Navigraph now has Rogers VFR overlays for Europe included in Charts. Just looking at them now, very nicely done.
You can get the map legends as PDF downloads from Rogers website.
Are Rogers vector-based or scan? If it’s scan… it looks like last century technology.
Looks to be raster based, but quite a decent resolution, similar to the FAA sectionals.
Just got back to it, and sad to see the maps are at least a year old, and outdated for my home airport. 
If you bought these it would cost a fortune. Im happy they are included in the navigraph sub even if mildly out of date.
Mildly out of date, means every frequency in Norway is wrong.
Norwegian CAA has VFR map accessible for free btw

Maybe not really relevant to the thread
