Split Polylines

Parameter

Comments

Input features
<in_features>

Input polyline features to be split into segments.

Output feature class
<out_feature_class>

The new output polyline feature class that will store the split polylines.

Split method
<method>

Splitting method that will be applied to the input polylines.

• AT_ALL_VERTICES - input polylines will be split at all vertices, the number of output polylines depends on how many vertices exist in the input polylines.

Note

In some cases the vertices density can be high enough so that applying this method will result in great many of short polylines. In such cases you can apply the Show Nodes tool first, to figure out how many nodes (vertices) are there in the input polylines.

• INTO_SPECIFIED_SEGMENTS - input polylines will be split into segments of the specified length (except the last segment), at that splitting always starts from the start (from) node of the input polylines.

• INTO_EQUAL_SEGMENTS - input polylines will be split into given number of equal segments.

• AT_INTERSECTIONS - input polylines will be split at all intersections within the input polyline layer. This option is similar to the ArcGIS Planarize tool and can be useful when dealing with non-topological or spaghetti digitized line work.

• BY_ANOTHER_LAYER - input polylines will be split at the intersections with another specified polygon, polyline or point layer (or by selected features of another layer).

Notes:

- When polylines are split at intersections with other layers they are split at self-intersections as well.

- When splitting by point layer it is highly recommended to specify and use tolerance, otherwise make sure that points are located exactly on the polylines.

• AT_ALL_DIRECTIONS_CHANGE_POINTS - input polylines will be split at the points of change of the direction.

• AT_SLOPE_CHANGE_POINTS - input polylines will be split at the points of change of the slope.

Segment length
{interval}

Specify length of segments that input polylines will be split into.

Segment count
{seg_count}

Specify number of segments into which input polyines will be split.

Split layer
{split_layer}

Specify another polygon, polyline or point layer, input polylines will be split at the intersections with this layer.

Tolerance
{point_tolerance}

Specify tolerance value used when polylines are split by points.

ID field
{id_field_name}

Specify ID field in the output feature class in which IDs of the input features will be stored. Leave this field blank if you do not wish to keep input features IDs.
