Hello Gerardo, After seeing how long it takes to load and view a large file in qgis 1.5.0 I see the advantage of using smaller excel files of one or two degrees lon and lat. Do you know of a quick and easy way to join points with attributes of similar values of a txt file into polygons? Is it easier to do it as a cvs text file in excel or once loaded into qgis. Any suggestions will of course be much appreciated. thanks, J.R.
