The system that IPACS uses at this moment for placement of the trees simply isn't precise enough. The trees show up in the oddest places. Hopefully they will find or create a new system for this. Or maybe addon developers like ORBX may come up with a solution. There placement of trees in TrueEarth (for P3D right now but to be releases for AFS2) is absolutely spot on and almost perfect! So it CAN be done. But until then you will have to get used to trees on roads, houses, airports, etc.: there is nothing you can do about it yourself.

There's everything you need for an accurate tree placement in cultivation using ScenProc.
The "only" issue is finding a good database, because OSM is quite exhaustive regarding building footprints (no info on height and roof unfortunately), but less complete when it comes to vegetation.
In Europe, a good source for vegetation is CORINE.
There are also official cadastral databases that may be very exhaustive.
Scenproc can then automatically generate wide coverage of buildings, trees and lights cultivation.

Thank you both, I'll try Scenproc but don't know if this is so easy.
