Architecture of the RSHDSS

The SDSS architecture must facilitate the detection of a failing hazardous waste site and provide useful recommendations for emergency response and recovery. The first two years of the project focus primarily on the first two components of the remote sensing-assisted hazardous waste site SDSS – monitoring and emergency response. The Monitoring system research focuses on a) identifying the optimum variables to be in the database, and b) how to effectively monitor these variables to detect hazardous waste site compromise. The Emergency Response system research focuses on formulating the appropriate questions and developing software that responds to an emergency situation recognized by the monitoring system. When a failure is identified, information will be passed to the analytical system and a series of pre-programmed scenarios will be tested. The analytical system will provide specific calculations about

  • potential exposure to hazardous materials, and

  • response alternatives that will protect the most humans, flora, and/or fauna.

It will also specify and request additional data (e.g., remote sensor data) be collected to improve decision making. This will cause our SDSS to interface with Dr. Hodgson’s Remote Sensing Hazard Guidance System SDSS. The nature of the information and the questions that must be considered to address specific management decisions will dictate the final architecture of the hazardous waste site SDSS. Well-conceived management questions and quality information are only of value when the SDSS can identify the optimum monitoring and management strategy. Significant effort is going into the design and testing of the hazardous waste site SDSS architecture.

    Modules for the RSHDSS

All modules are under development in the ArcGIS 9.0 VBA environment. In other to use the modules, ArcGIS 9.0 with SP3 or ArcGIS 9.1 should be installed. The alpha version of the monitoring subsustem modules is now available. Please login to download the modules.
