When working with polygon features, such as streets or rivers, it may be necessary to create a centerline representing the flow of the traffic along the center of a linear geographic feature.
The instructions provided describe how to create centerlines from polygon features in ArcMap.
In ArcMap, there is no single geoprocessing tool that automatically performs this task. The tools used in this procedure require an ArcGIS for Desktop Advanced license.
Note: Centerlines can only be created between open-ended lines and not inside closed lines.
Note: The maximum width parameter must be set when creating a centerline. Set the maximum width greater than the width of the dual-lines. For example, if the width of the road is 50 meters, the value for the maximum width parameter is 100 meters. Suitable parameters must be used to obtain better results.
