A challenge for the emerging economy

8. Development are characterised by:

Rapid Changes, (Expansion and contraction)

9. Unstructured 10. Unplanned Introduction 11. Floods in Africa

SA 927, 710 people affected since October 2007

12. The effects go beyond death and extend to quality of life Introduction 13. Flood Preparedness

Detect Informal Settlements

14. Acquire 50/100 year flood lines 15. Continuous analyses to raise an alert when they coincide with flood lines Floods Preparedness 16. The Sensor Web An open complex adaptive system organised as a network of open sensor resources, which pervades the internet and provides external access to sensor resources. By open sensor resources, we include any open system, including sensor networks that are a source of sensor data or sensor meta-data (van Zyl, Simonis, and Mcferren, 2008). The Sensor Web 17. The Sensor Web 18. The Use Cases Requirements 19. Non-Functional Requirements

The system should be open

Provide open access to data

20. Standards such as OGC The system should be web based

Increased systemaccessibility

The system should be adaptive

Respond to changes in environment

Requirements 21. Architecture

Data View

Flood Lines

22. Informal Settlements Services View

Informal Settlement SOS, SPS

23. Flood-lines SOS 24. Risk SOS and SAS Architecture 25. GEOSS The System of Systems Approach Where a system is a collection of components Architecture 26. Continued Research

Implementation in progress

27. Mechanism to automatically and continuously arrive at flood-lines using DEM and GRID 28. Attaining community buy in untrusted technologies Continued Research 29. Thank-You Questions? Please email me. [email_address]
