Description

I am trying to create a network from a polyline map with about 11000 categories and a points map with about 24 categories.

I was using v.net with a threshold of 4500 meters (provided by v.distance) and receive the following error:

Assertion failed:!p->taken[i], file split_q.e, line 69

My code was:

v.net input=network points=cdw1c output=network_v1 operation=connect threshold=4500

Cc: dof1985 added
Platform: UnspecifiedMSWindows 7
Priority: majorcritical
Version: 6.4.26.4.3 RCs

Update:

After a long consulation with a generous user from GRASS community, I still havn't came to a solution. I've tried on two computers with WIN 7 as operation system, the following GRASS versions: 6.4.2 (through QGIS and without the plugin), 6.4.3 RCs, 7.0.0

For the first two I have received the same error, for version 7 I didn't recieve the error but the process have never finished. On the other hand, my helper managed to complete it in seconds using my files.

Can the problem have something to do with windows 7, some background or system process, or so? Should I install any extention or plugin in order to run network analysis programs on win 7?

There are currently problems with the database communication in GRASS 7 on windows. The reported bug does not appear in GRASS 7, but the respective differences (spatial index) can not be backported for compatibility reasons.

Closing the ticket as wontfix for GRASS 6.
