An amazing new platform that has come out recently is Google Timelapse which allows users to see what urban growth and sprawl has looked like between 1984 and the present. When you visit the site, you can search for various locations or see the suggested places at the bottom, and zoom in and out as needed.
The key use for this tool is to monitor change over time. The most disturbing searches for me were not urban sprawl on the city fringe but deforestation in Brazil and Borneo. Great for any social studies, science, history, well, ANY teacher! Perhaps even our elected leaders?
