Highest resolution aerial ortho image of the world

3689497801?profile=original
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!
