Hi Dan,
I’m trying to install the spdviewer in Mac and experiencing the following
errors.
My commands are in red, Am I executing the code correctly?
Please help me to get it installed properly.

Hi Narsimha,
The simplest solution is to install to a separate conda environment and switch
between them use something like:
conda create -n spdlib_v3_2 -c osgeo spd3dpointsviewer
This should work under Linux or Mac. The conda documentation has more info on
using environments.
In future can you make sure you reply to all so the list is also involved in
discussions.
Thanks,
Dan

Hello Dan,
Is there any standalone version available just to view the points ? Either in
UNIX or Mac versions?
I'm very poor in programming and to be honest just building my skills with the
spdlib user guide.
I would like to view the Spd files and start further processing.
Sorry for asking many favours and thanks for understanding the panicky student
tales 😀
Please let me know the simplest solution for now.
Regards,
N

Hi Narsimha,
I haven’t rebuilt the points viewer for conda yet - the recipe is available
from:
https://bitbucket.org/danclewley/conda-recipes/src/bfc2905875b05f5aa7757b311c4241c207973d90/?at=conda-forge
if you want to try modifying this and building yourself. I was having some
problems with Qt, I’ll probably have another look at next weekend. Another
option is to install the old version in a different conda environment and
switch to this for viewing data.
SPD files are compressed but contain a lot more information than LAS files. If
the HDF5 compression is working correctly I don’t think there is an easy way to
make them smaller.
For the bin size I would normally choose based on the point density.
Thanks,
Dan

Hi Dan,
I was trying to install the spd3dpoints viewer in HPC environment and below are
the errors.
It is observed that it’s downgrading the whole spdlib latest version??
I would like to view my test data in the viewer, any advice on this please?
For my sample conversion I was trying to explore the file sizes by defining
different bin parameters.
Do you think that the final output sizes are reasonable? Is there any way to
further compress the file sizes? What would be the ideal bin size could be?
For binsize 10:
LAS file size:391.1MB
SPD file size:380.2MB
For binsize1:
LAS file size:443.2MB
SPD file size:386.2MB
Thanks,
Narsimha

Hi Narsimha,
There will be a WKT (Well Known Text) string embedded in the LAS file, so you
can just view using lasinfo then copy and paste into a text file. The format
will be similar to this: http://spatialreference.org/ref/epsg/28355/ogcwkt/
(you could also just use this file).
This is just a workaround for a bug, I had only tested with LAS 1.3 files so
hadn’t tried with LAS files containing WKT strings. I’ll try and fix at some
point so it will read the WKT string from the LAS file.
Thanks,
Dan

Hi Dan,
I have downloaded latest Miniconda and Python 3.5, it's in HPC environment.
I'm not really sure about .WKT file is?
My data is in GDA94 MGA Zone 55 .
Data provider didn't provide any seperate . WKT file.
Is there anyway that I can develop this?
Cheers,
Narsimha

Hi Narsimha,
This isn’t the latest version, the latest version is 3.3. Are you using Python
3.5?
Try creating a new environment and forcing the version using:
conda create -n spdlib_v3_3 -c osgeo -c rios -c conda-forge spdlib=3.3.0
You will also need to pass in the projection as a WKT file using --input_proj
as it is currently segfaulting when trying to read the projection from a LAS
1.4 file.
As I said earlier this has only recently been added and not widely tested so
expect a couple of problems.
Thanks,
Dan
