Any MSA calculated by SkyDemon can hence be totally misguiding. Is the reason that SIA uses a difference obstacle database than the one which is made available to SkyDemon? SIA means Service d'Information Aeronautique, it's a government body, I would find it questionable that such an official institution retains safety information such as obstacle data.

Group: Forum Members Posts: 28, Visits: 85	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?
