Reduce the number of nodes in a way, but keep the general shape.

Implementation details

After 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.

The tool uses the Ramer–Douglas–Peucker algorithm for way simplification, but makes sure that tagged nodes and nodes with more than one parent way are not deleted.

    • area of the triangle ABC is lower than 5 m2
    • distance of B to the line AC is lower than 3 m
    • angle ABC doesn't deviate more than 10° from 180°
