I have calculated route. When I draw it on xServer.NET it looks diferent then in PTV Navigaion SDK.

Dzien dobre,

let's compare different perspectives and contributions. Here's my assumption:

You calculated a route with the xRoute2.calculateRoute and requested some result fields: polyline and guidedNavigationRoute. The polyline contains a large number of hundreds or even thousands of points that create a line that completely follows the whole segment network (on a visual level). At the same time the guidedNavigationRoute contains only a small subset of those points: only those so-called magnetic via points (MVP) that are needed to push a re-routing on the navigation device to follow the original route (e.g. if you follow a highway for hundred kilometers we only need a few MVPs
When you trigger a navigation process based on the MVP as contained in the BCR file the mobile device decides autonomously how to get from one point to the next one. Depending on the routing options on the mobile device the geometry of the route may look different.

Does this resolve the question?

Best regards,
Bernd

I've attached a screenshot. There you will see that the MVPs are on the exact position as the SDK is calculating the route. So the error lies within the creation process of the BCR with Guided Navigation.

This doesn't resolve the question. We need to display route exactly like in xServer.net. Is there any other method to do that? Can we draw polyline in PTV Navigation SDK?

Hello Mateusz,

I'd like to reproduce the whoile story. Could you please provide the xRoute request and the complete response?
First potential question is then "does the response polyline" look equal to the "BCR viapoints"?
Feel free to send it via email to bernd.welter@ptvgroup.com if the request is seen to contain "confidential" data.

I'm sceptic

Request and response are in attachments. Is there any method in api to draw polyline in PTV Navigation SDK?

Got it:
the two different geometries have been caused by some mistake. The pictures / geometries are based on
- shortest route
- fastest route
