Tools > Join overlapping Areas

Keyboard shortcut: Shift+J

Join areas that overlapping each other.

You can select two or more closed ways.

• If one way is surrounded by the other(s) a multipolygon will be created automatically.
• Usually, the order of selection matters, as the remaining way will keep the object id and object history of the first selected way with positive id. See #9599.
• All tags with only a single value from all ways will be added and the Tags/Memberships Conflict Dialog will open if manual decisions are needed or memberships are involved. In normal user mode it will additionally warn before adding any tag or membership the ways do not have in common, like Combine Ways, see Combine Confirmation.
• If a selected way does not overlap with any other selected way nor is surrounded by any other selected way, it is silently dropped of list of ways to join and left as is.
• Additionally selected nodes do not matter

Notifications

If the selection does not fit Join Areas needs, following notification messages will be presented, if:

• all selected ways are not overlapping and no selected way is surrounded by another selected way following notification is presented and no changes are made.

• one or more selected ways are not closed.
