Regarding my workspace example, since computational errors can not be avoided anyhow, the middle point may not always touch strictly with the original line. Inserting a Bufferer between the Snipper and the SpatialFilter might be more effective to select areas surrounded by green lines. However, I don't think only that will be enough to get the ideal result, because there seem to be some other exceptional conditions in the actual data. We can suggest approaches to solve specific issues, but cannot find all the conditions on the actual data. You will have to specify every condition by inspecting data in more detail, choose an appropriate solution for each condition and integrate them to complete your project.
In such a process, we could help you to think about solutions for specific issues.
