This page will show my progress on my GSoC project (Abstract)
Bugs in current implementation
- v.parallel
- This generates copy of railroads (at least it looks like one). When I try dist=501, things seem alright. See Ticket #90
v.parallel dist=500 input=railroads output=rail_par500
- v.buffer
- A bug from old RT tracker. Both of the output maps are bad.
