[GRASS-user] LRS and Documentation

Hello everybody,

i am doing the tutorial from:
http://grass.itc.it/grass63/manuals/html63_user/v.lrs.create.html

and all seem fine, until I run the last command (v.lrs.create).
v.lrs.create --o busroute points=busstops out=route_lrs err=lrs_error lidcol=lid pidcol=lid rstable=route_lrs thresh=50

This is the error:

WARNING: Not enough points (0) attached to the line (cat 1), line skip.
..
WARNING: Not enough points (0) attached to the line (cat 16), line skip.

After that out_lines is empty and lrs_error show the whole network.
Am I missing something?

Thank you

Luca

Hi Luca,

maybe you need to run v.net on the network first, see
its man page for instructions to add missing nodes.

Hi Markus and thanks for your answer.

With v.net i have created a new node file for my network ( to be sure that node are connected to network).
Using that one as "milestone" I have 5 lines that go in the right output and 11 that go in the error one with the same warning then before.

Bye

Luca

Hi Luca,

I have tried the example (GRASS 6.3.CVS), no error messages...
