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
