[pdal] Classify Buildings and Vegetation in PDAL?

[Piero Toffanin]

Hello!

I was wondering if somebody could point me in the right direction; I'm 
trying to classify (roughly) a set of non-ground points into buildings 
and vegetation for the purpose of filtering out vegetation and retaining 
only the buildings. I was thinking of using an approach similar to 
lasclassify (check for planarity or roughness) 
https://rapidlasso.com/lastools/lasclassify/, but I'm not sure which 
would be the best way to approach this.

Suggestions?

Thank you!
