[Talk-us] National Forest boundaries (Mike Thompson)

[stevea]

Continuing from my previous post, we even have an especially data-compact (efficient) way of representing that:  the member of the forest relation which is an inholding (tagged with role inner) IS the polygon of, say, a private residence "inside of" the forest.

For example (I'm making this up), say we have a national forest with a small shopping area (for food, supplies...) near its center for convenience.  I could see one polygon (tagged landuse=retail, name=ABC Forest Shopping Center) both BEING exactly that, AND being included in the (enclosing) forest multipolygon as a member tagged "inner."  Voilà, double-duty and done.
