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 <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.
