I am working on a project to create a centerline from a polygon automatically. The user select a polygon and click a button, the centerline will create for him.
I have tried the build-in function “Collapse Dual Lines to Centerline”, but it cannot perform well so I decide not use this function in this project. In further study, I find out some terms such as “Medial Axis”, “Skeleton”, “Voronoi polygon”, those are some concepts related to centerline formation. However, I find difficult to understand those algorithm.
Does anyone have a suggestion to me for this project? Does anyone have a suggestion for how to implement those concepts in ArcMap? Is there any sample script or algorithm I can refer to as reference?
