Hi all! It's Kiara. I am using a script to overlay two shapefiles, respectively line and polygon type. The overlay operation gets stuck at approximately 74%, and it happens in the script, by command line and also by using the grass toolbox in qgis. maybe the problem is the number of vertices? More info: (ALL_ROUTES_M1SO6 is the line map, prova_conc_grand_grass is a test polygon i'm using)
GRASS 6.4.2 (Europe):~/Desktop/short-term/grass_CODE_NewData > v.overlay ainput=ALL_ROUTES_M1SO6@PERMANENT atype=line alayer=1 binput=prova_conc_grand_grass@PERMANENT btype=area blayer=1 output=routes_overlapped_test2 operator=and Copying vector objects from vector map <ALL_ROUTES_M1SO6@PERMANENT>... 100% Collecting input attributes...

* here I stopped the procedure, and after that I cannot open the map that has been created. My maximum wall time has been 20 minutes...is that normal?
thanks a lot Kiara
