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.
Motivation • Improve early warning information • Support rapid response • Provide decision support system components • Generate personalised visualisation for various stakeholders • Integrate sensor data • Use standardised software components • Use case: Marmara region
.org • joint project between AG GIS, Dept. of Geography, Uni Bonn and lat/lon • free software in terms of FSF: LGPL • .aim • interoperability • management of geospatial data • setup of spatial data infrastructure (SDI) • .how • ISO-models and OGC-interfaces • abstraction from data sources • Java programming language / JEE web application • .now • most comprehensive implementation of OGC/ISO-standards in free software: • WMS & WCS (OGC reference implementations), WFS, CSW, WPS, 3D, SWE, etc. http://www.deegree.org/
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
Publish-Subscribe Mechanism • 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
Interoperability – the technical details • SOS: OGC certified • Integration of external data: • historical seismic events • real-time access to on-site sensors in Istanbul
Pre-EDIM Situation • Access to standardised interfaces and data services • Problem statement: • No integration of sensor data • No user-specific visualisation • No means for EWS
Phase I – Integration of Security Layer • Security Layer as basis for personalisation • Proxy ensures standards-compliancy • User management based on services and database • Fine grained (spatial) definition of rights and roles
Phase II – Integration of Sensor Data • Integration of sensor data Sensor Observation Service (SOS) • Integration of Early Warning Messages (SOSEWIN network) • Visualisation of sensor data (e.g. by charts)
Visualisation of Sensor Data • Statistics based on sensor stations • Charts (e.g. for time series) • Raw data
Phase 3 – Integration of Monitoring • Ensures operation of all critical services • Notifies administrator about service malfunction • Planned: Data & service backup through grid computing
owsWatch – The SDI Service Monitor • Monitors OGC web services • Illustrates service response times • Triggers alerts in case of service malfunction (e.g. email, SMS, etc.) • Only accessible by authorised users
Final Infrastructure – Challenges met • Integration of SOSEWIN access (through web service encapsulation) • Integration of sensor data (through deegree SOS Service & Client) • Integration of user specific rights management • Integration of service monitoring
iGeoPortal – Access to the EDIM-Infrastructure • Personalised access to geoinformation • Individually configured for diverging user requirements (e.g. decision makers, administrators, etc.)
