GSoC Buffer Implementation

This page will show my progress on my GSoC project (Abstract)

Bugs in current implementation

• v.parallel, v.segment
  • See Ticket #90. Try the following to recreate the bug:

v.parallel dist=500 input=railroads output=rail_par500
g.region n=4928200 s=4921100 w=605600 e=613200

• v.buffer
  • A bug from old RT tracker. Both of the output maps are bad. See pictures on the first row here
