In essence, Worldview shows the entire Earth as it looks "right now" - or at least as it has looked within the past few hours. Worldview supports time-critical application areas such as wildfire management, air quality measurements, and weather forecasting.
The imagery is generally available within three hours of observation and can easily be compared to observations from the past - just click or drag the time sliders at the bottom of the page. Imagery is available from May 2012 onward and we are working to provide access to earlier dates. Arctic and Antarctic polar stereographic views of several products are also available for a "full globe" perspective.
Data granules, used to create the imagery are also searchable and can be downloaded through the Worldview interface.
Browsing on tablet devices (iPad 2+ recommended) is currently supported for mobile access to this spacecraft imagery while in the field or on the couch. Please note, however, that this is an alpha (preview) release and many features are still under development. Comments/suggestions/problem reports are welcome via Earthdata support.

On the backend, Worldview is supported by the Global Imagery Browse Services (GIBS) – a new set of standard services provided by EOSDIS to deliver global, full-resolution satellite imagery in a highly responsive manner. GIBS enable interactive exploration of NASA's Earth imagery for a broad range of users. GIBS serve the imagery to any internet-enabled client.
