Compare the building footprint of cities seen at the same scale
Compare the building footprints of two locations on Earth seen at the same scale. Buildings are an indicator of transportation activity as most trips involve going from one building to another (example: home to work). By viewing what cities look like from a given distance above, we can get an idea of the transportation activity in the city. We can also get an idea of the size of the city, its density, and economic activity.
