[talk-au] National borders (was: import of state borders?)

[Ian Sergeant]

It has also been pointed out that having the two inner poly's of the
NSW relation (ACT and Jervis Bay Territory) while having the outer
border of the poly incomplete is causing mapnik and nominatim to think
that both territories are in NSW.

I'm presuming the algorithm being used has difficulty telling which
side of a inner poly is the exempt area when the outer boundary is
incomplete, even though this seems to be computable.

Presumably this effect will go away when the boundary is complete.

Ian.
