Hello,
I have use your program to map match existing lines. For this i extract point along lines and then from this point i do a map matching.
Sometimes I have multiple lines to map match. The points layer i have in source have a vertex_id and line_id. Would it be possible to do process several line map matching in one command.

For the moment I do it trough a model but it does build the data structure multiple time and take much more time.

Hi,

Please excuse my late response.

Do I understand it right, that your point layer has several trajectories into it or that the point layer has several consecutive points with different line_ids?

This should be possible and does not sound very difficult. I can create a filter using the line_id. But this should be the same like you can do with a model. So I am wondering why it does take much more time. Apply a filter is not a big thing for QGIS (depending on the size of the input layer). Could you provide your model and a test data layer so that I could make some tests?

Sincerely,
Christoph

Yes you do understand well.
to make the process of mapmatching the step to build network is done sevral time each time for each line. (or may be i haven't understand the process).

I will test the scenario for my own. But unfortunately I have very less time at the moment. So please excuse me, that it will take some time. I will inform you about my results and next steps.
