I assume this is for an SPD Version 3 file? SPD version 4 is not supported
by SPDlib.
The quickest option is probably to write a converter using the SPDLib
python bindings (spdpy). Read the LVIS data using h5py and then write to
SPDV3 using the bindings.
You can see an example of writing to SPDV3 using the python bindings here:
https://bitbucket.org/petebunting/spdlib/src/4f115f4af113133de289970186f3022ddd924ab7/python/importers/geolasgcw2spd.py?at=default&fileviewer=file-view-default
Incidentally, I got a similar query from the LVIS team a couple of days
ago... let me know if you get stuck. We're planning a Pylidar LVIS driver
to handle these Gabon data but won't get onto it until February sometime.
John.
