Joseph, These Oxford Archaeology guides provide some excellent material for an Open Source Surveyors presentation. Thanks for the link.

Re: [OSGeo-Discuss] What GeoSpatial Open Source Software do Surveyors use?
Maria, Under what circumstances should we recommend people use GRASS over Terrasolid Terrascan, and under what circumstances should they stick with Terrasolid Terrascan? I can see that GRASS is better if you plan to write your own algorithm, because you have access to the source code. I'm hoping that we can recommend GRASS for more than that?

Re: [OSGeo-Discuss] What GeoSpatial Open Source Software do Surveyors use?
Hi Cameron, You might find these Oxford Archaeology produced guides interesting: http://openarchaeology.net/project/survey-and-gis-manual There's also the MapAction Field Guide to Humanitarian Mapping: http://www.mapaction.org/content/view/183/59/ If you're looking for a couple of real feel good use cases (although I can imagine it may not be 100% applicable to what you're doing), there's the amazing work conducted by various people (Mikel Maron and Robert Soden spring immediately to mind, although there are many more) mapping Haiti and Kibera, Kenya into OpenStreetMap.

I'm wanting to convince Open Source skeptics that there is robust Open Source Software available for surveyors which they can use right now. Eg, here is a list of tasks that surveyors regularly perform: Task 1: * XXX organisation (ideally big name organisation), uses YYY OS software to achieve task. Task 2: ...

And for building survey? Well, we're doing some work with various open source tools to generate dense point clouds from photos; we think the resulting output could reach millimetre accuracy using known cameras/lenses and with many shots. Photograph, process, measure at your leisure... And a lovely 3D photo-realistic model for client as an output too! Does that count?
