12.5.3. Decision Support System Geospatial database plays a major role in the flood
management since it provides timely inputs meeting the user needs in terms of information content, format and multiple thematic layers integration and analysis. For this, a related Geo-spatial data with proper data standards formats and data access mechanism is essential. To
achieve flood preparedness, mitigation, relief and rescue, Decision Support Systems (DSS) are effective tools for decision-making using available geospatial data sets in centralized data server. DSS is an intelligent information system for flood management and relief. It will be evolved through participation of knowledge institutions at user end using spatial datasets.
