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?

  • Read all LAS
  • Filter ground-points (@Component(classification)==2) (PointCloudFilter)
  • Read all polylines
  • Buffer the polylines
  • merge all buffer-area (dissolver)
  • clip the pointclouds (clipper)

Thanks Tom,

 

your suggestion works fine!

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