Sony Developing Gigapixel Satellite Imaging 101
holy_calamity writes "Sony and the University of Alabama are working on a gigapixel resolution camera for improved satellite surveillance. It can see 10-km-square from an altitude of 7.5 kilometres with a resolution better than 50 centimetres per pixel. As well as removing annoying artefacts created by tiling images in Google Earth and similar, it should allow CCTV surveillance of entire cities with one camera. 'The trick is to build an array of light sensitive chips that each record small parts of a larger image and place them at the focal plane of a large multiple-lens system. The camera would have gigapixel resolution, and able to record images at a rate of 4 frames per second. The team suggests that such a camera mounted on an aircraft could provide images of a large city by itself. This would even allow individual vehicles to be monitored without any danger of losing them as they move from one ground level CCTV system to another.'"

True it seems that this, if successful could be used that way and, if it all works as they promise would allow for that kind of monitoring (barring tunnels bridges, garages, etc. What I find interesting is that none of them are asking if the should do this or whether we would be better off if they do. Absent from any sort of new surveillance tech reporting is the question of whether such tech is needed or will help if it is used. You know, the kind of questions that reporters should be asking.
But then again this article reads like a standard press job where a press release is sent by a vendor to the press, they (sometimes) call up the contact name, and then print the release in full with no backgound or other assessment. It is a basic way of filling a publication without ever leaving the office or reporing hard stuff. It is also, all too common these days, especially in the print media.
Oh Upton Sinclair, where have you gone?

You could put one on one of them heliostat things, for example, or a solar blimp cruising around at 7.5 km. I for one, blah blah, bug eyed overlords, etc, in their solar powered blimps, et. al.
