A bit late I know but I have just discovered the Wired Best Science Visualisations of 2009. There are a couple that use geographic data (of particular note is the California Earthquake simulation). The crucial advantage of animation in a scientific context is the ability to clearly show three dimensional information. This is never really adequately achieved in a single plot on a 2D surface. The videos set a high bar for those of us who enjoy animating complex research outcomes and are certainly inspiring.
