I abandoned Skydemon a while ago, because I don't trust Skydemon any more.
We all fly quite addicted along Magenta Lines, so charts have to be
precise.
So, i.e. why are NOTAMS not shown correct in Skydemon? Example:
This 'Center' is not centered and maybe the planned flights corridor does not exist in reality!?
I realized the discrepancies when using a trial of ForeFlight Europe with the graphical NOTAMs update.
Taking some random NOTAM circles and inserting the center it seems Skydemon is sloppy in processing data.
Added this i.e. to the discussion on why they use rhumb lines instead of great circle and other behavior.
Decided I am out of Skydemon for now, too potentially dangerous for me flying.
I do like the charts representation clear structure, but cannot live with wrong data.
My 2 pennies.
