Hi all,<br>
<br>
I'm looking for a tool / workflow on how I can create mileage points<br>
basing on a track. I hope that's the right vocabulary here, but I'll<br>
describe what I want anyway ;-)<br>
<br>
I have a bicycle track and I want to get the points after a specified<br>
(cumulated) distance - say you start at (an artificial) 0 starting<br>
point and now I want a point on the track every 1000m or so. So you'll<br>
get a point after 1000m, 2000m, 3000m and so on just until the track<br>
ends.<br>
<br>
Is there a tool with which I can achieve what I want? Or do I have to<br>
dive into the Python interface to do this programatically?<br>

What you are speaking about is called a "Linear Reference System", and GRASS has the v.lrs.* suite of tools to deal with that.<br>
