Introduction
Google Earth is a fascinating tool that allows us to explore the world from the comfort of our homes. With its vast database of satellite imagery, we can see everything from the highest peak in the world to the most remote island in the ocean. But did you know that Google Earth also has a collection of historical maps?
What Are Historical Maps?
Historical maps are maps that show how an area looked in the past. They can give us insights into the development of a city or country, the changes in land use, and the growth of populations. Many historical maps are hand-drawn and are therefore unique pieces of art.
How to Find Historical Maps on Google Earth
There are two ways to find historical maps on Google Earth. The first is to use the timeline feature, which allows you to go back in time and see how an area looked in the past. The second is to use the overlays feature, which allows you to superimpose historical maps onto the current satellite imagery.
Using the Timeline Feature
To use the timeline feature, simply open Google Earth and look for the "Time" slider in the top-left corner of the screen. Move the slider to the left to go back in time. You will see the satellite imagery change to reflect the time period you have selected. You can also use the "Historical Imagery" button to toggle between the current and historical satellite imagery.
Using the Overlays Feature
To use the overlays feature, first, you need to find a historical map that you want to use. There are several websites that offer free historical maps, such as the David Rumsey Map Collection. Once you have found a map, save it to your computer. Next, open Google Earth and go to "File"> "Open." Select the historical map file and it will be overlaid onto the current satellite imagery. You can adjust the transparency of the overlay to make it easier to see the current satellite imagery underneath.
Why Use Historical Maps on Google Earth?
Historical maps can be useful for a variety of reasons. They can help us understand how an area has changed over time, which can be useful for urban planning and conservation efforts. They can also be used for genealogy research, as they can show where our ancestors lived and worked. And, of course, they can simply be fascinating to look at!
Conclusion
Google Earth's collection of historical maps is a treasure trove of information and art. Whether you are a historian, a genealogist, or just someone who loves to explore the world, these maps can be a valuable resource. So next time you open Google Earth, take a few minutes to explore the past!
