Tools > Create Multipolygon

source:trunk/resources/images/multipoly_create.svg Keyboard shortcut: Ctrl+B

This tool quickly creates a source:trunk/resources/images/data/multipolygon.svg multipolygon, one of the most common source:trunk/resources/images/data/relation.svg relations.

Selected source:trunk/resources/images/data/way.svg ways will be members of the multipolygon with appropriate roles, outer or inner, and most of the tags in common are moved from the outer ways to the multipolygon.

Examples

A multipolygon with single outer ring and single inner ring

  1. Select a relation members that would form:
    1. an outer ring (ways) - in this demo we will use Select > Non-branching way sequences to speed up process.
    2. an inner ring
  2. after all members selected, activate a tool
  3. enter details using presets, Tags/Membership Dialog or Relation editor
  4. This tool creates only valid multipolygons, but you may optionally check that new mutipolygon contains no mistakes using validator, as there might be mistakes after human intervention.

A new relation with single tag type=multipolygon would be created. You can add more details, using tags such as natural=water for water objects and so on.
