#3439 new defect

Unclear behaviour of v.buffer -s flag

Reported by: marisn Owned by: grass-dev@…
Priority: normal Milestone: 7.4.5
Component: Vector Version: svn-trunk
Keywords: v.buffer Cc:
CPU: Unspecified Platform: Unspecified

Description

From the documentation is not clear if "-s" flag affects only corners of line nodes or also corners of vertices. To make matters worse – output varies depending on algorithm in use:

  • with GEOS it affects only corners at nodes (line ends)
  • with native it affects all corners (at nodes + at vertices)

As a minimum, documentation needs to be updated to indicate correct behaviour and then a new bug should be filled to fix one of algo's to match expected output.
