/I was trying first v.buffer, then v.db.addtable and finaly v.overaly
intersect with input line for buffer. But then is the output line
again.
/
/
can you reproduce the effect using the demo spearfish dataset, and post
the command line commands?/
Buffer 5 meters for layer of roads from sperfish60 dataset
1. v.buffer input=roads output=roads_5m type=point,line,area layer=1 buffer=2.5
scale=1.0 tolerance=0.01
2. v.db.addtable map=roads_5m layer=1 'columns=cat integer, atribut integer'
3. v.overlay ainput=roads atype=line alayer=1 binput=roads_5m btype=area blayer=1 output=overlay_roads_buffer5m operator=and olayer=1,0,0
Output is always a line, however i need the polygon.
