Just separating things out into separate files that are loaded at
different zoom levels.  That will cause Xastir to not have to look
at the file at all if you're outside its extents or outside its zoom
limits.

Unfortunately different people have different mapping needs.  I
didn't download or care about school boundaries until we were
thinking of moving because of the schools and I wanted to eliminate
looking at houses that were not inside school boundaries of
interest.

In SAR, we usually want as much detail as possible, whether or not
you might normally need those features for vehicle navigation.  When
navigating on foot or via helo, it's important to know what all
visible features are and where they appear on the map.
