[OSM-talk] Is a sports pitch an inner of a forest relation?

[Michael Heißmeier]

If the pitch is a hole inside the forest then this is exactly how it should be
mapped. Multipolygon relations are used to describe any swiss-cheese-like shape.
The ways which define the outer contour get the 'outer' role and the ways which
describe the holes receive the 'inner' role. Each of the outer contour and holes
may consist of several ways provided they do not overlap. The OSM wiki page
https://wiki.openstreetmap.org/wiki/Relation:multipolygon contains some drawings
to illustrate this.
