I have a lot of LAZ files and generate a couple of polylines in ArcGIS. for these polylines I need to extract the points classified as 'ground' from the LAZ files.

What transformer allows me to do that, and how to deal with polylines intersecting with several LAZ files?

Thanks Tom,

 

your suggestion works fine!

I ended up using the SurfaceDraper in connection with a VertexExtractor.
