Simplifies polyline features by removing points and simplifying bends.
The “Simplify Polylines” tool allows simplifying polylines by removing excessive bends. At that, polyline shape remains as is.
Supported simplification algorithms:
- Point remove - removes redundant points from the polylines shape. The algorithm is faster but provides more coarse simplification output.
- Bend simplify - removes minor bends along the polylines while preserving the shape of the original polylines. The algorithm provides better and more appealing simplification output, although is known to be slower in most cases.
The tool can be used for creating generalized layer from the existing layer (for example, to display river network at different scales).
Specify a degree at which the simplification operation may affect the input polyline features:
- Point remove - simplification tolerance means maximum allowable offset.
- Bend simplify algorithm - tolerance means length of the reference bend baseline.
