Case Studies: Our KML layers include 120 sites around the world where we have researched and studied environmental changes. For each site (geographic point), the KML includes the story associated with the environmental change, thumbnail images of the imagery, and links to our web site. The KML also includes links to the actual imagery that can be overlaid and compared in Google Earth. We used a combination of KML files to develop a system that allows our users to visualize the 120 sites in our Atlas and research general information about each site. We then provide a secondary level of KML files that allows the users to overlay the imagery on top of the Google Earth base layer to visualize the environmental change that we have described.
