[pdal] Setting all points to a single class?

[Jonathan Greenberg]

That was the trick!  Thanks!  Solution:

"pipeline":[
  "P001_E1_clip.las",
  {
      "type":"filters.assign",
      "assignment" : "Classification[:]=101"
  },
  {
  "filename":"P001_E1_clip_tclass.las"
  }
]
}

pdal pipeline reclasspipe.json
