[Liblas-devel] Re: pondering about LAS 2.0 (was LAS Schema)

[David C. Finnegan]

I think the problem with 1.3 is that everyone is super excited about full
waveform LiDAR data and is really looking to get their hands on it. That
said, if there was a LAS spec that supported true full waveform data most
people and software platforms would not understand how to view or process a
waveform. The vendors who create full waveform sensors such as Riegl, Leica
and Optech are really the only ones that will have software to view and
process the data in the near future. Really, the end user just wants points
that were derived from full waveform sensors. 7 returns is not considered
full waveform...Sorry 1.3...

Ideally, like Martin implied. Waveforms should probably be separated from
the point data so that it¹s an option. Or a compressed version of the
waveform in the file somewhere might help:-)
