I found out, I didn't cite the source: https://maps.flurnamen.at/; for all local names of forests, fields, meadows, wetlands...

Oh, yeah, sorry, I ve never been sure about these arrows. So they are always down, like for cliffs (I thought about it more like barrier against river).
Thanks. Errors fixed now.

Hi! Thank you for note.
I agree about weir.
Although not really understand, what you mean with the convention? Possibly my "man_made=embankment" in near, on the river? For that, I found out it really should be inversed.

Have you possibly walk over there? Because I have worked only with web resources.

Yes, thank you. I have now corrected the errors, the path is connected.
