Case 1: Overlay - Data and Results
Data on Coastal Hazards (risk and vulnerability of human communities) are combined with data on Biodiversity (coastal wetlands). These data or maps are overlaid through GIS to identify where there are wetlands closest to the human communities most at risk and vulnerable to coastal hazards. The overlay or GIS Intersection of these data sets indicates wetlands that may have some of the highest value for mitigating coastal hazards.
