I'm comparing Skydemon and the last 1/250000 SIA Paris Area Chart
Most of the obstacles of the SIA Chart are not on Skydemon map.
There must be some sort of filter used by SkyDemon to show only some obstacles and not all of them. Can we have the rule of that filter?

I believe the data we use is basically the same as what the French publish in their AIP for pilots. If they are omitting an obstruction from their AIP which could be dangerous to aircraft, please let them know.
