Hello everybody,

I am trying to understand if GRASS fits me with its v.lrs module and how
can I use it

I work as a marine surveyor mainly in the offshore oil & gas industry,
occasionly cable & environmental as well.
In this environment, everything is referenced to a (p)line and its offsets.

Offset here are usually meters off a line, + or - outside a line (depending
on bearing), which is a different referencing method than the one used in
v.lrs, correct?
I.e.

-------A------------------
0----1----3----4----5----6
--------------------------
-------------------B------

A = KP 1.25 DX =  1
B = KP 4.75 DX = -2

where:
KP = miles post (distance from start of line)
DX = offset

I loose myself in here already, didn't really understood if grass can
manage this method...?

so, stop the questions to this one for the moment but watch out cause more
will come.. :)

Thank you and have a good day
