Tools > Simplify Way

Keyboard shortcut: Shift+Y

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.

• SimplifyArea plugin - despite the name, also simplifies ways. Uses a different algorithm and has more parameters for tuning. In particular for nodes A, B, C the node B is not deleted unless
  • 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°
• Distribute Nodes
