 Metodo Aramus
In 2006 we joined the Aramus Excavations and Field Scholl. That one was our first year in the project as a society. Our primary goal was to help in software migration from closed source softwares to FLOSS. The migration ended without problems, thanks to ArcheOS, but it caused some minor changes in the archaeological workflow. One of most important was the new methodology we had to develop in order to performe a fast photomapping technique of the excavation (at least as fast as the system they used before). We called this new methodology "metodo Aramus" and, untill now, we are still using it. The main reason is the quality we reached with the georeferenced photomosaics: compared with other traditional techniques, every single photo in the final image is equlized in brighteness and contrast. The result is a composite picture in which is more or less impossible to recognize the borders between the single photos.  

Archaeological drawing from photomapping

IMHO one of the main benefits of photomapping is the fact that everybody is able to do good archaeological drawing. In this way it is not necessary to divide archaeologists between "diggers" (who simply excavate layer by layer)  and "drawers" (who just document). In our (Arc-Team) experience it is never a good solution when someone has to document a situation he does not know (because was exposed by someone else).
In other words, photomapping techniques and GIS allow also normal archaeologists to reach the same quality level of professionals in drawing layers or finds. As an example, the picture below shows the skeleton of a young goat found in Aramus (AM): the georeferenced photomosaic is done with photomapping techniques ("metodo Aramus") and the drawing is done by me (i am not a professional in drawing) using the GISOpenJUMP (inside ArcheOS).

Good news from PMVS2

According to Pierre Moulon's Blog a new implementation (from Nghia Ho) has been integrated in CMVS-PMVS. The result should be a faster (up to 30%) data elaboration. We will start with the test as soon as possible and, in case, a new ArcheOS package forPPT (Python Photogrammetry Toolbox) and PPT-GUI will be released. For who wants to collaborate in PPT-GUI development, here is the link on GitHub.
In the video below are some archaeological examples done with this software.
