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
