Explore a global timelapse of our planet, constructed from Landsat satellite imagery. The Columbia Glacier is retreating at a rapid rate. Each frame of the timelapse map is constructed from a year of Landsat satellite data, constituting an annual 1.7-terapixel snapshot of the Earth at 30-meter resolution. The Landsat program, managed by the USGS, has been acquiring images of the Earth’s surface since 1972. Landsat provides critical scientific information about our changing planet.
