Hi Roberto,
I wait for that as well. Unfortunately it is not an easy thing to accomplish, it takes some effort and time, and then it would have to get distributed (bandwidth!).
Iirc, there have been some tiles "fixed" a while ago, so if you see major data faults like huge spikes or deep rifts then it´s worth to file a bug-report to Laminar.
For a global "scenery recut" we will have to wait, I suspect it might take until the next version of X-Plane...
Cheers, Jan
