Hello to all,
First of all thank you all for the great work you are all collectively
doing, I'm very often impressed by the power of open GIS.
I have been struggling with a problem on Grass 6.4.3RC1 and 6.4.3RC2 with
the v.overlay.and function.
I tried to clip a line network on a single polygon, and the output is
wrong : some lines are missing, some lines are there that should not be.
The problems occur with lines that intersect with the polygon's boundary.
I tried with different sets of data, and with simple features I created
for the test in Grass. Same wrong results.
I tried to use the same data with Grass 6.4.2 on my computer and on other
computers runnig 6.4.2 and it worked on all PCs.
I tried to upgade one PC in 6.4.2 to 6.4.3 and did the same test :
v.overlay.and produced the same erroneous output.
NB : I setup Grass 6.4.3 on my PC through osgeo4w, and 6.4.2 through the
windows standalone installer. I also just tried with the 6.4.3.RC2
standalone installer and the output was also wrong.
If it wasn't for my boss, I would switch from Windosw to the Dark Side of
the Force...
Can someone else test this function in 6.4.3 ?
