I need just center point of polyline that belongs to polyline.
Ok, I'll do it with Linear Referencing System of NTS (C# port of JTS)
[WebMethod(EnableSession = true)]
[ScriptMethod(UseHttpGet = true)]
public string GetCenterPoint(...)
{
//...
return new NetTopologySuite.IO.WKTWriter().Write(new
NetTopologySuite.Geometries.Point(LengthLocationMap.GetLocation(geometry,
geometry.Length/2).GetCoordinate(geometry)));
}
