Free GIS and archaeology

In recent years, see CAA 2007, free GIS is becoming more and more popular among archaeologists. Open source and open standards should be the way to go, but the debate about the use of free software is a debate largely postponed in general, but very specially in public Universities and should be confronted without delay. There are very good examples of the use of free GIS, with the same guarantees that commercial systems of extra orbited costs out of the reach of students. In addition to ideological considerations, free gis should be use because it is a better choice. The use of free GIS allows us to benefit from the work of others, at the same time that our contributions benefit others. Without doubt GRASS ( http://grass.itc.it/ ) gvSIG ( http://www.gvsig.gva.es/), (http://www.qgis.org/), uDig (http://udig.refractions.net/), are tools with capabilities similar to commercial software. The idea is to have different examples about how those Geographical Information Systems deal with archaeological problems offering to participants a current update of how much Free Gis have been developed in recent years. The growing availability of web data services through protocols like WMS or WFS are the perfect companion to free gis allowing archaeologist to manage free spatial and accurate data.
