Smoothing Lines in a List of Points

GregEdwards — Fri, 02 Dec 2011 14:22:23 GMT

We are receiving a list of points, and adding them to a map layer as a polyline. Using ESRI tools, how might we convert the line segment into a smoothed line segment using Bezier Spline or an equivalent?

Thank you.

The code looks something like this:

var pointCollection = new Geometry.PointCollection();

//IN LOOP:

pointCollection.Add(Transform.GeographicToWebMercator(new MapPoint(latitude, longitude)));

//AFTER LOOP IS COMPLETED:

var polyline = new Polyline();
polyline.Paths.Add(pointCollection);
polylineList.Add(polyline);

You can cast the polyline into IPolycurve, then call Smooth method to convert into a smooth curve that containing only Beizer curve segments.
