            "description": "The city of Las Vegas—meaning the meadows—was established in 1905. Its grassy meadows and artesian springs attracted settlers traveling across the arid Desert Southwest in the early 1800s. In the 1930s, gambling became legalized and construction of the Hoover Dam began, resulting in the city's first growth spurt. Since then, Las Vegas has not stopped growing. Population has reached nearly two million over the past decade, becoming one of the fastest growing metropolitan areas in the world. These false-color images show the rapid urbanization of Las Vegas between 1972 and 2018. The city streets and other impervious surfaces appear gray, while irrigated vegetation appears red. Over the years, the expansion of irrigated vegetation (e.g., lawns and golf courses) has stretched the city’s desert bounds. || ",

            "description": "Landsat is a critical and invaluable tool for characterizing the landscape and mapping it over time. Landsat data provides a baseline of observations for science about how human activities on the land affect water quality, affect wildlife habitat, affect air quality. The satellite imagery covers the entire 64,000 square miles of the Chesapeake Bay watershed (spanning six states and the District of Columbia). Without it we wouldn't be able to really understand how sources of nutrients and sediment have changed and where they are in the Chesapeake Bay. The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. The narration in this video is by Peter Claggett, a research geographer with the U.S. Geological Survey's Eastern Geographic Science Center. He has worked at the Chesapeake Bay Program Office since 2002, where he leads the Land Data Team that conducts research on land change characterization, analysis, and modeling in the Chesapeake Bay Watershed. The audio was adapted from a radio interview with EarthSky.org. || ",

The city and its surrounding area currently hold spots on the U.S. Census Bureau's top ten lists of cities and counties, ranking sixth and fourth, respectively. As Phoenix evolved from an agricultural to industrial economy, farmland was pushed to the outskirts in order to make way for suburban developments that stretched southeast and northwest of the city. Between 1974 and 2007, nearly 250,000 acres of agricultural fields were lost. During the same period a fourfold increase in residents brought the region's population to just below the 4 million mark. Witness the transformation of Phoenix in the time-lapse video of false color images captured by USGS-NASA Landsat satellites between 1972 and 2011. || ",

            "description": "The constant influx of residents to Las Vegas since the 1970s has made it one of the fastest-growing metropolitan areas in the world. Currently more than 2 million people live in the 600-square-mile desert region, centered around the world-famous Las Vegas Strip and its luxury resorts and casinos. No doubt, the steady commercial and residential development over the last 40 years has been a boon to the valley's economy, but dense urbanization has exacted a high price on its most vital natural resource: water. Abundant parks, golf courses and manicured landscapes in Las Vegas' arid climate require more water to maintain than they naturally receive. This has placed an unsustainable demand on the region's primary water supply—Lake Mead—where water levels have fallen in the past decade due to persistent drought experienced across the Southwest. Scientists predict drought frequency and intensity for the region will only increase as global temperatures rise. In the collection of false-color, time-lapse images below captured by USGS-NASA Landsat satellites, witness Las Vegas' explosive growth from 1972 to 2010. || ",
