<pre class="moz-quote-pre" wrap="">Hello Frank,
Could you elaborate on „first item“ as I just digitized a vector map
with three lines and crossed them with a profile and got back three
distances.
Things to check – do all lines have a CAT value in specified layer?
If you have a problem with a specific data set, you can send me it
off-list so I can take a look.
Māris.

Hello,
I need to identify vector lines (like roads, rivers) crossed by a
transect and get distance from the beginning of the transect. For the
moment I'm using v.profile but it returns only the first item. Is there
any way to get all crossed lines ?
Thank for your help,
Frank
