[Liblas-devel] Drivers

[Finnegan, David ERDC-CRREL-NH]

Mike,

Have you considered how encoding full-waveform data other than Leica will
have to be done in version 1.3. The 1.3 definition is basically written for
Leica data and really doesn't support easily writing other vendors formats
like Riegl. I've heard of a few people doing their own work arounds but it
often means tossing out any relevant calibration information for future use.

This sounds like a nice improvement, especially allowing one to read a wider
range of formats.  We've been working on a few tools for internal (and
hopefully external) use, including a viewer, that use liblas for data reading
so it'd be very useful to us.

We're particularly interested in LAS 1.3 support (and were planning to offer
sample data and coding time implementing if needed) as we've recently
acquired a full waveform digitizer for our Leica LIDAR*.

If you're working on a refactoring, it'd be worth bearing in mind the
integration of full waveform data.  Any thoughts on how this might be best
implemented?

Cheers,

Mike.
