compare distance of trees to pwerlines

Post by cwat »

Hello! Very, very new to using lidar data and CC so hopefully what im looking for is actually possible?

I have a LAS file that I have classified into powerlines and trees that I have split into 2 files using Edit>Scalar Filter then split based on the point values.

What I am trying to do is identify all the trees within x metres of a powerline and have them symbolised from red to green based on their proximity to the wires. Something along the lines of this

Would the distance computation be the best way to achieve this?

If you keep the power line as a cloud, then you can use the C2C distances indeed (Tools > Distances > Cloud/Cloud dist.). Make sure to set the power line cloud as the 'reference'. And you'll probably want to set a 'max distance' value to avoid too long computations.

Another option is to trace a polyline over the power line (with the 'Trace polyline' tool). You'll then be able to compute 'Cloud/Primitive' distances. It will be more accurate as the polyline doesn't have holes.
