<DIV>I'd like to confirm Paolo's statement from my experience teaching qGIS to local staff of the Ministry of Environment in Mozambique</DIV>
<DIV> </DIV>
<DIV><STRONG><EM>Some annoying bugs I came across is </EM></STRONG>(I am not sure to which extend this are known issues - if need be a can give more details)</DIV>
<DIV> </DIV>
<DIV>* with the <STRONG>geoprocessing tool (0.41) </STRONG>doing a clip operation, clipping points with a polygon - worked fine when it concerned a single polygon (boundaries of a province), but when it was a complex polygon - a province defined by several district boundaries - some of the points got lost !!! It worked well doing it in GRASS though, (but for beginners it is confussing mixing GRASS with qGIS); in the geoprocessing tool it's actually called <STRONG><EM>intersection </EM></STRONG>- would be more appropriate if it were called <STRONG>clip</STRONG></DIV>
<DIV> </DIV>
<DIV>* I also had trouble joining polylines (roads), the geoprocessing tools 0.41 - seems not to work with line type (really only with polygons ?) and the plugin "spatial operation" (version 0.2) seems to allow it, at first - but refussed alleging that the layers are in different projection systems (while they are not).</DIV>
<DIV> </DIV>
<DIV>Interesting doing the clip operation (as explained above) with this tool (cutting out points with "district polygons") also lost some points on the way (though less) and shifted the points a little bit south east wards ...</DIV>
<DIV> </DIV>
<DIV>* and a last point I like to raise - and I know it's I known issue - it is really a pitty that you can't have labels automatically aligned with lines (say name of rivers along rivers or elevation along contour lines - as this is straightforward gvSIG ... For me this should really be something to work out (as a fix may be a tool which adds the local angle of a line segment in attribute table automatically would already be great)</DIV>
<DIV> </DIV>
<DIV>Cheers and many thanks to all those who are developping this great programme</DIV>

Every time QGIS is visibly more<BR>stable and more powerful.<BR>Special highlights:<BR>- the search tab fo GRASS modules: this saved a lot of time, workflow<BR>was much more pleasant and fast - thanks Tim!<BR>- plugin modules: this caused a lot of people lowering their mandibles<BR>for the power they give and for their ease of use; we spotted several<BR>bugs, wrote to Carson, and most are already solved. I strongly suggest<BR>to include them (at least
fTools and Table Manager) in the SVN, and<BR>install them as default: in my opinion we cannot afford missing them.<BR>In the meantime, we found several bugs; I'll fill up the trac soon.<BR>All the best, and lots of thanks to all devs!<BR>pc<BR>-- <BR>Paolo Cavallini, see: * <A href="http://www.faunalia.it/pc" target=_blank>http://www.faunalia.it/pc</A> *<BR>_______________________________________________<BR>Qgis-user mailing list<BR><A href="mailto:Qgis-user@lists.osgeo.org" ymailto="mailto:Qgis-user@lists.osgeo.org">Qgis-user@lists.osgeo.org</A><BR><A href="http://lists.osgeo.org/mailman/listinfo/qgis-user" target=_blank>http://lists.osgeo.org/mailman/listinfo/qgis-user</A><BR></DIV></DIV></div><br>Send instant messages to your online friends http://uk.messenger.yahoo.com </body></html>
