EDIM Project Context 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: 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 self-organising 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.

Sensor Data in Project SDI 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
