As expected in the Atacama Desert, Landsat doesn’t detect much vegetation—only some green along the Río Loa and next to the city of Calama. Calama has seen a rising population because of the influx of mine workers. The images show this visible urban area expansion. Notice the airport expansion that took place between the 2010 and 2016 images.
