Dear Cameron
if you are interested also in LiDAR data filtering (to obtain from the
LiDAR point cloud the digital terrain model), we developed commands
into GRASS. They have to be used in sequence.

A detailed description is available here:

a more recent and summarised version can be found here:
http://geomatica.como.polimi.it/corsi/remote_sensing/LiDAR_filtering_with_GRASS-lab4.pdf
We worked also on calibration of the filtering parameters (around 20
parameters) by integrating the USGS UCODE and GRASS. Details are
available here:

I hope it helps.
Cheers.

I'm giving a presentation on GeoSpatial Open Source at the

Surveyors conference here in Sydney.

I'd like advice on what use cases and Open Source packages I should
focus on during the presentation.
Feedback from Surveyors welcomed.
