Hello and welcome to OpenStreetMap!,

On this changeset you've used a "source=Google Maps" tag. We can't actually use that as a source in OSM because Google's licence doesn't allow it to be used here - it would cause real problems for the project if we were found to be using Google Maps as a source.
If this is somewhere that you are familiar with, then "source=local_knowledge" would be perfectly OK. If not, we'll have to undo this change.

Best Regards
Andy Townsend, on behalf of OSM's Data Working Group
