So NASA operates Global Hawk Drones domestically at 60,000 ft to study hurricanes, wildfires, and ozone-depleting molecules, all while collecting high resolution video of ground-based activity and also streaming it in real-time to government facilities to provide situational awareness.


Can't wait for this to hit Facebook...

The recent drone sighting in NYC has elevated awareness of this issue.  But it's not as if we didn't know our government has these capabilities.

I kept hearing about these capabilities, and by implication their applications, from the makers of very high-performance audio and video processing hardware used by "the government." Every time I'd ask about the apps for a new product, company spokespeople would say things like "unnamed government agencies," which I eventually learned meant the NSA as well as the military. It's important to remember that "the government" is not monolithic, consists of multiple agencies, and is staffed by multiple people, many of whom (agencies and individuals) have no idea what the others are doing.

Al, would the video compression technology have applications outside the world of weather and drones? For example, security or other camera-based applications?

I read that global warming might be the cause of the southern drifting cold air. I hope MASA's effort prove it right, and the world left in shock. Hopefully enough to be a catalyst towards change.

Cabe, can you clarify that sentence? Are you saying that global warming might be caused by "a southern drifting cold air", or the opposite? What is "a southern drifting cold air" and where is it on the globe?

I mean, the reason it is staying so cold in the USA at least far into spring might be cause by the warming of the north. Which in turn has changed the gulf stream and pushed the colder northern air farther south. As some people speculate.

Thanks for the clarification. That's an interesting theory. Is it put forth by climatologists?

This type of signal processing technology is commonly used in several different vendors' COTS or semi-custom boards and subsystems, for military and NSA-style security apps. The high-powered stuff is, of course, especially pricey.

Chuck, The underlying video appliance technology can be used by any number of applications, and can be deployed as an embedded system or operate standalone.  It combines advanced video processing with networking using COTS technology, so there are lots of potential apps.

It would seem like there are countless applications for 100:1 video compression. Defense, security; manufacturing, just to name a few.

I wonder what the data quality difference between our current P-3C "Huricane Hunters" vs. the drone is.  Mission time is much less than the drone; just thinking about data quality.
