One of my students, Karl Gustafson, used an interesting combination of geospatial and political data to create a video (see below) that examines some historic cases of gerrymandering in Pennsylvania. He used this as background for looking into what appears to be some pretty clear cases of gerrymandering in the making.
While the production quality on the video is none too slick, Karl does a good job of using a series of overlays, a clear, direct script and the features of Google Earth to explain what gerrymandering is and how it has been used ion the past and how it is currently being used to literally re-shape Pennsylvania politics.
You can see Karl's evaluation of the methods and processes he used here.
Very interesting conclusions. I like the use of Google Earth to demonstrate the changes.
