The map control should have the ability to disable the spring animation separately for panning without disabling zoom animation.

This feature is implemented already for the WPF version of the RadMap control (you can use SpringAnimationsMode property). It seems quite difficult to implement the same for the Silverlight version. The difference between WPF and Silverlight is the MultiScaleImage control. In the WPF we use our own implementation of the MultiScaleImage , so we have a full control on its behavior. In the Silverlight we use standard control which does not provide similar functionality.

The MapPolyline should support the driving direction feature. It should be able to displaying arrows.

The VisualizationLayer does not always show items when the RadMap uses a custom map provider which uses a custom UTM map projection.

The map navigation buttons will support the functionality like the auto-repeat when a key is pressed.

When RadMap is used within a popup and the map provider is assigned each time before the popup is opened then UI hangs when it is opened second time.

Workaround:

The problem occurs when the RadMap.Provider property is assigned second time when the popup is opened and then it is closed. You can assign this property one time only to avoid this problem. You can do it from a XAML code. Or you can check that the provider is already assigned in the codebehind like following:

private void MapButton_Click(object sender, RoutedEventArgs e)
{
    if (radMap1.Provider == null)
    {
        radMap1.Provider = new OpenStreetMapProvider();
    }
 
    PopupPosition.IsOpen = true;
}

The RadMap control should support displaying copyright info about currently used map provider.

Add support for map grid (i.e. grid-lines).

The MapShape data template does not allow to use event triggers like to the following way:
<telerik:MapPath Stroke="{Binding Stroke}" Fill="{Binding Fill}"  StrokeThickness="1" Data="{Binding Geometry}">
    <interactivity:Interaction.Triggers>
        <interactivity:EventTrigger EventName="MouseLeftButtonDown"> 
            <interactivity:InvokeCommandAction  Command="{Binding MyCommand}"/>
        </interactivity:EventTrigger>
    </interactivity:Interaction.Triggers>
</telerik:MapPath>

MapPolyline (Informationlayer) or PolylineData (VisualizationLayer) disappear on higher zoom levels.

The origin of this issue is that Silverlight has limitation for the size of the polyline objects. Once this limit is reached, the calculations are wrong and the polyline is displayed incorrectly.

Possible workaround could be adding multiple smaller polylines / lines instead of one big polyline with many intermediate points.

Add ability to change visibility of the information layer depends on the zoom range.

1. If you make two single mouse clicks fast enough, they will be incorrectly interpreted as double click, no matter how far one click from another. And you will be zoomed to the place of the first click.
 
2. Also there is another rated issue with fast map scrolling.
 If I'm at 16 zoom and want to scroll map to other city to the left (without zooming out). To do this I will need to mouse-down at the left edge, then move to the right, then mouse-up near right edge. If you repeating this fast enough, most times you get zoomed in instead of map moving.

Steps to reproduce:
For example, here - http://demos.telerik.com/silverlight/#Map/GeoImageryProviders
 
Just click to Sofia, then quickly click to Bucharest. Map will be zoomed in to Sofia instead of moving to Bucharest.
Quickly = in 200-300ms.

The ImageProvider should support the scenario when the geographical region which is covered by the provider should be moved.

When you draw a MapPolygon with one of his points as 90 latitude then the memory keeps increasing and the application crashes.

The map control should validate locations to prevent using coordinates which do not correspond to the used map projection.

For better performance the dynamic layer should be able to request items after the panning / zooming is finished only.

XAML team recently reviewed this request and decided not to address it in the future. Use the newer VisualizationLayer instead.

When application has two radwindows, each with a radmap with MaPpolyLine, then the polyline disappears after click in the one window.

The MapLayer will contain new ZIndex attached property which could be used like the Canvas.ZIndex property for elements of the information layer.

ClusterGenerator's AutoExpandWhenSingle property is set to true by default.

Adding a single item in the VisualizationLayer with Clustering enabled results in a single cluster which is not expanded but it should be.

Available in LIB Version 2014.3.1326.

The map control should support new Birds Eye features to be able to use tiles of bing map provider which are created for zoom levels lesser than 19.

The encoding of DBF-file is determined automatically by MapShapeReader. When the file has the unicode fields then the reader does not convert unicode characters (å,ä,ö) properly to the extended data. Currently the MapShapeReader does not contain property to assign the certain encoding for DBF-file.
The MapShapeReader should support to assign the certain encoding for DBF-file including UTF-8.

When the RadPane that contains the RadMap is redocked to another location then the RadMap locks the browser.
The RadMap loses its data context and gets null into Provider property. When the data context is restored and the RadMap gets its provider then it hangs, because all calculations inside its logic require map provider which contains necessary information about current projection.It is no problem to change map provider from one to another, but the problem occurs when the map provider is changed to null. 
At least the RadMap should raise exception in a case when the Provider property is assigned to null.
