I'm trying to connect my network to a points layer with a threshold of 4500 meters. I have about 11000 or so entries in my polyline and about 24 in my points layer.
I have alreday used v.distance, hence the threshold. However I recieve an error (image attached) any time I try the following:
v.net input=network points=cdw1c output=network_v1 operation=connect threshold=4500
Here is the error:
Error content is:
Assertion failed: !p->taken[i], file split_q.e, line 69
Can anyone help me to understand what it means?
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?
Thanks a lot in advance.
