Visualizing the Human Imprint

One of the most valuable tools in GIS is the ability to overlay two images of the same location and then compare before and after images. ESRI has a website that allows the user to go back and forth between Landsat Satellite images using a simple slider bar. You can see the dramatic transformation of the earth at places like the Aral Sea and the Athabaska Oil Sands in Alberta. Here is a link to the site.
