Day: April 30, 2014

Two Washington D.C.-based events this month helped introduce Landsat to the public. On April 21 and 22, at an Earth Day celebration in D.C.’s Union Station, visitors explored changes to Earth’s landscapes over time. Using cubes displaying four different Landsat scenes, participants puzzled out the sequence of large landscape changes in Brazil’s tropical forests, the Mount St. Helens region pre- and post-eruption, Yellowstone National Park before and after the widespread 1988 fires, and Las Vegas over the last four decades of extensive urban growth.
