For this project, I do not think there is much new information to be uncovered by comparing the map of Missouri from the 1960s to the map used for Google Earth today. Some things that are interesting to compare are the changes in infrastructure in the form of highways and roads compared to how they were nearly 60 years ago. The interconnectedness of cities, both big and small, is on display when comparing these two maps. It is also interesting to see some new cities pop up on the more recent map. And to see some cities from the 1960s not being named anymore or being completely absorbed by larger cities or even changing counties.
The weakness in this approach to mapping changes historically is that a fair amount of information is missed. Just looking at the overlayed map makes for a game of “Where’s Waldo?”. Not all changes are directly explained, leading to a loss of information for the reader and them not understanding the actual changes that have taken place over the course of 60 years. A way to make this approach better would be to make the map more interactive and display all major changes in each county as the reader hovered over it. That way, changes are more evident, and information is not lost needlessly.
