I want to measure tree heights in the forest using drone photogrammetry. So far it's easy to measure single trees height using fugroviewer in the pointcloud, but I would really like to measure whole groups of trees.

This picture below represents the tops. Is there a way to spot them out into the attribute table?

The tops of the trees

This is another image from before the treetops has been isolated. enter image description here

I'm not a big GIS expert, so please be really specific in your explanation, if you have an idea.

    The title of your question is about COUNTING tree tops then your question is about MEASURING height, edit your title/question to make it clear what you are asking.

  • have you ever tried fusion (forsys.cfr.washington.edu/fusion/fusionlatest.html) it can calculate tree heights and bare earth dem. It then uses those to create points and polygon representing individual trees with heights.
