     11After simplification, all of the deleted nodes will be closer than the in the popup specifed distance (e.g. 3 m) to the simplified way. In other words, the old and the new way will never be more than e.g. 3 m apart.

     13The tool uses the [https://en.wikipedia.org/wiki/Ramer–Douglas–Peucker_algorithm Ramer–Douglas–Peucker algorithm] for way simplification, but makes sure that tagged nodes and nodes with more than one parent way are not deleted.

    17 You can configure the distance between two nodes in the [wiki:Help/Preferences/Advanced advanced preferences] ({{{simplify-way.max-error}}}, in meters, default value is 3). A lower threshold makes the simplification less aggressive.
