DSS Tasks
Aggregate all available information
(information / sensor fusion)
Generate, update and visualize
Situation Awareness
Generate, update and visualize
Decision Proposals
Generate Products on request
and initiate their dissemination

6. Information Fusion / Sensor Fusion
Live Sensor Observations (processed by the resp. Sensor Systems)
Real-time Data
ad-hoc Information
pre-compiled Databases
Simulation System
a-priori Information
Tsunami Scenario Risk- & Vulnerability Geospatial
Repository Modelling Data Repository
Large database of pre- Based on tsunami scenarios Geo and Sensor Data
computed scenarios Infrastructure G(S)DI
US DOD Joint Directors of Laboratories Data Fusion Group (JDL) Data Fusion Model (Revised)

8. Integration of Risk & Vulnerability Information
Results of Risk Modeling
and Vulnerability Analysis
are integrated into DSS
DSS user can access
information at any time
In case of tsunami threat,
specific case-dependent
information is displayed
Data per warning segment
(current status):
Exposed People
Critical Facilities
High Risk Facilities
Risk Index

9. DSS Product Generation and Dissemination Process
DSS can generate targeted products (messages)
regionalized (with specific information for the individual area)
target group specific (public, media, government, NTWCs, ...)
Different product types in different versions
Text messages (short/long), Reports, Maps, ...
plain text, image, PDF, <?xml version="1.0" encoding="utf-8" ?>

11. GITEWS Decision Support System: Status and Outlook
Central Component for Tsunami Early Warning Systems to
provide situational awareness
generate decision proposals
automate targeted product (message) generation
Future Extensions for
additional hazard types (multi hazard approach)
additional sensor systems
integrated data, geodata and sensor infrastructure
additional analysis and processing functionality
Support for interoperability and reusability (use of open standards)
applicable in all phases of the Disaster Management Cycle
can be applied in a distributed / networked context (e.g. networked DSS)
