Hello,

I have a LIDAR test data set, where I am trying to determine the power lines. These are currently in class 0 (unclassified). My first approach now is to select all points with a certain height above ground (and class 0). If the classification 0 is possible without problems, I unfortunately fail because of the classification of the points with a certain height above ground. For this purpose I have calculated a grid with the points of class Ground and the SurfaceModeller and then I check if the points of class 0 are on the grid height. If this is not the case, I continue to use them - but that is not possible.

Another problem (which I haven't investigated yet) is, how do I convert the selected points into a vector?

Is there another approach to extract (power) cables from lidar data?
