Hi there,

even if myself did not encouter severe issues within Germany yet there are some very bad vibrations on SD chart accuracy especially in Italian and German charts. Compared to physical ones there is a deviation between for example location of CTRs/ED-Rs/VFR routes and so on thus you cannot rely on that.
You can find more detailed info in a German forum of the very well known magazine "Pilot und Flugzeug" unfortunately only in German language:
https://www.pilotundflugzeug.de/forum/2014,01,31,21,3039439

It is worth reading it because many German pilots are building their opinion upon that and the most important thing of a moving map is accuracy in charts. I think articles like this one prevent thousands of potential users subscribing to SD. Therefore please focus on accuracy instead of features as the tool from that perspective is leading egde so far...

Having that said I will always compare my tracks against physical charts and will report any inconsistence.

Cheers,

It is, but it is not suitable for use as a source of medium-scale transportation data (roads and railways). It is simply too detailed.

We are investigating in the background whether we can do any processing of OSM data (or pay someone else to do it) to make it suitable for our needs.

Isn't there some kind of associated database which would classify each road according to importance or rank? A simple filter on that data field should do the trick. But then I don't really know anything about the OSM data format. But certainly, if you could find a way to use these data you'd be home safe.

Hi Tim,

regarding OSM background data: I, too, had the problem in a project with my company, that we wanted to retrieve vector maps (to our own proprietary format) from OSM but found them to be often too detailed.
In the end, I set up some GIS server and run customized queries which also did some simplifications to reduce too complex polygons, lines, etc. (like removing too many verticies, removing very small lakes, forests, ...)
On the other hand, esp. roads are still very accurate at our required zoom levels.
PM me, if you are interested in more details.

Cheers,
Markus
