[pdal] Empty GeoDoubleParamsTag

[Farwell, Michael]

Hey All,

Using PDAL 1.5, I'm trying to decompress a LAZ file and then re-project it into UTM using the following pipeline:

{
  "pipeline":[
    {
      "type":"readers.las",
      "compression":"laszip",
      "filename": "/tmp/in.laz"
    },
    {
      "type":"filters.reprojection",
      "out_srs":"EPSG:32619"
    },
    {
      "type":"writers.las",
      "filename": "/tmp/out.las",
     "minor_version": 2
    }
  ]
}

Since the minor_version is "2", PDAL is using the GeoKeyDirectoryTag  to store the georeferencing information.  Unfortunately, PDAL is writing out an empty GeoDoubleParamsTag.

"vlr_1": "",
    "vlr_1":     {
      "description": "GeoTiff GeoDoubleParamsTag",
      "record_id": 34736,
      "user_id": "LASF_Projection"
}

Is there any way to prevent PDAL from writing out this VLR if it's empty?  Or is there a way to remove it with another pipeline?

Thanks,

Mike
