The two concepts are so different that I can hardly think of a common base... giovanni > > Pierre > > _______________________________________________ > Qgis-developer mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/qgis-developer > -- Giovanni Allegri http://about.me/giovanniallegri blog: http://blog.spaziogis.it GEO+ geomatica in Italia http://bit.ly/GEOplus
