The first question is which conda channel are you using? The correct channel is "conda-forge" and this channel definitely has 2.3.0 as the latest version for Windows 10 - see
https://anaconda.org/conda-forge/pdal
If you are not sure or are using another channel - remove pdal from your conda environment and re-install with `conda -c conda-forge install pdal`.
If the channel is correct - then most likely you have something installed in your environment that requires a version of one of the dependencies at a lower version than is supported by version 2.3. The PDAL version 2.3 dependencies are :
curl >=7.77.0,<8.0a0, draco, geos >=3.9.1,<3.9.2.0a0, geotiff >=1.6.0,<1.6.1.0a0, hdf5 >=1.10.6,<1.10.7.0a0, jsoncpp >=1.9.4,<1.9.5.0a0, laszip, laz-perf, libgdal >=3.3.0,<3.4.0a0, libkml >=1.3.0,<1.4.0a0, libpq >=13.3,<14.0a0, libxml2 >=2.9.12,<2.10.0a0, nitro, numpy, pkgconfig, postgresql, sqlite >=3.35.5,<4.0a0, tiledb >=2.3.0,<2.4.0a0, vc >=14.1,<15.0a0, vs2015_runtime >=14.16.27012, zlib >=1.2.11,<1.3.0a0, zstd >=1.5.0,<1.6.0a0
the easiest way to check might be to create a new, clean environment, add PDAL (you should get version 2.3) and then incrementally add the packages you need until you get a version clash reported (or something forces a downgrade of PDAL - you should see this in the messages from `conda install`).

Hi Andrew,
May I know how to update/upgrade PDAL 2.3 or latest in Windows 10.
I had tried to update/upgrade PDAL using:
conda update pdal
conda upgrade pdal
But it still gives me the same version 2.1.0 (git-version: Release) in Windows 10.
Please advise.
Thank you.

Hi Andrew,
May I know from which version can PDAl do math in an assignment.
I had tried to update/upgrade PDAL using:
conda update pdal
conda upgrade pdal
But it still gives me the same version.
Please advise.
Thank you.

Your version is too old. You can't do math in an assignment filter in version 2.1. Sorry.

Hi Andrew,
I’ve tried what you have suggested:
[
{
"type":"readers.las",
"filename":"input.las"
},
{
"type":"filters.assign",
"value":"IntnstySqRt = Intensity / 256"
},
...
But it gives this error:
PDAL: filters.assign: Unexpected argument 'value'.
I’m using PDAL 2.1.0 (git-version: Release) in Windows 10.
Pls. advise.
Thank you.

Sorry, I had a typo. It should have been "value" instead of "assignment":
[
{
"type":"readers.las",
"filename":"input.las"
},
{
"type":"filters.assign",
"value":"IntnstySqRt = Intensity / 256"
},
...

But is giving same error:

Please advise.

You're mixing syntax for the older "assignment" option with that of the newer "value" option.
Try this:
[
{
"type":"readers.las",
"filename":"input.las"
},
{
"type":"filters.assign",
"assignment":"IntnstySqRt = Intensity / 256"
},
...

Hi,
I’m trying to generate a GeoTiff image from a LAS file using the sq. root of Intensity dimension and the pipeline as follows:
[
{
"type":"readers.las",
"filename":"input.las"
},
{
"type": "filters.ferry",
"dimensions":"Intensity=>IntnstySqRt"
},
{
"type":"filters.assign",
"assignment":"IntnstySqRt[:] = IntnstySqRt / 256"
},
{
"type":"writers.gdal",
"resolution": 0.05,
"data_type":"uint8",
"output_type":"mean",
"dimension":"IntnstySqRt",
"gdalopts":"COMPRESS=JPEG,PHOTOMETRIC=YCBCR,BLOCKXSIZE=4096,BLOCKYSIZE=4096,GDAL_CACHEMAX=8000,NUM_THREADS=ALL_CPUS,TILED=YES",
"bounds":"([19370,20527],[39571,40865])",
"filename":"output.tif"
}
]
However, error occurred:
PDAL: filters.assign: Invalid value for argument 'assignment'.
Is it the correct use of filters.ferry and filters. assign…
Please advise.
Thank you.
