Thank you Marina,
That is a good example.
To be complete, could you also answer:
* What would be the proprietary equivalent software you would use?
* Why did you decide to use GRASS instead of proprietary software?
(Hopefully more than "it was cheaper")
* It seems you are officiated with a University? Industry is more
convinced by case studies that come out of industry, as universities are
often associated with "smart geeks, who have a high tollerance to things
going wrong because they can fix it themselves". Is there a
non-education affilition you can draw upon? Did you do this work for a
governement department or similar?

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
international
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.
