WMS:Flood Impact Map
The floodplain delineation tools allow you to compare two different flooding scenarios and generate a flood impact coverage. A flood impact coverage shows increase and decrease in flooding from two different delineations using different classifications. Like other coverages, this can also be exported from WMS for reporting or other flood management purposes.
An impact map is created (Conversion | Flood→Impact Map command in the Flood menu) by showing classified increases and decreases between two separate delineations. You can specify what the increments in change are for increased and decreased (up to 5 each) flooding between two calculated datasets. A coverage of polygons is then generated for each classification. A keyword or text string can be stored with each polygon classification in order to better identify it when exported to a shape file for use in Geographic Information Systems (GIS) analysis.
