Informal Settlements
A challenge for the emerging economy
Development are characterised by:
Rapid Changes, (Expansion and contraction)
Unstructured
Unplanned
Introduction

Floods in Africa
SA 927, 710 people affected since October 2007
The effects go beyond death and extend to quality of life
Introduction

Flood Preparedness
Detect Informal Settlements
Acquire 50/100 year flood lines
“Continuous” analyses to raise an alert when they coincide with flood lines
Floods Preparedness

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

The Sensor Web

The Use Cases Requirements

Non-Functional Requirements
The system should be open
Provide open access to data
Standards such as OGC
The system should be web based
Increased system accessibility
The system should be adaptive
Respond to changes in environment
Requirements

Architecture
Data View
Flood Lines
Informal Settlements
Services View
Informal Settlement SOS, SPS
Flood-lines SOS
Risk SOS and SAS
Architecture

GEOSS The System of Systems Approach Where a system is a collection of components Architecture

Continued Research
Implementation in progress
Mechanism to automatically and continuously arrive at flood-lines using DEM and GRID
Attaining community buy in – untrusted technologies
