supersquint,
With all this posting about image capabilities, it got me thinking that I had heard or read about stereoscopic imagery being used in the 1940's WWII. Looks like they do a similar kind of thing today in the non-visible spectrum (i.e. microwave phase compared blah blah etc,) but I was wondering if stereo visual spectrum images were in use. Is this kind of thing still in use?
(The thought got me so intrigued, I pulled out some old family stereoscopic slides from the 1950's. Really Cool!)
The big thing in aerial imaging now is spectral imaging and hyper-spectral imaging. And now they're even going further by coupling hyper-spectral imaging with some really cool laser optical and laser radar sensing stuff. It would be a cool time to be starting out as a young undergraduate as a science major in this area. Except like the guy up above here said, the security and other job related risks are a consideration right now.

How about this new toy? http://www.click2houston.com/investigates/14659066/detail.html
If that'll work as they pretend and if CAP and other rescue teams will have access to those too, then we here can stop worrying about Internet SAR and GE imagery and image quality and image analyzing IMO.
The article mentions that the craft was being operated by staff from a private firm called Insitu, Inc..[ http://www.insitu.com ] The device in the video looks like the firm's ScanEagle [ http://www.insitu.com/scaneagle ]

When I was an Urban Planning student, someone was saying(I don't remember who)that the gov had satellites that could "IMAGE" a toothpick IN REAL TIME on the street.
( Is this comparable to the?.......Detect Individual Spikes In Railroad Ties... in the Visible Column of the NIIRS 9 (less than 0.10 m GRD)
http://www.fas.org/irp/imint/niirs.htm
that Blu Penguin just posted...
or a MILLION x's better than what THEY WOULD LIKE YOU TO THINK!)
That was before they did away with the whole UNDERGRADUATE PROGRAM, and it was probably before they even paid for the new building, it seems. The Undergrad Curriculum, which included this Remote Sensing coursework was only one of 4 IN THE NATION before they canceled it. Just recently, the department's secretary was killed by her boyfriend. Even more recently, a student from the same University is being held in an Italian prison for the murder of her roomate overseas. These are bizarre events, so bizarre, I gave up education AND employment in this Boeing, i.e. govt. contracted, area. They are like the Catholic church in South America. If you LIKE BLACK TARPS WITH UGLY HAIRY FEMALE LEGS under them, you are doing great!
At this same University, you can't major in Photography and Nursing, someone told me....it just goes on and on and on and on....
Your perspective is different than most. Usually I can look at the picture you are describing by connecting the points in your post, but sometimes you lose me.
Not all habits are black, some are brown, and some are even blue. And as for tarps, although they are almost always used to cover up something, that something is most often an inocuous something, like camping supplies or donkeys being shielded from the rain.
Looking at the various satellite and aerial images, I've learned it is important not to infer or speculate beyond the limits of the resolution or I may begin to see things that aren't there, .....like broccoli. Generally I've found this to be a good and useful policy for me, but then, some peeps have better vision than me.

The way I see it, small drones like this can "inexpensively" capture the aerial imagery needed at high enough of a quality for easy IA and with the proper tools in place volunteers can be quickly mobilized to analyze said imagery for a lot less money that a room full of high priced computers running even more expensive software. My idea is that aerial imagery analysis can be inexpensive enough and cost effective enough that it can be utilized for "routine" SAR missions of the average Joe/Jane pilot, not just the rich and famous.

