[pdal] PDAL pipeline issues with large datasets

[Michael Smith]

Also, the conda version of 2.4.2 should show 

 

pdal --version

------------------------------------------------------------------------------------------------------------------------------------------------------

pdal 2.4.2 (git-version: Release)

 

 

Maybe you need to recreate your conda install or use the conda version of pdal if you are not.

Subject: [pdal] PDAL pipeline issues with large datasets

 

Hi All,

I’m trying to get pdal pipeline working with the latest install of pdal via conda. It works for very small areas but is erroring out on larger selections.

 

The pipeline.json file is

 

{

  "pipeline": [{

    "type": "readers.ept",

    "filename": "https://s3-us-west-2.amazonaws.com/usgs-lidar-public/USGS_LPC_TN_Middle_B2_2018_LAS_2019/ept.json",

    "bounds": "([-9666713.882998705, -9662911.140841518], [4283077.817410117,4287281.853965801])"

  },

  {

    "type":"filters.reprojection",

    "in_srs":"EPSG:3857",

    "out_srs":"EPSG:32616"

  },{

    "type" : "writers.las",

    "filename": "points.laz",

    "a_srs": "EPSG:32616"

  }]}

 

 

The version of pdal (via conda) is

 

pdal --version
-----------------------------------------------------
pdal 2.4.2 (git-version: e4772e)
----------------------------------------------------- 

 

I have tried it on two machines with both Ubuntu 22.04 LTS and Ubuntu 18.04.

It seems to work with PDAL version 2.4.1.

 

I see the following error:

PDAL: readers.las: VLR 1(SF/0) size too large -- flows into point data.



Maybe I’m missing something. Is anyone else having this issue? Can anyone please advice? 

Thank you!

- Vishu
