EDIM Project Context

FOSS4G 2009 Sydney – SDI Components as
Building Blocks for Early Warning Systems

Earthquake Disaster Information System for the
Marmara Region, Turkey
Joint-Project: University of Karlsruhe (GPIK),
GeoForschungs-Zentrum Potsdam, HU Berlin,
lat/lon GmbH, Delphi IMM, KOERI Istanbul

Funding provided by BMBF/Geotechnologien

Funded from 2007-2010


Scope: SDI development with emphasis on sensor
data, fine grained user management and sustainable
spatial data infrastructure setup
Software development and conceptualisation
3 sub-projects:

FOSS4G 2009 Sydney – SDI Components as
Building Blocks for Early Warning Systems


In Part A, estimates of the degree of reliability will be
delivered, as well as real-time information of
earthquake source parameters and near-real-time
shakemaps for the region.
In Part B, an advanced sensor technology of selforganising networks will be developed and tested,
using Istanbul as an optimal geographical test site.
In Part C, data and information from A and B will be
connected by a dynamic geo-information infrastructure
and communicated with a user-oriented information and
visualisation strategy.
Motivation

Improve early warning information

Support rapid response

Provide decision support system components

Sensor Data in Project SDI
FOSS4G 2009 Sydney – SDI Components as
Building Blocks for Early Warning Systems


Sensor information

Seismic events (E-Z-N-values)

Interface for further (pluggable) sensor nets

Uniform access over SOS protocol
Alerting network based on SOSEWIN software

Triggers notification in case of seismic events

Notification contains information on seismic event
(time, location, seismic waves, etc.)

Propagation of events into Portal software
Publish-Subscribe Mechanism
FOSS4G 2009 Sydney – SDI Components as
Building Blocks for Early Warning Systems


Indirect network access through publish-subscribe
mechanism (SOAP communication)

Register portal component to message-notification
broker

Receive alerting messages asynchronously

Parse alerting message and extract user-specific
information
Bridges gap between portal software and real-time
alerting system
