The animations

were generated from the Lidar pointcloud coloured by the RGB-imagery.

 

All data is from the flight - no ground-based data.

 

Download the data from here (AH) and here (KI).

Watch the videos here or

directly on VIMEO.

There you will find more.

And here are two media items about this project plus a Visual Story and a 3D-Animation

MUST SEE:

There are now also two 3D-interactive views of the Lidar pointcloud - click the image - and make sure you set POTREE to "High Quality".

Zoom in to individual tree size.

To our amazement, we even found two eagles

soaring over the forest. And yes, these are eagles, the lager one has a wingspan of 1.48m.

Check it out yourself in the POTREE animation !

In airborne Lidar data one can remove trees
without bushfires or cutting them.
 
That's a very powerful feature to detect structures
usually hidden by trees or other vegetation.
