This is a compressed orthomosaic of a 1-ha plot of mallee bushland near the OzFlux tower at the Calperum station located within the Riverland Biosphere Reserve in South Australia. Environment Institute researchers, Lian Pin Koh and Wayne Meyer, spent a day in the bushland mapping this area.
The images were captured using a 3DR Y6 multirotor flying at 40m above ground level carrying a Canon Powershot SX230 running a 1-second intervalometer script (CHDK-hacked firmware). Photos were geotagged using the mission log from the drone.
It was late in the winter afternoon when this particular flight was done. So the light condition was less than ideal. But the images were still reasonably good. The ground resolution of the images was 1.21 cm per pixel.

cool, thanks Scott
@Craig here is my mount - SUPER simple. I use the hand strap tied to the frame in case it comes loose.
Craig, that's an impressive result. (For others who want to dabble in stitching photos together as a 3D surface using a free tool, check out http://www.123dapp.com/catch.)
@Scott, would be interested in seeing a picture of your mount on your X8, trying to figure one out for mine
@Lars, thank you very much for the link from your blog on the Autodesk123D program, just started playing with it, but is is working quite nice, will continue to follow your progress, thanks again
Really beautiful, did you made any image processing or those are the rough images.
Wow, down to the small branches on bushes, even in lower light levels. A link to this blog post has been added on the 'Aerial mapping' page to enable faster, easier discovery by those who aren't always online watching the DIYD blog posts. Related information can be found on the 'UAV payload item' page and sub-term pages. More on other 'UAS topics' pages.
That's a beautiful resulting mosaic and an astonishing final resolution. I tried something very similar recently, aiming for a 3D mosaic. I also made use of a CHDK intervalometer. I have described the steps in detail on my blog. Which software did you use to stitch the images together?
One more question. How are you mounting your camera? I have tried a solid mount with aluminium near the rear (simple right angle, very light and simple) but worried about the vibration.
Thanks @lianpinkoh - will try out a few here and see how it goes :-) I am inspired.
