I'm using the v.lrs.create module to make a table of distances between mileposts along some trails. Some of the trails "double back" on themselves. i.e - a circular route in which the last few kilometers or so overlap the first kilometers and ends at the starting point. So I might have a situation where milepost 19 is identical to milepost 3, and mp 20 = mp 2, and mp 21 = mp 1.
The module fails in these cases (start_mp > = end_mp). Is there any way to work around this? Up till now, I've deleted the last few (overlapping) mileposts, then the module works fine. But I then have to add the final few distances by hand.
Is there any way to work around this?
Thanks
