Hi Narsimha,
Both the commands you wrote will convert all the returns in a LAS file
to an SPD file. The -x option specifies the type of return to index by.
That is, the pulses are placed into spatial bins according to the
location of their FIRST_RETURN or LAST_RETURN, whatever you specify.

Hi,
I would like to convert .las files to _spd_ format. (Discrete > SPD)
I have seen two different examples regarding the conversion of LAS to
SPD formats. ( one is with first return and other with last return)
Can you please let me know which one is the correct one that suits my
needs? Can I choose ALL returns?
spdtranslate --if LAS --of SPD -b 1 -x FIRST_RETURN
spdtranslate --if LAS --of SPD -b 1 -x LAST_RETURN
Appreciate your feedback.
Regards,
