[OSGeo-Discuss] What GeoSpatial Open Source Software do Surveyors use?

[Cameron Shorter]

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?
