Reducing low vegetation in Dense Cloud + "Editing Report"
« on: February 15, 2021, 04:28:10 PM »
Hi all!

I´m trying to determine the difference in volume of various mounds of earth inbetween two drone flights. The problem is, that in the first flight there was vegetation all over the place, so the volume I am measuring is somehow vague as the altitude on top does not represent the top of the material. In some areas it is hard to identify the top of the material (see attached). Is there a way to filter/edit/... the Dense Cloud to reduce the undergrowth and work with the surface of the material?

I tried:

-  Classify Points + filter by class
-  Filter by Confidence
-  Filter by Color
-  manually selecting obvious areas

It is getting better, but it´s still not good.

My second question is whether there´s a way to generate some kind of "editing report" which would document filters I used and generally show how I edited the Dense Cloud (and what kind of inaccurracy I created by doing so)?

I am new to this forum, so I hope I didn´t overlook an already existing answer :o
Cheers and thanks for any kind of help-
