Multipolygon

Multipolygons are one of two methods to represent area areas in OpenStreetMap. While most areas are represented as a single closed way closed way, almost all area features can also be mapped using multipolygon relations. This is needed when the area needs to exclude inner rings (holes), has multiple outer areas (exclaves), or uses more than ~2000 nodes.

In the multipolygon relation, the inner and outer roles are used to specify whether a member way forms the inner or outer part of that polygon enclosing an area. For example, an inner way could define an island in a lake (which is mapped as relation).

Bus route

Each variation of a bus route itinerary is represented by a relation with type=route, route=bus and ref=* and operator=* tags. The first members in the route relation are the nodes representing the stops. These are ordered in the way the vehicles travel along them. Then the ways are added. In PT v2 the ways form an ordered sequence, along the stop nodes. The ways don't get roles. If they form a continuous sequence this is apparent from the continuous line along them (in JOSM's relation editor).
