Situation awareness in web-based environmental monitoring systems

The Tasmanian ICT of CSIRO developed a Sensor Web test-bed system for the Australian water domain in south-east of Tasmania. This system provides an open platform to access and integrate near real time water information from distributed sensor networks. Traditional hydrological models can be adopted to analyse the data on the Sensor Web system. However, the requirements on high data quality and high level domain knowledge may greatly limit the application of these models. To overcome some these limitations, this project proposes a data mining approach to analyse patterns and relationships among different hydrological events. This approach provides a flexible way to make use of data on the Hydrological Sensor Web. To make data mining rules easy to understand, this project developed the user friendly interface demo to visualize the data mining rules and describe the application of sorts of rules.
