Bing Maps and Overview widget

ChrisMarston

I am currently displaying Bing Aerial on main map and want to make my overview as Bing Roads, does anyone know how I would code this? Using Flexviewer 3.0

This is what I have coded but it keeps displaying the Bing Aerial in both maps:

<configuration>
    <!-- possible values for initialstate: open or closed (default) -->
    <initialstate>open</initialstate>
    <!-- by default it will use the same basemap as current main map,
         you can hardcode as below if you wish -->
<type="bing" visible="true" key="AjR14SXBBY1RWMyZ9riZJltB3DqUcyUVt_a4ulRXKz-O5sdsQHMVnbjWH964C8Ls" style="road" culture="en-US" />
</configuration>

Thanks All

Well, if you have the source code, it looks fairly simple:

In my overviewMapWidget.xml I have the following:

<?xml version="1.0"?>
<configuration>
    <!-- possible values for initialstate: open or closed (default) -->
    <initialstate>open</initialstate>
    <!-- by default it will use the same basemap as current main map,
         you can hardcode as below if you wish -->
         
       <bing key="your_key_here"/>

       <layer label="Bing" type="bing" visible="true" style="road" culture="en-US" url="placeholder@here.there"/>


</configuration>

basically assinging a nonexistet (dummy) url to the bing layer tag and providing my Bing key. (url can be any non-null)

This will then test for if (url) as true and send it to this part of the OverviewMapComponent.mxml (otherwise, it goes straight to loading from Basemaps):

                    if (url)
                    {
                        useBaseMapLayer = false;
                        type = configXML.layer.@type;
                        useProxy = configXML.layer.@useproxy[0] && configXML.layer.@useproxy == "true";
                        switch (type.toLowerCase())
                        {
                            case "tiled":
                            {
                                var tiledlayer:ArcGISTiledMapServiceLayer = new ArcGISTiledMapServiceLayer(url);
                                tiledlayer.alpha = alpha;
                                if (proxyUrl && useProxy)
                                {
                                    tiledLayer.proxyURL = proxyUrl;
                                }
                                overviewMap.addLayer(tiledlayer);
                                break;
                            }
                            case "dynamic":
                            {
                                var dynlayer:ArcGISDynamicMapServiceLayer = new ArcGISDynamicMapServiceLayer(url);
                                dynlayer.alpha = alpha;
                                if (proxyUrl && useProxy)
                                {
                                    dynlayer.proxyURL = proxyUrl;
                                }
                                overviewMap.addLayer(dynlayer);
                                break;
                            }
  case "bing":
  {
   var veTiledLayer:VETiledLayer = new VETiledLayer();
   veTiledLayer.alpha = alpha;
   veTiledLayer.id = label;
   veTiledLayer.visible = visible;
   veTiledLayer.key = configXML.bing.@key;
                        veTiledLayer.mapStyle = configXML.layer.@style;
   if (style)
   {
    veTiledLayer.mapStyle = style;
   }
   if (culture)
   {
    veTiledLayer.culture = culture;
   }
   overviewMap.addLayer(veTiledLayer);
   break;
   }
                        }
                    }
                    else

The red text is the code I added (copied from several lines below in the same file) and modified the .key to get it from the config. Also modified it to get style, otherwise, you ONLY get streets. This way, it lets you pick "road", "aerial", or "aerialWithLabels".

This is working for me, I have the Bing streets layer in my overview map (nothing else), and it zooms/pans as expected regardless of what basemaps I have visible in the main viewer.
