dear users..
I have this problem:
I have a lot of areas in a vector map, each one which have a different
cat value
each area should not be touched by an other one. (they are querries
areas and there are no holes in the single querries)
but when I do v.build I obtain 477 aree and 476 isles...
this mean that there are two area toutching themself
this is an error... I need only shared areas...
so, the question: how can I find the two touching areas automatically???
thanks for your answer...
