Google Earth is one of my favorite tools to use in history and geography lessons. Google Earth enables students to see and explore places in ways that printed maps and images never could. One of the features of Google Earth that I love to use in history lessons is the image overlay function.

Image overlays in Google Earth let students make comparisons of historical maps with current maps. Image overlays can also be used to overlay different map types on top of the default Google Earth imagery.
