In Hungary a young research group (Interspect) presented a high resolution aerial remote sensing technology and the World's highest spatial resolution ortho image mosaic. It's available at www.aerialrecord.com
They made it by a Piper aeroplane (!) at 0.5 mm spatial resolution.
I've been thinking. We can do it with slow flying drones, but how can it work from an aeroplane. I heard an interview. 83 m/s ground speed requires a very fast shutter.

1 mm has already been done with one of our UAV helicopters with a big lens at low altitude. Just not published.
It was my fault. They wrote 0.5 cm (5 mm). Sorry... :)
it is 5 mm indeed: "A pixel is suitable for displaying units of half a centimeter width". 5mm is still very good resolution.
Assuming shutter speed is probably 1/10000 s at best, they must have used some kind of optical stabilization to compensate for motion blur.
Great image but how comes that I get the feeling that it is nowhere near 0.5mm resolution but more like 5mm? I can't read the time on the clock of that guy. That should be possible with 0.5mm resolution since the cursors are at least 1mm thick.
Whoa looks great! Must have been low and zooming in an awful lot!
