[mkgmap-dev] cascading multipolygon relations

Wed Apr 1 15:36:57 BST 2009

  In the wiki it is suggested to cascade two multipolygon relations in
a case when we've got area #1 inside area #2 inside area #3:

Looks like mkgmap can't handle this. Should I convert such cases into
some other form of relation, or should I just wait for mkgmap to support this?

A sample of a lake inside swamp, swamp inside forest, currently described
using cascaded relations, which mkgmap can't render:
