This is an example of cartographic animation.  In this image; the stages of flooding are shown as the waters continue to rise for the Tar River basin in North Carolina.  Cartographic animation is typically taken from historical data and is not an exact science but can be a useful tool when planning for natural or man-made disasters.  The data used to create this animated map is from September 1999.
