thanks for the quick reply :)

re: levels

that clearly is mapping for the renderer and should be avoided. Every "map" makes choices as to what is displayed in what way and thus should not be lied to just to have a certain effect when viewing the data displayed by one certain renderer.

re the paths: we map what's there. If it's private we have access tags. If there are gates we map the gates. So once the data is gathered we should not remove it without very good reason (and private access isn't such a reason).

safe travels
