Tools for Point Clouds?
Can I use my Point Cloud (derived from UAV) in eCognition to generate a DTM or DSM? Or do I Need to create These layers outside of eCognition!?

Hi Ace,
Yes you can! You can import any point cloud into eCognition as long as it is in one of the supported formats (.las or .laz). Within eCognition you can view this point cloud in 3D, derive raster files (such as DSM & DTM), actually based on any information stored in the point cloud. You also can classify the point cloud, create point clouds, remove points from point clouds, classify point clouds, etc..
There is a fairly nice video available on the algorithm "rasterize point cloud":

I also found these two webinars here:

And a very nice example by Christian where he uses a point cloud to extract single trees!:

There is actually more, but this should give a nice oveview.
Cheers
Thank you for your answer and the links! Very helpful Information!
