black dots
Black dots appear on the map (https://opentopomap.org/#map=9/62.0904/14.0570)
They seem to be overlays, and don't appear on openstreetmap.com.
@der-stefan This seems to be an issue with SRTM data. From where are you importing those? Then i could check if it is an error based on SRTM or not.
I have checked the SRTM files (if you have downloaded them from http://viewfinderpanoramas.org/dem3.html) and the height seems to be okay. So it is either missing/wring data in the database or some overlays which shouldn't be there.
I experience this too (in fact, in the very same area as Mr-C-Kite shown). It has been like this for years, but it would be awesome if the issue was fixed. What's the status on that? Can we do something to troubleshoot it further? Thanks!
