I would like to know what you guys think about the possibility to have multiple returns (let's say ... 3 or 4) in your current systems?
If you think it could be helpful, how would you expect to use that information?
I have a good use for it, like for example, surveying in terrains surface (for DTM purposes) when a sparse bush is present. I could use the very last return, expecting to get the real (or as close as possible) ground.
In my opinion it would be great. And you guys?
