Hello, I have been asked to analyze how FLOSS software could help to support an archaeological program that would take place in remote mountainous corners of Central Asia.
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. When they work in Europe they have sensors and are in a context which give them a precision of the millimeter. For this project they know that they won't have access to the same tooling and they could live with a precision of the centimeter. My questions to the list therefore are: - is it relevant to use "our" usual FOSS4G software (GRASS, QGIS, etc.) for such tasks? or do only CAD tools make sense? - do some of you have experience with sensors/methodologies which would provide centimeter order precision, be transportable and usable in remote areas and not too expensive? - more generally, if somebody has experience with similar problematics, I'd be very interested in pointers to documentation, software, sensors... I hope that I am not (too much) out of topic: I must say that it is not yet completely clear to me at how large a scale do GIS stop... Thanks in advance for your comments, Mathieu _______________________________________________ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
