Creation of a Spatial Decision Support System as a Risk Assessment Tool Based on Kentucky Tornado Climatology
… making the storms challenging to forecast. Using geographical information systems (GIS), a web-based spatial decision support system (SDSS) was created to help understand the spatial dimension of tornado risk assessment. The risk values are calculated using Tornado Days rather than taking a crude …
