When opening i.e. EDNX - Oberschleissheim, it seems that these aren't vector graphics anymore but instead pictures, as you can clearly seen on the below picture from the approach chart ( ~ 7,8MB) with all the compression artefacts. Whereas i.e. the arrival chart (~1,8MB) and apporach chart (~0,6MB) from EDDE - Erfurt is still crisp clear vector graphic. Was this already all the time, that some charts were pictures? Or might this be a bug ad SD during processing? Or is this part of the DFS "Quality Offensive" to even mock more the paying general aviation? Best regrads

This is obviously undesirable. I think we've asked them before about this, but since you've illustrated a great example above, I will ask them to comment on that directly and get back to you here. now I'm really getting confused. So the free data is no good because it's poor quality and not georeferenced and SD wants to keep the high-quality version. Frair enough. The paid version is also poor quality now (just subscribed a few weeks back...)?!
