Flood Photo Viewer - interactive map 
Note: this link will open a new browser window
Oblique photos have been taken by aircraft during many flood events dating back to 1946. The photos and their geographic locations can be viewed in an interactive web based mapping system (iMap).
How to use: zoom in to your area of interest. In the layers list, click "Flooding info" and click the flood photos layer to display point symbols on the map where flood photos are centered. Click on a point symbol for flood photos and data.
