I have a polyline feature class called line_1. What I want to achieve is the edge_vertex topology. Specifically,
- I want to generate a new polyine feature class called line_1_new, by adding two new columns to line_1, start_v_id and end_v_id.
- I want to generate a point feature class from line_1. The point feature has an attribute called v_id, corresponding to the start_v_id and end_v_id attributes.
I have used the method of Feature Vertices To Points to generate a point feature class of both ends of the lines. However, the point feature does not contain the topology explicitly. For example, if two lines intersect at a junction, this method will generate two points corresponding to the junction, even though these two points have the same coordinates.
