I don't know what the right one is?!

Hi flother,

just to be clear: I did not copy anything from map.is and even don't use their map as a background layer while editing. I only found the names of some landmarks in their maps and added it manually into OSM. I guess the name of a lankmark does not have a copyright ;-)

Regards,
Steffen

maybe...
