I can't draw between two coordinates

#1

 


The code below is copied from "HowDoISample" but does not draw between two coordinates.

do you think to help me ?

Ayhan,
Sorry for the delayed response.
After checking the data you attached, I found where the issue lies. In you sample you used GoogleOverlay and set the MapUnit to Meter, but your rtg data is built in DecimalDegree, so the Route you get from this file is also in DecimalDegree, that’s why the Route won’t be displayed on the Map.
You can try to apply the code snippet below to your FindPath method in the application; there we add a projection process to the Route you got from the original rtg file.
RoutingLayer routingLayer = (RoutingLayer)Map1.DynamicOverlay.Layers["RoutingLayer"];
 
            routingLayer.Routes.Clear();
            ManagedProj4Projection projection = new ManagedProj4Projection();
 
            projection.InternalProjectionParameters = Proj4Projection.GetEpsgParametersString(4326);
            projection.ExternalProjectionParameters = Proj4Projection.GetGoogleMapParametersString();
            projection.Open();
 
            MultilineShape projectedRoute = projection.ConvertToExternalProjection(routingEngine.GetRoute(txtStartFeatureId.Value, txtEndFeatureId.Value).Route) as MultilineShape;
 
            routingLayer.Routes.Add(projectedRoute);
            projection.Close();
            //routingLayer.Routes.Add(routingEngine.GetRoute(txtStartFeatureId.Value, txtEndFeatureId.Value).Route);
            Map1.DynamicOverlay.Redraw();
 
Further questions please let me know.
 
Thank you.
James

Thank you, James.


 There is also a Code Community sample that deals with that issue, Routing with Projections wiki.thinkgeo.com/wiki/Map_Suite_De...rojections


 In this sample, the projections scenario is different but the principle applies. Ayhan, you can check it out, if you'd like.
