Tools > Join overlapping Areas

source:/trunk/images/joinareas.svg Keyboard shortcut: Shift+J

Join areas that overlap each other.

You can select two or more closed ways.

  • 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.
  • If areas are surrounded by the others and have no intersection with any of them, then the result of this action will be a multipolygon.

Notifications

If the selection does not fit Join overlapping Areas needs, then these notification messages will be presented:

  • No overlapping areas in the Selection.
    No intersection found. Nothing was changed.
  • An open way is in the Selction.
    One of the selected ways is not closed and therefore cannot be joined.

No action is performed in these cases.
