Cartographic Animation

Cartographic animations are an important way of displaying results and falls with geovisualization.  Having a time series of information can inform the viewer of things that aren't necessarily apparent when looking from image to image without the assistance of an animation. Trends become distinct as we see images before and after a single frame. This can even allow us to make predictions and forecasts based off of previous behavior.
