> I'm trying to simplify a contour map I've done with r.contour. I want to remove small area but when I use the command v.edit map=<map> tool=delete thresh=1000 query=length, only "non-closed map" are considered and the "closed line" (there are really lines, not polygons) remain.
Hello,
did you try to transform your line vector into a polygon vector and use 
after a v.clean command with tool=rmarea ? So only the small area will 
be removed and after you can again transform your polygon vector into a 
lin vector
