[pdal] Invalid dimension name 'Pulse width'?

[Andrew Bell]

Hi Riivo,

There's nothing wrong with the name. PDAL doesn't support spaces in
dimension names, so it fails. We've seen spaces in dimension names in other
formats (BPF and text, for instance), but this is the first I can recall in
a LAS file. I'll open a ticket to add an option to allow PDAL to accept
this by replacing PDAL-invalid characters with a '_'.

You should be able to get PDAL to read the file for now by modifying it
with something like sed:

$ sed s/Pulse width/PulseWidth\000/ < infile.laz > outfile.laz

Hope that helps,
