Just to give the solution I found:<br>
I use gdal_retile.py now for preparing tiles from my large GTiff
files. Besides: Using a clean Ubuntu 20 docker and install pdal
works fine. pdal/pdal:2.2 also does, pdal/pdal:latest does not<br>
<br>
Thank you for everybody helping!<br>
<br>
This does however lead to another question:<br>
is there a way to stop the execution of the writer in a pipeline
where the first filtering stage has an empty result - no points?
Or am I missing something. Please bare with me, I'm new to PDAL.<br>
```<br>
{<br>
"pipeline":[<br>
{<br>
"type":"readers.gdal",<br>
"spatialreference":"EPSG:4326"<br>
},<br>
{<br>
"type" : "filters.ferry",<br>
"dimensions": "band-1=Z"<br>
},<br>
{<br>
"type" : "filters.range",<br>
"limits":"Z![-32767:-32767]"<br>
}, <br>
# no result here for all points are empty in a border tile, can I
skip the further stages?<br>
{<br>
"type":"filters.chipper",<br>
"capacity":600<br>
},<br>
{<br>
"type":"writers.pgpointcloud",<br>
"connection":"host='pgpointcloud' dbname='pointclouds'
user='someone' password='something' port='5432'",<br>
"schema":"pointcloud",<br>
"compression":"dimensional",<br>
"srid":"4326"<br>
}<br>
]<br>
}<br>
```<br>

<div dir="ltr">While there might be a way to do this in PDAL, it
looks like your problem is a raster to raster operation. I
suspect you'd want to use the tiling capabilities of GDAL (or
similar) first and then use PDAL once you're doing a point
operation.

Having installed pdal 1.6.0 (git-version: Release) in an
Ubuntu docker environment, I receive the following output
from `pdal --help`:<br>
```<br>
The following commands are available:<br>
- kernels.delta<br>
- kernels.diff<br>
- kernels.ground<br>
- kernels.hausdorff<br>
- <a href="http://kernels.info" target="_blank"

- kernels.pipeline<br>
- kernels.random<br>
- kernels.sort<br>
- kernels.split<br>
- kernels.tindex<br>
- kernels.translate<br>
```<br>
I am intending to use pdal tile to split large raster
files before importing to pgpointcloud but it is not
available. I tried installing pdal-doc, both from bionic
universe. Can you please give me a clue how to get pdal
tile installed? <br>
<br>
Thank you very much for your help.<br>
Best<br>
<br>
