Hello! In particular about road mapping

Hello gosausee!

Thank you for your correction. I had images from OSM for mapping. Can you share some local features of mapping for Switzerland. I would be very grateful for information.

Best regards,
Vika

This happened due to different mapping tools and I fixed two roads that don't have a common point of either a bridge/tunnel, so I corrected this according to the satellite imagery. You, as a local resident, have more up-to-date data and have the right to correct it as you see fit. It will be more correct.

I mean the suggestion of OSM ID tool to fix the connection of roads, when roads don't have a common intersection

Hi, tomhukins!
Thank you for your comment. In this case, I slightly tweaked the connection of roads to fix the error on OSM. I agree that I should describe in more detail what I'm correcting or contact the mapper directly for this.
Best regards, Vika
