Hi Lilla,

maybe I did not got the full complexity of your problem. If the first step is extracting data along a line, this is easy: Use the sample tool. Read the doc/UserGuide.pdf Chapter 6.5 'Sampling data'.

Hello Daniel

My problem, that I need to reach inside my code the data on the line. If I use the sampling utility, i will have them in distinct files. However, I try to find back, how the sampling utility extract the data, so thanks for the idea.
