The Water Quality Emergency Monitoring System Based on GIS and RS for Urban Drinking Water Source

With more and more serious problem on water pollution, it is significant to monitor the water quality and get to know the trend of the water quality change for water source management and water environment protection. Urban drinking water source quality monitoring system is based on GIS and remote sensing technology. This relatively integrated system comprises water source quality information receiving and collection and emergency response. By the integration of database and model-base, the system can receive and collect up-to-data information about flood from RS monitoring and routine observation. In application of image processing and information amalgamation, the change of water source quality can be rapidly confirm spatially and temporally, which can provide scientific methods to experts for them to manage and make corresponding policy.
