With the US presidential election taking place today, it is a good time to learn more about the past presidents of the United States. We came across this page by Google, showcasing the Google Earth API. However, as the Google Earth API no-longer works in most browsers, it is better to explore it in Google Earth using the KML files provided.
For your convenience we have put all the KML files into a single file that you can download here. We also fixed a few KML errors in the file so that the timeline feature works properly. You can click on the ‘play’ symbol in the time toolbar to see the progression of new states being added to the union over time.
