<div dir="rtl"><div dir="ltr">Hi All,<br><br>I'm trying to use <a href="http://v.net" target="_blank">v.net</a> distance as follows:<br><br>I use 3 maps (2 point vectors for locations and 1 polyline vector for roads).<br>
I used <a href="http://v.net" target="_blank">v.net</a> twice to connect points to the network as follows: <b><br>
<a href="http://v.net" target="_blank">v.net</a> input=myroads points=fillsite output=myroads_net1 operation=connect thresh=6000 alayer=1 nlayer=2<br></b><b><a href="http://v.net" target="_blank">v.net</a> input=myroads_net1 points=set1 output=myroads_net2 operation=connect thresh=6000 alayer=1 nlayer=2<br>
<br></b>Than I have added a column to myroads_net2 named cost (double precision) and updated it with the value 1, since I wanted all the roads to have the same scale.<br>Than I was using v.net.distance as follows:<br><b>v.net.distance input=myroads_net2 output=test1 afcolumn=cost from_layer=2 to_layer=3<br>
<br></b>In the manual it is written that a table will be created and linked to the output map (test1) and will contain the from and to category and the distance. The problem is that it doesn't happen: there are no geometrics displayed by <b>test1</b> and no tables attached to it. When I've tried to view the attribute tables it has printed that I've to connect it to the database by manage tables.<br>
<br>What can be the problem and how can I fix it?<br><br>Best,<br><br>Dor<br></div></div>
