For this week, we made a temporal map detailing the change in population over time for the largest cities in the United States. This map also shows how the overall population center of the U.S. has shifted from the East Coast towards the middle of the Contiguous states.
To make a temporal map, you need to have data that has some sort of date element to it, such as days, years, months, etc. The next step is to enable time capability with your data. After that, you can incorporate the built in Time Slider from ArcMap to have your data cycle through as time increases.
For my map, there was also the incorporation of visual elements such as a moving indicator that went along a time scale to indicate at which point in time the map was being shown. There are also dynamic text elements that help indicate the time.
This type of map making can be very helpful to show trends. Scientiests can use them to display their research into the way things such as diseases, invasive species, pollution, etc. spread over a geographic area over time.
