I'm currently working with street intersections trying to find point(or points) where 2 given streets intersect(!disjoin). Streets are all Polyline features, and I have to work with 2 features at given time. I think this way it can be determined if they intersect(haven't yet tested it),
public List RoadIntersections(IPolyline poly1, IPolyline poly2) { IRelationalOperator ro = null; ro = poly1 as IRelationalOperator; ISegmentCollection sc = new PolylineClass() as ISegmentCollection; sc.AddSegment((ISegment)poly2); if (ro.Disjoint(sc as IGeometry) == false) //if they intersect { //TODO: find intersection points } ...but what I would like to do is to find point (or points) where those two polylines intersect.
