sharp edge between remsnik and vitanje

I noticed that there is a sharp edge (way 168290205) running from remsnik straight south to vitanje. according to the note assigned to the way (“Bing 2011”) I assume that there has been no sat imagery to the west of the way at the time the way was added.

well, now it is, just in case somebody wants to complete the forest westwards :wink:

Which imagery layer covers this area? I still cannot find one in high enough resolution to be usable for mapping.

MapBox Sattelite covers this area.
It is not available for a long time. It is added to JOSM. Tracing is allowed. I don’t know from when are the pictures.

Images also covers part west from Slovenj Gradec.
