Las Vegas Growth — 1984 to 2012
Google's Time Lapse project is giving Internet users around the world a rare perspective on how certain areas have changed over time.
This 20 year timelapse, which spans 1984 to 2012, shows how Las Vegas has expanded over time. Note that as the strip grows, Lake Mead (at right) shrinks.
Each frame of the timelapse map is constructed from a year of Landsat satellite data, constituting annual 1.7-terapixel snapshot of the Earth at 30-meter resolution.
