There’s no doubt that there’s many awesome uses of ArcGIS Online. There’s been efforts to map and track hurricanes, display cleanup efforts from areas ravaged by storms.
Mapping sporting events; social media and news maps from events around the World and now you can view a TON of imagery captured and shared by NASA from the International Space Station (ISS).
Using this awesome map users can pan around the World and click on ISS icons as they pass over almost any place on Earth. Click the icon and see the amazing photograph captured by a NASA astronaut on board the ISS. You’ll also see meta-data including astronaut Twitter @handle, a brief description of the photo, and a link to a high res image… simply awesome!
