Google's Landsat Viewer

Google's Landsat Annual Timelapse viewer is an interactive video that allows user to pan and zoom anywhere on Earth and view annual mosaics from 1984 to the present at the resolution of a Landsat pixel. Users can create custom views of their own areas of interest by zooming and panning to a particular view, and then clicking the "Share this view" button, which produces a custom URL that you can send to anyone. Alternatively, a user can construct URLs by inserting the appropriate latitude, longitude, and zoom level.
