Re: [OSGeo-Discuss] Tools and approaches for the cartography of archaeological excavation sites
You might be better on the Open Source Archaeology list :) http://list.iosa.it/ Speaking as a non-archaeologist working in archaeology, precision of millimetre is nonsense, achieved or not, as (a) the things they are recording were not built to that precision, nor in many built-structure cases even designed and (b) stuff in the ground for that long has moved... CAD doesn't make sense, even though commonly used, as CAD (as any engineer will tell you) is a design tool, not a recording tool. GIS makes much more sense for the majority of recording as the data will require much analysis to be really useful, and a map can be later produced via Inkscape. We have a member of staff who's developed a nice survey workflow using QGIS and Inkscape.

I pretty much see which sensors and software to use for the small scale part, where standard GPS precision is enough. But the most important part is a large scale work, where they need a much higher precision in order to position their findings and draw very precise maps of the excavation sites.

Hi Mathieu, Expanding on Chris' point, you might want to check out the manuals we have here: http://www.openarchaeology.net/project/survey-and-gis-manual Cameron Shorter mentioned them in a presentation he did - I seem to have lost all original links, but here's an embedded video: http://blogs.thehumanjourney.net/finds/entry/geospatial_open_source_for_surveyors And we have our own gvSIG release too: http://oadigital.net/software/gvsigoade Cheers, Joseph On 5 November 2010 10:21, Chris Puttick chris.putt...@thehumanjourney.net wrote: You might be better on the Open Source Archaeology list :) http://list.iosa.it/ Speaking as a non-archaeologist working in archaeology, precision of millimetre is nonsense, achieved or not, as (a) the things they are recording were not built to that precision, nor in many built-structure cases even designed and (b) stuff in the ground for that long has moved...

I've seen some pretty technical discussion of high precision open source hardware on the foss-gps list.