The code named Kennan "Keyhole-class" (KH) reconnaissance satellites have been orbiting the Earth for more than 30 years. They are typically used to take overhead photos for military missions. KH is a satellite that resembles the Hubble Space Telescope, except it is looking at our planet.
The satellites are often placed into various secret orbits by NASA space shuttles or Titan 4 rockets and managed by the National Reconnaissance Office (NRO), headquartered in Chantilly, Va. Digital images from the satellites are analyzed, manipulated and combined by powerful computers at the National Geospatial-Intelligence Agency (NGA).
Almost everything about these satellites is classified. Nevertheless... This is the NASA which launch your satellites...
USA-53/AFP-731 "Misty-1" was launched by the Shuttle STS-36 on 28 February 1990.
USA-144 (1999-028A) Idenfitied as KH12-4 in NASA's database, "Misty-2" was launched on 22 May 1999 by a Titan-IVB (with no upper stage) from Vandenberg AFB.
"Misty 2" is a stealth satellite in a 700-800 km orbit. The shorter off set telescope is a Lockheed, Perkin-Elmer Corporation design verses the suggest imagery telescope optics designer used on the KH-11 KENNON, and Hubble telescope design heritage. Misty shorter telescope uses a large front flat black colored photo shutter window that allows for a wider field of view.
USA-161 (2001-044A) was launched by a Titan 4B rocket from Vandenberg AFB at 21:21 UT on 5 October 2001.
USA-186 was launched on 19 October 2005 by a Titan-IV from Vandenberg AFB.
The KH-11/12/13 series are planned to be replaced by the planned Future Imagery Architecture digital imaging spacecraft. The contract for these planned spacecraft was initially awarded to Boeing in 1999, but in September 2005 the contract was shifted to Lockheed after cost overruns and delays of the delivery date. Each costs in excess of US$1 billion with a further US$400 million spent on launch costs.
Image quality:
KH-13 satellite: The theoretical ground resolution with no atmospheric degradation and 50% MTF would be roughly 0.15 meter (6 inches). NIIRS Level ?
Quickbird satellite: 2’ (60 cm) NIIRS Level 5
"Typical" U-2: NIIRS 7
RQ-4 "Global Hawk": Electro-Optical: NIIRS 6.0/6.5, Infrared: NIIRS 5.0/5.5
http://www.ae.utexas.edu/ASE261KChaput/referencematl/GH_System_Desc.pdf
MQ-1 "Predator": NIIRS 7, Infrared NIIRS 5. These high NIIRS levels can be achieved only in some circumstances on UAVs flying low-altitude missions. Medium-altitude missions are flown in the altitude range of 2000 to 25,000 ft. These missions use systems with focal lengths from 180 mm up to18 in. to image an area up to 10 miles wide. Predator has an NIIRS of 6 for this typical mission, which corresponds to distinguishing objects of less than 1 m in size.
I believe that only aerial Photo may be equivalent to NIIRS 9. But there is very good reasons for letting the "enemy" believe that you can take this type of photos by satellite, I mean without sending a plane, a crew, and a very sensitive equipment right over his head in his civilian aerial space...

From the article:
"Operators from a private firm called Insitu, Inc. manned remote controls from inside the fleet of black trucks as the guests watched a live feed from the high-powered camera aboard the 40-pound aircraft."
Did you check http://www.insitu.com/scaneagle ?
Seems as if all this can be done in real time while the drone is in the air, according to that site.
And also this: "It can resolve objects such as small vehicles from at least 5 miles away. The operator can command the camera to pan back-and-forth for wide-area search, or to remain locked onto an object while the aircraft maneuvers."
I highly doubt they'll need us armchair dwellers for SAR with that baby.

Kinda ticks ya off-don't it? Here we are trying to figure out how to develop a small but highly effective SAR system to try to help save some lives. Do it for under $10,000. And here comes Boeing and Home Land Security with all the Government cash in the world and they want to use it to hand out traffic tickets. Why didn't they get the damned thing up to NV or up to BC and look for Steve and Ron Boychuk?
Really burns me up.

Some of you guys should do a little Google search on kite aerial photography systems.
These amature photo bugs are doing some really impressive things with on-board digital cameras, 2.4 Ghz microwave transimtters, ground based video recorders, and monitors. All done from a kite or balloon. And most of the time they've spent less than $2,000.
Now don't get me wrong, this is NOT what I'm suggesting for a decient SAR system, just that one could learn a lot from reading about how these guys are doing things for a hell of a lot less than Boeing and HLS is spending for an automated traffic ticket pusher.
