How Datasets Are Used in DSS-WISE Web
Flood Simulation
Elevation data provides the terrain model for water flow calculations, while land cover data determines surface roughness and flow resistance.
Risk Assessment
Levee and infrastructure data help identify critical assets at risk and model potential failure scenarios.
Visualization
All datasets are integrated into interactive maps for comprehensive flood impact visualization and analysis.
Data Quality & Standards
All datasets used in DSS-WISE Web are sourced from authoritative government agencies and maintained according to established standards. Data quality varies by source and region, and users should verify critical information before making decisions based on simulation results.
