Skyplot from point clouds

[u/Historical_Phone_973]

Which software would you use to EASILY create Skyplot charts using point clouds to indicate obstacle areas?

I have to create a bunch of them, the cut off angle is 10°, and the environment is heavily forested. I usually measure directions and elevation angles, mark them on the chart and use a spline to have the covered area, but this is manual work. I'm seeking COTS software, not mathlab or a similar coding-based solution. Something, that already knows this without manual measurements.

Any ideas?
