Input features

<in_features>

Input polyline features to be simplified.

Output feature class

<out_feature_class>

New output feature class that will store simplified polylines.

Simplification algorithm

<simplify_alg>

There are two simplification algorithms available:

• POINT_REMOVE - this algorithm being selected removes redundant points from the polyline shape. The algorithm is faster but provides more coarse simplification output.

• BEND_SIMPLIFY - this algorithm removes minor bends along the polylines while preserving the main shape of the original polylines. The algorithm provides better and more appealing simplification output, although is known to be slower in most cases.

Handling topological errors

<handling_errors>

In some cases the simplification operation may result in topological errors, these can be handled in the following ways:

• NO_CHECK - No check for topological errors will be made.

• FLAG_ERRORS - Topological errors will be flagged, if any.

Simplification tolerance

<tolerance>

The degree at which the simplification operation may affect the input polyline features can be specified as simplification tolerance:

• For the Point remove algorithm tolerance means maximum allowable offset.

• For the Bend simplify algorithm tolerance means length of the reference bend baseline.

Keep points

<keep_points>

When the simplification algorithm leads to the collapsed polylines with zero geometry there is an option to keep such collapsed polygons as points:

• KEEP - Specifies to keep the collapsed polylines as points. The points will be stored in a point feature class at the output feature class location, taking the name of the output feature class plus a suffix _Pnt. This is the default.

• DROP - Specifies not to keep the collapsed polylines as points even if they are found in the process; the empty point feature class will be created.
