This web-based app from NASA's Earth Observing System Data and Information System (EOSDIS) gives users the power to interactively browse over 800 global, full-resolution satellite imagery layers and download the underlying data. Many of the available imagery layers are updated within three hours of observation, essentially showing the entire Earth as it looks "right now." Arctic and Antarctic views of many products are also available for a "full globe" perspective.
Worldview supports time-critical application areas, such as wildfire management and flood monitoring, through a comprehensive set of layers related to air quality, ash plumes, drought, dust, fires, floods, severe storms, smoke, water/ice, settlements, vegetation, and temperature.
Browsing on tablet and smartphone devices is generally supported for mobile access to the imagery.
