Invalid multipolygon relations are currently responsible for several issues (clarisma/geodesk-py#29, clarisma/geodesk-py#30, clarisma/geodesk#52) -- gol build should remove (or fix) them.

Proposed approach:

  • Keep broken MP relations, but don't treat them as areas; store them as regular relations instead

  • To be considered an area, an MP relation must have at least one member way with role outer

  • An MP relation will be included as an area even if its geometry is invalid
